2021-09-03mmc: mmc_spi: replace flush_kernel_dcache_page with flush_dcache_pageChristoph Hellwig1-1/+1
Pages passed to block drivers can be mapped page cache pages, so we must use flush_dcache_page here instead of the more limited flush_kernel_dcache_page that is intended for highmem pages only.

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).

This reverts commit 419dd626e357e89fc9c4e3863592c8b38cfe1571. It turned out that the change from the reverted commit breaks the ACPI based rpi's because it causes the 100Mhz max clock to be overridden to the return from sdhci_iproc_get_max_clock(), which is 0 because there isn't a OF/DT based clock device.

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: 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.

Make 'struct mmc_request' contain a pointer to the request's 'struct bio_crypt_ctx' directly, instead of extracting a 32-bit DUN from it which is a cqhci-crypto specific detail. This keeps the cqhci crypto specific details in the cqhci module, and it makes mmc_core and mmc_block ready for MMC crypto hardware that accepts the DUN and/or key in a way that is more flexible than that which will be specified by the eMMC v5.2 standard. Exynos SoCs are an example of such hardware, as their inline encryption hardware takes keys directly (it has no concept of keyslots) and supports 128-bit DUNs. Note that the 32-bit DUN length specified by the standard is very restrictive, so it is likely that more hardware will support longer DUNs despite it not following the standard. Thus, limiting the scope of the 32-bit DUN assumption to the place that actually needs it is warranted.
