The call to mmc_request_done() can schedule, so it must not be called from irq context. Wake the irq thread if it needs to be called, and let its existing logic do its work.

2023-06-12mmc: sdhci-msm: Disable broken 64-bit DMA on MSM8916Stephan Gerhold1-0/+3
While SDHCI claims to support 64-bit DMA on MSM8916 it does not seem to be properly functional. It is not immediately obvious because SDHCI is usually used with IOMMU bypassed on this SoC, and all physical memory has 32-bit addresses. But when trying to enable the IOMMU it quickly fails with an error such as the following: arm-smmu 1e00000.iommu: Unhandled context fault: fsr=0x402, iova=0xfffff200, fsynr=0xe0000, cbfrsynra=0x140, cb=3 mmc1: ADMA error: 0x02000000 mmc1: sdhci: ============ SDHCI REGISTER DUMP =========== mmc1: sdhci: Sys addr: 0x00000000 | Version: 0x00002e02 mmc1: sdhci: Blk size: 0x00000008 | Blk cnt: 0x00000000 mmc1: sdhci: Argument: 0x00000000 | Trn mode: 0x00000013 mmc1: sdhci: Present: 0x03f80206 | Host ctl: 0x00000019 mmc1: sdhci: Power: 0x0000000f | Blk gap: 0x00000000 mmc1: sdhci: Wake-up: 0x00000000 | Clock: 0x00000007 mmc1: sdhci: Timeout: 0x0000000a | Int stat: 0x00000001 mmc1: sdhci: Int enab: 0x03ff900b | Sig enab: 0x03ff100b mmc1: sdhci: ACmd stat: 0x00000000 | Slot int: 0x00000000 mmc1: sdhci: Caps: 0x322dc8b2 | Caps_1: 0x00008007 mmc1: sdhci: Cmd: 0x0000333a | Max curr: 0x00000000 mmc1: sdhci: Resp[0]: 0x00000920 | Resp[1]: 0x5b590000 mmc1: sdhci: Resp[2]: 0xe6487f80 | Resp[3]: 0x0a404094 mmc1: sdhci: Host ctl2: 0x00000008 mmc1: sdhci: ADMA Err: 0x00000001 | ADMA Ptr: 0x0000000ffffff224 mmc1: sdhci_msm: ----------- VENDOR REGISTER DUMP ----------- mmc1: sdhci_msm: DLL sts: 0x00000000 | DLL cfg: 0x60006400 | DLL cfg2: 0x00000000 mmc1: sdhci_msm: DLL cfg3: 0x00000000 | DLL usr ctl: 0x00000000 | DDR cfg: 0x00000000 mmc1: sdhci_msm: Vndr func: 0x00018a9c | Vndr func2 : 0xf88018a8 Vndr func3: 0x00000000 mmc1: sdhci: ============================================ mmc1: sdhci: fffffffff200: DMA 0x0000ffffffffe100, LEN 0x0008, Attr=0x21 mmc1: sdhci: fffffffff20c: DMA 0x0000000000000000, LEN 0x0000, Attr=0x03 Looking closely it's obvious that only the 32-bit part of the address (0xfffff200) arrives at the SMMU, the higher 16-bit (0xffff...) get lost somewhere. This might not be a limitation of the SDHCI itself but perhaps the bus/interconnect it is connected to, or even the connection to the SMMU. Work around this by setting SDHCI_QUIRK2_BROKEN_64_BIT_DMA to avoid using 64-bit addresses.

2023-05-09mmc: block: ensure error propagation for non-blkChristian Loehle1-0/+5
Requests to the mmc layer usually come through a block device IO. The exceptions are the ioctl interface, RPMB chardev ioctl and debugfs, which issue their own blk_mq requests through blk_execute_rq and do not query the BLK_STS error but the mmcblk-internal drv_op_result. This patch ensures that drv_op_result defaults to an error and has to be overwritten by the operation to be considered successful. The behavior leads to a bug where the request never propagates the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged) and thus may assume that their call executed successfully when it did not. While always checking the blk_execute_rq return value would be advised, let's eliminate the error by always setting drv_op_result as -EIO to be overwritten on success (or other error) Fixes: 614f0388f580 ("mmc: block: move single ioctl() commands to block requests") Signed-off-by: Christian Loehle <cloehle@hyperstone.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/59c17ada35664b818b7bd83752119b2d@hyperstone.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
