These interfaces take an and will either create an FCoE Controller or destroy an FCoE Controller depending on which file is written to. The new FCoE Controller will start in a DISABLED state and will not do discovery or login until it is ENABLED. This pause will allow us to configure the FCoE Controller before enabling it. 2) Makes the 'mode' attribute of a fcoe_ctlr_device writale. This allows the user to configure the mode in which the FCoE Controller will start in when it is ENABLED. Possible modes are 'Fabric', or 'VN2VN'. The default mode for a fcoe_ctlr{,_device} is 'Fabric'. Drivers must implement the set_fcoe_ctlr_mode routine to support this feature. libfcoe offers an exported routine to set a FCoE Controller's mode. The mode can only be changed when the FCoE Controller is DISABLED. This patch also removes the get_fcoe_ctlr_mode pointer in the fcoe_sysfs function template, the code in fcoe_ctlr.c to get the mode and the assignment of the fcoe_sysfs function pointer to the fcoe_ctlr.c implementation (in fcoe and bnx2fc). fcoe_sysfs can return that value for the mode without consulting the LLD. 3) Make a 'enabled' attribute of a fcoe_ctlr_device. On a read, fcoe_sysfs will return the attribute's value. On a write, fcoe_sysfs will call the LLD (if there is a callback) to notifiy that the enalbed state has changed. This patch maintains the old FCoE control interfaces as module parameters, but it adds comments pointing out that the old interfaces are deprecated.

The similar logic exists in other fcoe drivers, e.g., bnx2fc, so we add a function pointer into the common fcoe_port struct to allow individual fcoe transport implementaion (fcoe and bnx2fc) to get the corresponding netdev associated with a give lport. Then a inline fcoe_get_netdev() is added as part of libfcoe for all underlying fcoe transport drivers to use regardless of its individual fcoe transport driver, and also allows move more common code such as fcoe_link_speed_update or fcoe_ctlr_get_lesb to be in libfcoe, rather than specific to fcoe. This patch is a prep work that adds aforementioned fucntion pointer, and followed by the actual code changes to make use of it.

To differentiate between this platforms venc_type/vpbe_type was passed as part of platform data which was incorrect. The correct way to differentiate to handle this case is by passing different platform names. This patch creates platform_device_id[] array supporting different platforms and assigns id_table to the platform driver, and finally in the probe gets the actual device by using platform_get_device_id() and gets the appropriate driver data for that platform. Taking this approach will also make the DT transition easier.

Aim of DMA helpers - The purpose of device-tree is to describe the capabilites of the hardware. Thinking about DMA controllers purely from the context of the hardware to begin with, we can describe a device in terms of a DMA controller as follows ... 1. Number of DMA controllers 2. Number of channels (maybe physical or logical) 3. Mapping of DMA requests signals to DMA controller 4. Number of DMA interrupts 5. Mapping of DMA interrupts to channels - With the above in mind the aim of the DT DMA helper functions is to extract the above information from the DT and provide to the appropriate driver. However, due to the vast number of DMA controllers and not all are using a common driver (such as DMA Engine) it has been seen that this is not a trivial task. In previous discussions on this topic the following concerns have been raised ... 1. How does the binding support devices with multiple DMA controllers? 2. How to support both legacy DMA controllers not using DMA Engine as well as those that support DMA Engine. 3. When using with DMA Engine how do we support the various implementations where the opaque filter function parameter differs between implementations? 4. How do we handle DMA channels that are identified with a string versus a integer? - Hence the design of the DMA helpers has to accomodate the above or align on an agreement what can be or should be supported. Design of DMA helpers 1. Registering DMA controllers In the case of DMA controllers that are using DMA Engine, requesting a channel is performed by calling the following function. struct dma_chan *dma_request_channel(dma_cap_mask_t mask, dma_filter_fn filter_fn, void *filter_param); The mask variable is used to match a type of the device controller in a list of controllers. The filter_fn and filter_param are used to identify the required dma channel and return a handle to the dma channel of type dma_chan. From the examples I have seen, the mask and filter_fn are constant for a given DMA controller and therefore, we can specify these as controller specific data when registering the DMA controller with the device-tree DMA helpers. The filter_param variable is of an unknown type and is typically specific to the DMA engine implementation for a given DMA controller. To allow some flexibility in the type and formating of this filter_param we employ an xlate to translate the device-tree binding information into the appropriate format. The xlate function used for a DMA controller can also be specified when registering the DMA controller with the device-tree DMA helpers. Based upon the above, a function for registering the DMA controller with the DMA helpers now looks like the below. The data variable is used to pass a pointer to DMA controller specific data used by the xlate function. int of_dma_controller_register(struct device_node *np, struct dma_chan *(*of_dma_xlate) (struct of_phandle_args *, struct of_dma *), void *data) For example, in the case where DMA engine is used, we define the following structure (that stores the DMA engine capability mask and filter function) and pass this to the data variable in the above function. struct of_dma_filter_info { dma_cap_mask_t dma_cap; dma_filter_fn filter_fn; }; 2. Representing and requesting channel information Please see the dma binding documentation included in this patch for a description of how DMA controllers and client information should be represented with device-tree. For more information on how this binding came about please see [3]. In addition to this, feedback received from the Linux kernel summit showed a consensus (among those who attended) to use a name to identify DMA client information [4]. A DMA channel can be requested by calling the following function, where name is a required parameter used for identifying a DMA channel. This function has been designed to return a structure of type dma_chan to work with the DMA engine driver. Note that if DMA engine is used then drivers should be using the DMA engine API dma_request_slave_channel() (implemented in part 2 of this series, "dmaengine: add helper function to request a slave DMA channel") which will in turn call the below function if device-tree is present. The aim being to have a common DMA engine interface regardless of whether device tree is being used. struct dma_chan *of_dma_request_slave_channel(struct device_node *np, char *name) 3. Supporting legacy devices not using DMA Engine These devices present a problem, as there may not be a uniform way to easily support them with regard to device tree. Ideally, these should be migrated to DMA engine. However, if this is not possible, then they should still be able to use this binding, the only constaint imposed by this implementation is that when requesting a DMA channel via of_dma_request_slave_channel(), it will return a type of dma_chan. This implementation has been tested on OMAP4430 using the kernel v3.6-rc5. I have validated that MMC is working on the PANDA board with this implementation. My development branch for testing on OMAP can be found here [5]. v6: - minor corrections in DMA binding documentation v5: - minor update to binding documentation - added loop to exhaustively search for a slave channel in the case where there could be alternative channels available v4: - revert the removal of xlate function from v3 - update the proposed binding format and APIs based upon discussions [3] v3: - avoid passing an xlate function and instead pass DMA engine parameters - define number of dma channels and requests in dma-controller node v2: - remove of_dma_to_resource API - make property #dma-cells required (no fallback anymore) - another check in of_dma_xlate_onenumbercell() function [1] http://article.gmane.org/gmane.linux.drivers.devicetree/12022 [2] http://article.gmane.org/gmane.linux.ports.arm.omap/73622 [3] http://marc.info/?l=linux-omap&m=133582085008539&w=2 [4] http://pad.linaro.org/arm-mini-summit-2012 [5] https://github.com/jonhunter/linux/tree/dev-dt-dma Cc: Nicolas Ferre Cc: Benoit Cousson Cc: Stephen Warren Cc: Grant Likely Cc: Russell King Cc: Rob Herring Cc: Arnd Bergmann Cc: Vinod Koul Cc: Dan Williams Reviewed-by: Arnd Bergmann Reviewed-by: Nicolas Ferre Signed-off-by: Jon Hunter Reviewed-by: Stephen Warren Acked-by: Rob Herring Signed-off-by: Vinod Koul --- include/linux/of_dma.h | 45 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 include/linux/of_dma.h (limited to 'include') diff --git a/include/linux/of_dma.h b/include/linux/of_dma.h new file mode 100644 index 000000000000..337823dc6b90 --- /dev/null +++ b/include/linux/of_dma.h @@ -0,0 +1,45 @@ +/* + * OF helpers for DMA request / controller + * + * Based on of_gpio.h + * + * Copyright (C) 2012 Texas Instruments Incorporated - http://www.ti.com/ + * + * This program is free software;

This part of implementation is based upon V2 of the DMA helpers by Nicolas [1]. During a recent review of RCU, it became apparent that the code is missing the required rcu_read_lock()/unlock() calls as well as synchronisation calls before freeing any memory protected by RCU. Having looked into adding the appropriate RCU calls to protect the DMA data it became apparent that with the current DMA helper implementation, using RCU is not as attractive as it may have been before. The main reasons being that ... 1. We need to protect the DMA data around calls to the xlate function. 2. The of_dma_simple_xlate() function calls the DMA engine function dma_request_channel() which employs a mutex and so could sleep. 3. The RCU read-side critical sections must not sleep and so we cannot hold an RCU read lock around the xlate function. Therefore, instead of using RCU, an alternative for this use-case is to employ a simple spinlock inconjunction with a usage count variable to keep track of how many current users of the DMA data structure there are. With this implementation, the DMA data cannot be freed until all current users of the DMA data are finished. This patch is based upon the DMA helpers fix for potential deadlock [2].

In order to fix the problem, ext4 and btrfs implemented their own writeback functions instead of writeback_inodes_sb(_nr)_if_idle(), but it introduced the redundant code, it is better to implement a new writeback_inodes_sb(_nr)_if_idle().

Wysocki" Date: Wed, 9 Jan 2013 22:33:37 +0100 Subject: ACPI / PCI: Set root bridge ACPI handle in advance The ACPI handles of PCI root bridges need to be known to acpi_bind_one(), so that it can create the appropriate "firmware_node" and "physical_node" files for them, but currently the way it gets to know those handles is not exactly straightforward (to put it lightly). This is how it works, roughly: 1. acpi_bus_scan() finds the handle of a PCI root bridge, creates a struct acpi_device object for it and passes that object to acpi_pci_root_add(). 2. acpi_pci_root_add() creates a struct acpi_pci_root object, populates its "device" field with its argument's address (device->handle is the ACPI handle found in step 1). 3. The struct acpi_pci_root object created in step 2 is passed to pci_acpi_scan_root() and used to get resources that are passed to pci_create_root_bus(). 4. pci_create_root_bus() creates a struct pci_host_bridge object and passes its "dev" member to device_register(). 5. platform_notify(), which for systems with ACPI is set to acpi_platform_notify(), is called. So far, so good. Now it starts to be "interesting". 6. acpi_find_bridge_device() is used to find the ACPI handle of the given device (which is the PCI root bridge) and executes acpi_pci_find_root_bridge(), among other things, for the given device object. 7. acpi_pci_find_root_bridge() uses the name (sic!) of the given device object to extract the segment and bus numbers of the PCI root bridge and passes them to acpi_get_pci_rootbridge_handle(). 8. acpi_get_pci_rootbridge_handle() browses the list of ACPI PCI root bridges and finds the one that matches the given segment and bus numbers. Its handle is then used to initialize the ACPI handle of the PCI root bridge's device object by acpi_bind_one(). However, this is *exactly* the ACPI handle we started with in step 1. Needless to say, this is quite embarassing, but it may be avoided thanks to commit f3fd0c8 (ACPI: Allow ACPI handles of devices to be initialized in advance), which makes it possible to initialize the ACPI handle of a device before passing it to device_register(). Accordingly, add a new __weak routine, pcibios_root_bridge_prepare(), defaulting to an empty implementation that can be replaced by the interested architecutres (x86 and ia64 at the moment) with functions that will set the root bridge's ACPI handle before its dev member is passed to device_register(). Make both x86 and ia64 provide such implementations of pcibios_root_bridge_prepare() and remove acpi_pci_find_root_bridge() and acpi_get_pci_rootbridge_handle() that aren't necessary any more.

Only dm was explicitly triggering the TP on IO completion. This makes block_bio_complete TP useless for tracers which want to know about bios, and all other bio based drivers skip generating blktrace completion events. This patch makes all bio completions via bio_endio() generate block_bio_complete TP. * Explicit trace_block_bio_complete() invocation removed from dm and the trace point is unexported. * @rq dropped from trace_block_bio_complete(). bios may fly around w/o queue associated. Verifying and accessing the assocaited queue belongs to TP probes. * blktrace now gets both request and bio completions. Make it ignore bio completions if request completion path is happening. This makes all bio based drivers generate blktrace completion events properly and makes the block_bio_complete TP actually useful. v2: With this change, block_bio_complete TP could be invoked on sg commands which have bio's with %NULL bi_bdev. Update TP assignment code to check whether bio->bi_bdev is %NULL before dereferencing.

For the latter two inode events, a pair of events are defined to denote start and end of the operations (the starting one has _start suffix and the one w/o suffix happens after the operation is complete).

If the file already existed, no inode is returned in the reply. This allows ceph to set the created flag in atomic_open so that permissions are properly checked in the case that the file wasn't created by the create call to the mds. To ensure compability with previous kernels, a feature for sending back the inode in the create reply was added, so that the mds will only send back the inode if the client indicates it supports the feature.

Consider the CRUSH rule step chooseleaf firstn 0 type This rule means that replicas will be chosen in a manner such that each chosen leaf's branch will contain a unique instance of . When an object is re-replicated after a leaf failure, if the CRUSH map uses a chooseleaf rule the remapped replica ends up under the bucket that held the failed leaf. This causes uneven data distribution across the storage cluster, to the point that when all the leaves but one fail under a particular bucket, that remaining leaf holds all the data from its failed peers. This behavior also limits the number of peers that can participate in the re-replication of the data held by the failed leaf, which increases the time required to re-replicate after a failure. For a chooseleaf CRUSH rule, the tree descent has two steps: call them the inner and outer descents. If the tree descent down to is the outer descent, and the descent from down to a leaf is the inner descent, the issue is that a down leaf is detected on the inner descent, so only the inner descent is retried. In order to disperse re-replicated data as widely as possible across a storage cluster after a failure, we want to retry the outer descent. So, fix up crush_choose() to allow the inner descent to return immediately on choosing a failed leaf. Wire this up as a new CRUSH tunable. Note that after this change, for a chooseleaf rule, if the primary OSD in a placement group has failed, choosing a replacement may result in one of the other OSDs in the PG colliding with the new primary. This requires that OSD's data for that PG to need moving as well. This seems unavoidable but should be relatively rare. This corresponds to ceph.git commit 88f218181a9e6d2292e2697fc93797d0f6d6e5dc.

The trail field is a ceph_pagelist pointer, and if null it indicates there is no trail. A ceph_pagelist structure contains a length field, and it can legitimately hold value 0. Make use of this to change the interpretation of the "trail" of an osd request so that every osd request has trailing data, it just might have length 0. This means we change the r_trail field in a ceph_osd_request structure from a pointer to a structure that is always initialized. Note that in ceph_osdc_start_request(), the trail pointer (or now address of that structure) is assigned to a ceph message's trail field. Here's why that's still OK (looking at net/ceph/messenger.c): - What would have resulted in a null pointer previously will now refer to a 0-length page list. That message trail pointer is used in two functions, write_partial_msg_pages() and out_msg_pos_next(). - In write_partial_msg_pages(), a null page list pointer is handled the same as a message with 0-length trail, and both result in a "in_trail" variable set to false. The trail pointer is only used if in_trail is true. - The only other place the message trail pointer is used is out_msg_pos_next(). That function is only called by write_partial_msg_pages() and only touches the trail pointer if the in_trail value it is passed is true. Therefore a null ceph_msg->trail pointer is equivalent to a non-null pointer referring to a 0-length page list structure.

Which resulted in all drivers _not_ hodling the lock. Since this is for single-threaded cleanup code, drop the requirement from docs and also drop the lock_grabbing from all _cleanup functions. - Kill the LOCKING section in the doctype, since clearly we're not good enough to keep them up-to-date. And misleading locking documentation is worse than useless (see e.g. the comment in the vmgfx driver about the cleanup mess). And since for most functions the very first line either grabs the lock or has a WARN_ON(!locked) the documentation doesn't really add anything. - Instead put in some effort into explaining the only two special cases a bit better: config_init and config_cleanup are both called from single-threaded setup/teardown code, so don't do any locking. It's the driver's job though to enforce this. - Where lacking, add a WARN_ON(!is_locked). Not many places though, since locking around fbdev setup/teardown is through-roughly screwed up, and so will break almost every single WARN annotation I've tried to add. - Add a drm_modeset_is_locked helper - the Grate Modset Locking Rework will use the compiler to assist in the big reorg by renaming the mode lock, so start encapsulating things. Unfortunately this ended up in the "wrong" header file since it needs the definition of struct drm_device. v2: Drop most WARNS again - we hit them all over the place, mostly in the setup and teardown sequences. And trying to fix it up leads to nice deadlocks, since the locking in the setup code is really inconsistent.

Holding such a crtc lock gives a read-lock on all the other crtc state which can be changed by e.g. a modeset. All non-crtc state is still protected by the mode_config mutex. Callers that need to change modeset state of a crtc (e.g. dpms or set_mode) need to grab both the mode_config lock and nested within any crtc locks. Note that since there can only ever be one holder of the mode_config lock we can grab the subordinate crtc locks in any order (if we need to grab more than one of them). Lockdep can handle such nesting with the mutex_lock_nest_lock call correctly. With this functions that only touch connectors/encoders but not crtcs only need to take the mode_config lock. The biggest such case is the output probing, which means that we can now pageflip and move cursors while the output probe code is reading an edid. Most cases neatly fall into the three buckets: - Only touches connectors and similar output state and so only needs the mode_config lock. - Touches the global configuration and so needs all locks. - Only touches the crtc input side and so only needs the crtc lock. But a few cases that need special consideration: - Load detection which requires a crtc. The mode_config lock already prevents a modeset change, so we can use any unused crtc as we like to do load detection. The only thing to consider is that such temporary state changes don't leak out to userspace through ioctls that only take the crtc look (like a pageflip). Hence the load detect code needs to grab the crtc of any output pipes it touches (but only if it touches state used by the pageflip or cursor ioctls). - Atomic pageflip when moving planes. The first case is sane hw, where planes have a fixed association with crtcs - nothing needs to be done there. More insane^Wflexible hw needs to have plane->crtc mapping which is separately protect with a lock that nests within the crtc lock. If the plane is unused we can just assign it to the current crtc and continue. But if a plane is already in use by another crtc we can't just reassign it. Two solution present themselves: Either go back to a slow-path which takes all modeset locks, potentially incure quite a hefty delay. Or simply disallowing such changes in one atomic pageflip - in general the vblanks of two crtcs are not synced, so there's no sane way to atomically flip such plane changes accross more than one crtc. I'd heavily favour the later approach, going as far as mandating it as part of the ABI of such a new a nuclear pageflip. And if we _really_ want such semantics, we can always get them by introducing another pageflip mutex between the mode_config.mutex and the individual crtc locks. Pageflips crossing more than one crtc would then need to take that lock first, to lock out concurrent multi-crtc pageflips. - Optimized global modeset operations: We could just take the mode_config lock and then lazily lock all crtc which are affected by a modeset operation. This has the advantage that pageflip could continue unhampered on unaffected crtc. But if e.g. global resources like plls need to be reassigned and so affect unrelated crtcs we can still do that - nested locking works in any order. This patch just adds the locks and takes them in drm_modeset_lock_all, no real locking changes yet. v2: Need to initialize the new lock in crtc_init and lock it righ away, for otherwise the modeset_unlock_all below will try to unlock a not-locked mutex.

The goal here is that framebuffer objects can survive outside of the mode_config lock, with just a reference held as protection. The first step to get there is to introduce a special fb_lock which protects fb lookup, creation and destruction, to make them appear atomic. This new fb_lock can nest within the mode_config lock. But the idea is (once the reference counting part is completed) that we only quickly take that fb_lock to lookup a framebuffer and grab a reference, without any other locks involved. vmwgfx is the only driver which does framebuffer lookups itself, also wrap those calls to drm_mode_object_find with the new lock. Also protect the fb_list walking in i915 and omapdrm with the new lock. As a slight complication there's also the list of user-created fbs attached to the file private. The problem now is that at fclose() time we need to walk that list, eventually do a modeset call to remove the fb from active usage (and are required to be able to take the mode_config lock), but in the end we need to grab the new fb_lock to remove the fb from the list. The easiest solution is to add another mutex to protect this per-file list. Currently that new fbs_lock nests within the modeset locks and so appears redudant. But later patches will switch around this sequence so that taking the modeset locks in the fb destruction path is optional in the fastpath. Ultimately the goal is that addfb and rmfb do not require the mode_config lock, since otherwise they have the potential to introduce stalls in the pageflip sequence of a compositor (if the compositor e.g. switches to a fullscreen client or if it enables a plane). But that requires a few more steps and hoops to jump through. Note that framebuffer creation/destruction is now double-protected - once by the fb_lock and in parts by the idr_lock. The later would be unnecessariy if framebuffers would have their own idr allocator. But that's material for another patch (series). v2: Properly initialize the fb->filp_head list in _init, otherwise the newly added WARN to check whether the fb isn't on a fpriv list any more will fail for driver-private objects. v3: Fixup two error-case unlock bugs spotted by Richard Wilbur.

Also add a WARN to drm_mode_object_find since that is now no longer the blessed interface to look up an fb. And add kerneldoc to both functions. This only updates all callsites, but immediately drops the acquired refence again. Hence all callers still rely on the fact that a mode fb can't disappear while they're holding the struct mutex. Subsequent patches will instate proper use of refcounts, and then rework the rmfb and unref code to no longer serialize fb destruction with the mode_config lock. We don't want that since otherwise a compositor might end up stalling for a few frames in rmfb. v2: Don't use kref_get_unless_zero - Greg KH doesn't like that kind of interface.

These framebuffers will be reaped when their assoiciated fb is closed. Now these two cases are set up differently, the framebuffers are on different lists and hence destruction needs to clean up different things. Also, for userspace framebuffers we remove them from any current usage, whereas for internal framebuffers it is assumed that the driver has done this already. Long story short, we need two different ways to cleanup such drivers. Three functions are involved in total: - drm_framebuffer_remove: Convenience function which removes the fb from all active usage and then drops the passed-in reference. - drm_framebuffer_unregister_private: Will remove driver-private framebuffers from relevant lists and drop the corresponding references. Should be called for driver-private framebuffers before dropping the last reference (or like for a lot of the drivers where the fbdev is embedded someplace else, before doing the cleanup manually). - drm_framebuffer_cleanup: Final cleanup for both classes of fbs, should be called by the driver's ->destroy callback once the last reference is gone. This patch just rolls out the new interfaces and updates all drivers (by adding calls to drm_framebuffer_unregister_private at all the right places)- no functional changes yet. Follow-on patches will move drm core code around and update the lifetime management for framebuffers, so that we are no longer required to keep framebuffers alive by locking mode_config.mutex. I've also updated the kerneldoc already. vmwgfx seems to again be a bit special, at least I haven't figured out how the fbdev support in that driver works. It smells like it's external though. v2: The i915 driver creates another private framebuffer in the load-detect code. Adjust its cleanup code, too.

This allows the description of a display via its supported timing parameters. Also, add helper functions to convert from display timings to a generic videomode structure. The struct display_timing specifies all needed parameters to describe the signal properties of a display in one mode. This includes - ranges for signals that may have min-, max- and typical values - single integers for signals that can be on, off or are ignored - booleans for signals that are either on or off As a display may support multiple modes like this, a struct display_timings is added, that holds all given struct display_timing pointers and declares the native mode of the display. Although a display may state that a signal can be in a range, it is driven with fixed values that indicate a videomode. Therefore graphic drivers don't need all the information of struct display_timing, but would generate a videomode from the given set of supported signal timings and work with that. The video subsystems all define their own structs that describe a mode and work with that (e.g. fb_videomode or drm_display_mode). To slowly replace all those various structures and allow code reuse across those subsystems, add struct videomode as a generic description. This patch only includes the most basic fields in struct videomode. All missing fields that are needed to have a really generic video mode description can be added at a later stage.
