To compile this driver as a module, choose M here: the module will be called nvhost-vi. config TEGRA_GRHOST_DEFAULT_TIMEOUT depends on TEGRA_GRHOST int "Default timeout for submits" default 10000 help Default timeout for jobs in milliseconds. Set to zero for no timeout. config TEGRA_GRHOST_SYNC depends on TEGRA_GRHOST bool "Tegra host synchronization objects" default y select SYNC help Add tegra host backend for the cross driver synchronization framework. Allows creating sync fence file descriptors from Tegra host syncpoints. config TEGRA_DC tristate "Tegra Display Contoller" depends on ARCH_TEGRA && TEGRA_GRHOST && I2C select BACKLIGHT_CLASS_DEVICE select FB_MODE_HELPERS help Tegra display controller support. config TEGRA_DC_CMU bool "Tegra Color Management Unit" default y help Say Y here to enable Tegra color management unit. Enabled by default to support color correction for panels. It is used to make the representation of color match accross displays. config TEGRA_DC_WIN_H bool config TEGRA_MIPI_CAL bool default y config TEGRA_DC_SCAN_COLUMN bool default y if ARCH_TEGRA_12x_SOC config TEGRA_DC_BLENDER_GEN2 bool default y config TEGRA_DC_BLENDER_DEPTH bool default y if ARCH_TEGRA_12x_SOC config TEGRA_DC_BLOCK_LINEAR bool default y if ARCH_TEGRA_12x_SOC config TEGRA_DC_INTERLACE bool default y if ARCH_TEGRA_12x_SOC config TEGRA_DC_64BIT_SUPPORT bool help T12x LPAE support in dc driver config TEGRA_DC_LOW_LATENCY_CURSOR bool default y if ARCH_TEGRA_12x_SOC config TEGRA_DC_CLOCK_GEN2 bool default y if ARCH_TEGRA_12x_SOC help T12x redefined pll usages for pll_d and pll_d2. config TEGRA_SD_GEN2 bool default y config TEGRA_DC_TEMPORAL_DITHER bool default y config FB_TEGRA tristate "Tegra Framebuffer driver" depends on TEGRA_DC && FB = y select FB_CFB_FILLRECT select FB_CFB_COPYAREA select FB_CFB_IMAGEBLIT default FB && !ADF help Framebuffer device support for the Tegra display controller. config ADF_TEGRA tristate "Tegra ADF driver" depends on TEGRA_DC && ADF default ADF select ADF_FBDEV select VIDEOBUF2_DMA_CONTIG help ADF device support for the Tegra display controller. config TEGRA_DC_EXTENSIONS bool "Tegra Display Controller Extensions" depends on TEGRA_DC default y help This exposes support for extended capabilities of the Tegra display controller to userspace drivers. config TEGRA_NVMAP bool "Tegra GPU memory management driver (nvmap)" select ARM_DMA_USE_IOMMU if IOMMU_API select DMA_SHARED_BUFFER default y help Say Y here to include the memory management driver for the Tegra GPU, multimedia and display subsystems config NVMAP_HIGHMEM_ONLY bool "Use only HIGHMEM for nvmap" depends on TEGRA_NVMAP && IOMMU_API && HIGHMEM help Say Y here to restrict nvmap system memory allocations (both physical system memory and IOVMM) to just HIGHMEM pages. config NVMAP_PAGE_POOLS bool "Use page pools to reduce allocation overhead" depends on TEGRA_NVMAP default y help say Y here to reduce the alloction overhead, which is significant for uncached, writecombine and inner cacheable memories as it involves changing page attributes during every allocation per page and flushing cache. Alloc time is reduced by allcoating the pages ahead and keeping them aside. The reserved pages would be released when system is low on memory and acquired back during release of memory. config NVMAP_PAGE_POOL_DEBUG bool "Debugging for page pools" depends on NVMAP_PAGE_POOLS help Say Y here to include some debugging info in the page pools. This adds a bit of unnecessary overhead so only enable this is you suspect there is an issue with the nvmap page pools. config NVMAP_PAGE_POOLS_INIT_FILLUP bool "Fill up page pools during page pools init" depends on NVMAP_PAGE_POOLS default y help Say Y here to fill up the page pools during page pool init time. This helps in faster alloctions right from the early alloction requests. Page pools fill up during init would increase the boot time. If increase in boot time is not acceptable, keep this option disabled. config NVMAP_PAGE_POOLS_INIT_FILLUP_SIZE depends on NVMAP_PAGE_POOLS_INIT_FILLUP hex "Amount of memory to fill up page pools with during bootup in MB" default 0x64 config NVMAP_PAGE_POOL_SIZE depends on NVMAP_PAGE_POOLS hex "Page pool size in pages" default 0x0 config NVMAP_CACHE_MAINT_BY_SET_WAYS bool "Enable cache maintenance by set/ways" depends on TEGRA_NVMAP help Say Y here to reduce cache maintenance overhead by MVA. This helps in reducing cache maintenance overhead in the systems, where inner cache includes only L1. For the systems, where inner cache includes L1 and L2, keep this option disabled. config NVMAP_CACHE_MAINT_BY_SET_WAYS_ON_ONE_CPU bool "Perform cache maint on one cpu only" depends on TEGRA_NVMAP && NVMAP_CACHE_MAINT_BY_SET_WAYS help Say Y here to avoid cache maint on all CPU's during inner cache maint by set/ways. When L1 and L2 are inner caches, cache maint on one CPU is enough. When L1 is inner and L2 is outer, cache maint on all CPU's is necessary during L1 cache maint by set/ways. config NVMAP_OUTER_CACHE_MAINT_BY_SET_WAYS bool "Enable outer cache maintenance by set/ways" depends on TEGRA_NVMAP help Say Y here if you want to optimize cache maintenance for ranges bigger than size of outer cache. This option has no effect on system without outer cache. config NVMAP_DMABUF_STASH bool "Enable stashing of IOVA maps with dmabuf" depends on TEGRA_NVMAP default y help Set to Y if you would like nvmap to stash maps when using dma bufs. This will speed up remapping of the same handle at the cost of using more IOVA space. config NVMAP_DMABUF_STASH_STATS bool "Enable stat tracking on the stash" depends on NVMAP_DMABUF_STASH help Say Y to enable tracking of basic cache statistics on the dmabuf stash. This adds some overhead but should be very useful for debugging memory leaks. config NVMAP_FORCE_ZEROED_USER_PAGES bool "Only alloc zeroed pages for user space" depends on TEGRA_NVMAP default y help Say Y here to force zeroing of pages allocated for user space. This avoids leaking kernel secure data to user space. This can add significant overhead to allocation operations depending on the allocation size requested. config NVMAP_USE_CMA_FOR_CARVEOUT bool "Use CMA memory for carveouts" depends on TEGRA_NVMAP help Say Y here to reserve carveout memory using CMA API. CMA reserved memory can be used by applications when it is not in use by the device that reserved it. config NVMAP_FD_START hex "FD number to start allocation from" depends on TEGRA_NVMAP default 0x400 help NvMap handles are represented with FD's in the user processes. To avoid Linux FD usage limitations, NvMap allocates FD starting from this number. config NVMAP_DEFER_FD_RECYCLE bool "Defer FD recycle" depends on TEGRA_NVMAP help Say Y here to enable deferred FD recycle. A released nvmap handle would release memory and FD. This FD can be reused immediately for subsequent nvmap allocation req in the same process. Any buggy code in client process that continues to use FD of released allocation would continue to use new allocation and can lead to undesired consequences, which can be hard to debug. Enabling this option would defer recycling FD for longer time and allows debugging incorrect FD references by clients by returning errors for the accesses that occur after handle/FD release. config NVMAP_DEFER_FD_RECYCLE_MAX_FD hex "FD number to start free FD recycle" depends on NVMAP_DEFER_FD_RECYCLE default 0x8000 help Once last allocated FD reaches this number, allocation of subsequent FD's start from NVMAP_START_FD. config TEGRA_DSI bool "Enable DSI panel." help Say Y here to enable the DSI panel. config TEGRA_DSI2EDP_TC358767 bool "Enable DSI2EDP TC358767 bridge." help Say Y here to enable the DSI2EDP TOSHIBA 358767 adapter. config TEGRA_DSI2EDP_SN65DSI86 bool "Enable DSI2EDP SN65DSI86 bridge." help Say Y here to enable the DSI2EDP TI SN65DSI86 adapter. config TEGRA_DP bool "Enable eDP panel." default n help Say Y here to enable eDP panel. config TEGRA_LVDS bool "Enable LVDS panel." default n help Say Y here to enable LVDS panel. config TEGRA_NVSR bool "Enable NVSR support." default n help Say Y here to enable NVSR support. config NVMAP_CONVERT_CARVEOUT_TO_IOVMM bool "Convert carveout to IOVMM" depends on TEGRA_NVMAP && IOMMU_API default y help Say Y here to force to convert carveout memory requests to I/O virtual memory requests. config TEGRA_NVHDCP bool "Support NVHDCP content protection on HDMI" help Say Y here to support NVHDCP upstream and downstream protocols, this requires a correctly fused chip to negotiate keys. config TEGRA_HDMI_74MHZ_LIMIT bool "Support only up to 74.25 MHz HDMI pixel frequency" help Say Y here to make kernel report only low bandwidth modes. Useful only for boards which can't deliver 148.50 MHz. endif config TEGRA_CAMERA bool "Enable support for tegra camera/isp hardware" depends on ARCH_TEGRA default y help Enables support for the Tegra camera interface If unsure, say Y
