2016-06-22mmc: sdhci: handle command timeout after transfer complete interruptNicolas Serafini
On a tegra3 platform with Hynix eMMC we can observe that sometimes we receive a command timeout after a transfer complete interrupt on a multiple block read request. Here is the output using MMC_DEBUG and ftrace. When it works: tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 0 enabled=1 tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 52000000 enabled=0 __mmc_start_req: mmc0: starting CMD18 arg 00a73044 flags 000000b5 __mmc_start_req: mmc0: blksz 512 blocks 2 flags 00000200 tsac 150 ms nsac 1000 __mmc_start_req: mmc0: CMD12 arg 00000000 flags 0000049d sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000001 sdhci_finish_command: sdhci_finish_command:1075 sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000002 sdhci_tasklet_finish: sdhci_tasklet_finish:2064 When we have the error: tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 0 enabled=1 tegra_sdhci_set_clock: tegra_sdhci_set_clock mmc0 52000000 enabled=0 __mmc_start_req: mmc0: starting CMD18 arg 00a63d12 flags 000000b5 __mmc_start_req: mmc0: blksz 512 blocks 2 flags 00000200 tsac 150 ms nsac 1000 __mmc_start_req: mmc0: CMD12 arg 00000000 flags 0000049d sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000001 sdhci_finish_command: sdhci_finish_command:1075 sdhci_irq: sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00018000 ------NOW THE REQUEST BLOCK UNTIL TIMEOUT------ We can see that when it works the multiple read blocks command stopped by the CMD12 receive two interrupts. The first is the Transfer complete interrupt (SDHCI_INT_RESPONSE) and just after the Block Gap Event interrupt (SDHCI_INT_DATA_END). In this case the command is finished and the data is finished too. In the bad case instead of receiving SDHCI_INT_DATA_END we receive a command timeout error (SDHCI_INT_TIMEOUT) but command was already finished by the SDHCI_INT_RESPONSE so not more command is waiting and the driver wait until the timeout timer end because this case is not managed.

2016-03-22ARM: 8429/1: disable GCC SRA optimizationArd Biesheuvel
While working on the 32-bit ARM port of UEFI, I noticed a strange corruption in the kernel log. The following snprintf() statement (in drivers/firmware/efi/efi.c:efi_md_typeattr_format()) snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]", was producing the following output in the log: | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | | | | |UC] |RUN| | | | | | | |UC] As it turns out, this is caused by incorrect code being emitted for the string() function in lib/vsprintf.c. The following code if (!(spec.flags & LEFT)) { while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } } for (i = 0; i < len; ++i) { if (buf < end) *buf = *s; ++buf; ++s; } while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } when called with len == 0, triggers an issue in the GCC SRA optimization pass (Scalar Replacement of Aggregates), which handles promotion of signed struct members incorrectly. This is a known but as yet unresolved issue. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular case, it is causing the second while loop to be executed erroneously a single time, causing the additional space characters to be printed. So disable the optimization by passing -fno-ipa-sra.

The Ixora carrier board has a few MXM3 pins repurposed as follows: Functionality MXM3 Pin LED4_RED 146 LED4_GREEN 162 LED5_RED 156 LED5_GREEN 152 PCIE1_WDISABLE_N 144 SW3 160 UART2_3_RS232_FOFF_N 164 This patch allows uncommenting an IXORA define in the board header file in order to make use of those repurposed pins. Please note that those pins are usually used for the 8-bit MMC/SD slot aka Apalis MMC1 and the SDHCI controller/driver unfortunately changes the output driver behaviour in a way preventing any regular GPIO use. This patch therefore explicitly does not register the SDHCI driver on this controller instance in the Ixora case to avoid this.

It is fully legal for a controller to start handling busy-end interrupt before it has signaled that the command has completed. So make sure we do things in the proper order, Or it results that command interrupt is ignored so it can cause unexpected operations. This is founded at some toshiba emmc with the bellow warning. "mmc0: Got command interrupt 0x00000001 even though no command operation was in progress."

2015-10-09mmc: sdhci-pci: add runtime pm supportAdrian Hunter
Ths patch allows runtime PM for sdhci-pci, runtime suspending after inactivity of 50ms and ensuring runtime resume before SDHC registers are accessed. During runtime suspend, interrupts are masked. The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.

2015-09-26apalis/colibri_t30: usb: fix performance regressionMarcel Ziswiler
Unfortunately that utmi_phy_remotewake_detected() function gets called one too many times even quite continuously during data transfers and putting an mdelay() in there has a rather adverse effect on the overall system performance including of course degrading USB transfer speeds. Moving the system lock-up avoidance hack further down into the if clause improves the performance again as this typically is only ever evaluated once upon actually plugging something in behind a hub. This fixes a performance regression introduced by the following commit: apalis/colibri_t30: usb: fix low-speed issue hack 629b91fa046df5213ed3312d2e2b8683e6bdd70c
2015-08-31apalis/colibri_t30: Add comments about i2s pin muxing/operationMarcel Ziswiler
Add a comment about DAP FS pin mux requiring INPUT when operating as I2S slave. Add a comment about DAP SCLK requiring INPUT even when operating as I2S master. Add a comment about is_i2s_master in the platform data meaning T30 SoC is I2S master.
2015-06-12colibri_t20: hack: prevent rare boot lock-upMarcel Ziswiler
A customer reported rare boot lock-ups every odd 500 software reboot cycle. This patch removes the display clock initialisation from the early clock initialisation as the boot loader anyway already initialised the same.
2015-06-10colibri_t20/t30: net: usb: asix: ethernet mac address handlingMarcel Ziswiler
Revise Ethernet MAC address assignment: should now handle up to two instances of custom user MACs (2nd one with a 0x100000 offset). This way customer does not have to worry about NVM on a secondary Ethernet on the carrier board and still gets a valid official MAC address from us (e.g. analogous to how we did it on our Protea carrier board). Please note that instead of defaulting to the default ASIX MAC address if no valid one is encountered this driver now generates a random one pre-fixed with the ASIX OUI.

2015-06-03colibri_t20: improve pmic rtc accuracyMarcel Ziswiler
It looks like our crystal load capacitance is way off as we just copied NVIDIA's default setting being the lowest possible 1.5 pF due to their boards having 20 pF external caps while our hardware does not have any external caps assembled and we should use the highest 12.5 pF setting.
