ARCH_RENESAS is a stronger condition than (ARM || ARM64). If ARCH_RENESAS is enabled, (ARM || ARM64) is met as well. What is worse, the first depends on line prevents COMPILE_TEST from enabling this driver. It should be removed. Signed-off-by:

Not all archs define reads* and writes*. Switch to ioread*_rep and friends which is defined everywhere, so we can enable COMPILE_TEST after that. Signed-off-by:

To get an usdhc Apacer and some ATP SD cards work reliable, CMD23 needs to be disabled. This has been tested on i.MX6 (sdhci-esdhc) and rk3288 (dw_mmc-rockchip).

mmc_blk_alloc_req() is supposed to return error pointers but there is one path where we forget to set the error code and accidentally return NULL. The callers are not expecting that and will have a NULL pointer dereference. Fixes: 41e3efd0 ("mmc: block: Simplify cleaning up the queue") Signed-off-by:

mmc_test disables the command queue because none of the tests use the command queue. However the Reset Test will re-enable it, so disable it in that case too. Fixes: 9d4579a8 ("mmc: mmc_test: Disable Command Queue while mmc_test is used") Signed-off-by:

mmc_test now uses mmc_start_request() to test sending commands during "ongoing" asynchronous transfers, i.e. tests: Commands during non-blocking read - use Set Block Count (CMD23) Commands during non-blocking write - use Set Block Count (CMD23) mmc_start_request() was not initializing cmd_completion, but cmd_completion is used by "ongoing" transfers, so move initialization of cmd_completion into making mmc_start_request().

Calling getnstimeofday() can suffer from time jumps and from the y2038 overflow, so it is not appropriate here. Using ktime_get_ts64() solves both problems. Using ktime_get() with ktime_t timestamps would also work, but it seems that we mainly want to print the times as seconds+nanoseconds, so it would require an extra division in the output.

There are only a few things the recovery needs to do. Primarily, it just needs to: Determine the number of bytes transferred Get the card back to transfer state Determine whether to retry There are also a couple of additional features: Reset the card before the last retry Read one sector at a time The legacy code spent much effort analyzing command errors, but commands fail fast, so it is simpler just to give all command errors the same number of retries.

Set a 10 second timeout for polling write request busy state. Note, mmc core is setting a 3 second timeout for SD cards, and SDHCI has long had a 10 second software timer to timeout the whole request, so 10 seconds should be ample. Signed-off-by:

Adrian Hunter authored
According to the specification, total access time is derived from both TAAC and NSAC, which means the timeout should add both timeout_ns and timeout_clks. Host drivers do that, so make the block driver do that too. Signed-off-by:

The card is required to return to transfer state. Since that is the state required to start another transfer, check for that state instead of programming state. Signed-off-by:
