2021-10-21blk-crypto: rename blk_keyslot_manager to blk_crypto_profileEric Biggers2-19/+23
blk_keyslot_manager is misnamed because it doesn't necessarily manage keyslots. It actually does several different things: - Contains the crypto capabilities of the device. - Provides functions to control the inline encryption hardware. Originally these were just for programming/evicting keyslots; however, new functionality (hardware-wrapped keys) will require new functions here which are unrelated to keyslots. Moreover, device-mapper devices already (ab)use "keyslot_evict" to pass key eviction requests to their underlying devices even though device-mapper devices don't have any keyslots themselves (so it really should be "evict_key", not "keyslot_evict"). - Sometimes (but not always!) it manages keyslots. Originally it always did, but device-mapper devices don't have keyslots themselves, so they use a "passthrough keyslot manager" which doesn't actually manage keyslots. This hack works, but the terminology is unnatural. Also, some hardware doesn't have keyslots and thus also uses a "passthrough keyslot manager" (support for such hardware is yet to be upstreamed, but it will happen eventually). Let's stop having keyslot managers which don't actually manage keyslots. Instead, rename blk_keyslot_manager to blk_crypto_profile. This is a fairly big change, since for consistency it also has to update keyslot manager-related function names, variable names, and comments -- not just the actual struct name. However it's still a fairly straightforward change, as it doesn't change any actual functionality.

circuit To reset standard tuning circuit completely, after clear ESDHC_MIX_CTRL_EXE_TUNE, also need to clear bit buffer_read_ready, this operation will finally clear the USDHC IP internal logic flag execute_tuning_with_clr_buf, make sure the following normal data transfer will not be impacted by standard tuning logic used before. Find this issue when do quick SD card insert/remove stress test. During standard tuning prodedure, if remove SD card, USDHC standard tuning logic can't clear the internal flag execute_tuning_with_clr_buf. Next time when insert SD card, all data related commands can't get any data related interrupts, include data transfer complete interrupt, data timeout interrupt, data CRC interrupt, data end bit interrupt. Always trigger software timeout issue. Even reset the USDHC through bits in register SYS_CTRL (0x2C, bit28 reset tuning, bit26 reset data, bit 25 reset command, bit 24 reset all) can't recover this. From the user's point of view, USDHC stuck, SD can't be recognized any more.

Intel Merrifield platform had been converted to use ACPI enumeration. However, the driver missed an update to retrieve card detect GPIO. Fix it here. Unfortunately we can't rely on CD GPIO state because there are two different PCB designs in the wild that are using the opposite card detection sense and there is no way to distinguish those platforms, that's why ignore CD GPIO completely and use it only as an event.

The fix we agreed on in the end is to make this symbol selected by any driver using it, and then building it even for non-Arm platforms with CONFIG_COMPILE_TEST. To make this work on all architectures, the drivers/firmware/Kconfig file needs to be included for all architectures to make the symbol itself visible. In a separate discussion, we found that a sound driver patch that is pending for v5.16 needs the same change to include this Kconfig file, so the easiest solution seems to have my Kconfig rework included in v5.15.

Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.

2021-10-06mmc: meson-gx: do not use memcpy_to/fromio for dram-access-quirkNeil Armstrong1-14/+59
The memory at the end of the controller only accepts 32bit read/write accesses, but the arm64 memcpy_to/fromio implementation only uses 64bit (which will be split into two 32bit access) and 8bit leading to incomplete copies to/from this memory when the buffer is not multiple of 8bytes. Add a local copy using writel/readl accesses to make sure we use the right memory access width. The switch to memcpy_to/fromio was done because of 285133040e6c ("arm64: Import latest memcpy()/memmove() implementation"), but using memcpy worked before since it mainly used 32bit memory acceses.

2021-09-06mmc: dw_mmc: Only inject fault before done/errorVincent Whitchurch1-3/+12
The fault injection function can set EVENT_DATA_ERROR but skip the setting of ->data_status to an error status if it hits just after a data over interrupt. This confuses the tasklet which can later end up triggering the WARN_ON(host->cmd || ..) in dw_mci_request_end() since dw_mci_data_complete() would return success. Prevent the fault injection function from doing this since this is not a real case, and ensure that the fault injection doesn't race with a real error either.

2021-09-03mmc: JZ4740: remove the flush_kernel_dcache_page call in jz4740_mmc_read_dataChristoph Hellwig1-4/+0
Patch series "_kernel_dcache_page fixes and removal". While looking to convert the block layer away from kmap_atomic towards kmap_local_page and prefeably the helpers that abstract it away I noticed that a few block drivers directly or implicitly call flush_kernel_dcache_page before kunmapping a page that has been written to. flush_kernel_dcache_page is documented to to be used in such cases, but flush_dcache_page is actually required when the page could be in the page cache and mapped to userspace, which is pretty much always the case when kmapping an arbitrary page. Unfortunately the documentation doesn't exactly make that clear, which lead to this misused. And it turns out that only the copy_strings / copy_string_kernel in the exec code were actually correct users of flush_kernel_dcache_page, which is why I think we should just remove it and eat the very minor overhead in exec rather than confusing poor driver writers. This patch (of 6): MIPS now implements flush_kernel_dcache_page (as an alias to flush_dcache_page).

2021-08-25mmc: core: Return correct emmc response in case of ioctl errorNishad Kamdar1-2/+1
When a read/write command is sent via ioctl to the kernel, and the command fails, the actual error response of the emmc is not sent to the user. IOCTL read/write tests are carried out using commands 17 (Single BLock Read), 24 (Single Block Write), 18 (Multi Block Read), 25 (Multi Block Write) The tests are carried out on a 64Gb emmc device. All of these tests try to access an "out of range" sector address (0x09B2FFFF). It is seen that without the patch the response received by the user is not OUT_OF_RANGE error (R1 response 31st bit is not set) as per JEDEC specification. After applying the patch proper response is seen. This is because the function returns without copying the response to the user in case of failure. This patch fixes the issue. Hence, this memcpy is required whether we get an error response or not. Therefor it is moved up from the current position up to immediately after we have called mmc_wait_for_req(). The test code and the output of only the CMD17 is included in the commit to limit the message length. CMD17 (Test Code Snippet): ========================== printf("Forming CMD%d\n", opt_idx); /* single block read */ cmd.blksz = 512; cmd.blocks = 1; cmd.write_flag = 0; cmd.opcode = 17; //cmd.arg = atoi(argv[3]); cmd.arg = 0x09B2FFFF; /* Expecting response R1B */ cmd.flags = MMC_RSP_SPI_R1 | MMC_RSP_R1 | MMC_CMD_ADTC; memset(data, 0, sizeof(__u8) * 512); mmc_ioc_cmd_set_data(cmd, data); printf("Sending CMD%d: ARG[0x%08x]\n", opt_idx, cmd.arg); if(ioctl(fd, MMC_IOC_CMD, &cmd)) perror("Error"); printf("\nResponse: %08x\n", cmd.response[0]); CMD17 (Output without patch): ============================= test@test-LIVA-Z:~$ sudo ./mmc cmd_test /dev/mmcblk0 17 Entering the do_mmc_commands:Device: /dev/mmcblk0 nargs:4 Entering the do_mmc_commands:Device: /dev/mmcblk0 options[17, 0x09B2FFF] Forming CMD17 Sending CMD17: ARG[0x09b2ffff] Error: Connection timed out Response: 00000000 (Incorrect response) CMD17 (Output with patch): ========================== test@test-LIVA-Z:~$ sudo ./mmc cmd_test /dev/mmcblk0 17 [sudo] password for test: Entering the do_mmc_commands:Device: /dev/mmcblk0 nargs:4 Entering the do_mmc_commands:Device: /dev/mmcblk0 options[17, 09B2FFFF] Forming CMD17 Sending CMD17: ARG[0x09b2ffff] Error: Connection timed out Response: 80000900 (Correct OUT_OF_ERROR response as per JEDEC specification) Signed-off-by: Nishad Kamdar <nishadkamdar@gmail.com> Reviewed-by: Avri Altman <avri.altman@wdc.com> Link: https://lore.kernel.org/r/20210824191726.8296-1-nishadkamdar@gmail.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2021-08-24mmc: usdhi6rol0: Implement card_busy functionMårten Lindahl1-0/+10
When switching card voltage to UHS voltage the mmc framework tries to check the card busy signal, meaning the card pulling DAT0 line low, before the switch is made. Drivers that does not implement the card_busy function will manage to do the switch anyway, but the framework will print a warning about not being able to verify the voltage signal. Implement card_busy function.

2021-08-24mmc: sdhci: Correct the tuning command handle for PIO modeHaibo Chen1-2/+8
If sdhci use PIO mode, and use mmc_send_tuning() to send the tuning command, system will stuck because of the storm irq of sdhci. For PIO mode, use mmc_send_tuning(), it will trigger buffer_read_ready interrupt and data transfer complete interrupt. In current code logic, it will directly return in sdhci_data_irq, can not call the sdhci_transfer_pio(). So the buffer_read_ready interrupt storm happen. So for standard tuning method, need to exclude this case.

2021-08-24mmc: moxart: Fix issue with uninitialized dma_slave_configTony Lindgren1-0/+1
Depending on the DMA driver being used, the struct dma_slave_config may need to be initialized to zero for the unused data. For example, we have three DMA drivers using src_port_window_size and dst_port_window_size. If these are left uninitialized, it can cause DMA failures. For moxart, this is probably not currently an issue but is still good to fix though.

2021-08-24mmc: sdhci-msm: Use maximum possible data timeout valueSahitya Tummala1-0/+3
The Qcom SD controller defines the usage of 0xF in data timeout counter register (0x2E) which is actually a reserved bit as per specification. This would result in maximum of 21.26 secs timeout value. Some SDcard taking more time than 2.67secs (timeout value corresponding to 0xE) and with that observed data timeout errors. So increasing the timeout value to max possible timeout.

2021-08-24mmc: rtsx_pci: Fix long reads when clock is prescaledThomas Hebb1-13/+23
For unexplained reasons, the prescaler register for this device needs to be cleared (set to 1) while performing a data read or else the command will hang. This does not appear to affect the real clock rate sent out on the bus, so I assume it's purely to work around a hardware bug. During normal operation, the prescaler is already set to 1, so nothing needs to be done. However, in "initial mode" (which is used for sub-MHz clock speeds, like the core sets while enumerating cards), it's set to 128 and so we need to reset it during data reads. We currently fail to do this for long reads. This has no functional affect on the driver's operation currently written, as the MMC core always sets a clock above 1MHz before attempting any long reads. However, the core could conceivably set any clock speed at any time and the driver should still work, so I think this fix is worthwhile. I personally encountered this issue while performing data recovery on an external chip. My connections had poor signal integrity, so I modified the core code to reduce the clock speed. Without this change, I saw the card enumerate but was unable to actually read any data. Writes don't seem to work in the situation described above even with this change (and even if the workaround is extended to encompass data write commands). I was not able to find a way to get them working.
