From: Alim Akhtar <alim.akhtar@xxxxxxxxxxx> Hardware locked error set when the dw_mmc controller cannot load a command issued by software. When software sets the start_cmd bit in the CMD register, the controller tries to load the command. If the command buffer is already filled with a command, this error is raised. Currently driver does not handle HLE interrupt, which results in a system hang. HLE can be simulated by quickly inserting and removing sd card in card slot (30 ~ 40 times in say 20 secs) Reviewed-by: Doug Anderson <dianders@xxxxxxxxxxxx> Signed-off-by: Alim Akhtar <alim.akhtar@xxxxxxxxxxx> --- drivers/mmc/host/dw_mmc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/mmc/host/dw_mmc.c b/drivers/mmc/host/dw_mmc.c index 0a6a512..24b4a52 100644 --- a/drivers/mmc/host/dw_mmc.c +++ b/drivers/mmc/host/dw_mmc.c @@ -44,7 +44,7 @@ SDMMC_INT_HTO | SDMMC_INT_SBE | \ SDMMC_INT_EBE) #define DW_MCI_CMD_ERROR_FLAGS (SDMMC_INT_RTO | SDMMC_INT_RCRC | \ - SDMMC_INT_RESP_ERR) + SDMMC_INT_RESP_ERR | SDMMC_INT_HLE) #define DW_MCI_ERROR_FLAGS (DW_MCI_DATA_ERROR_FLAGS | \ DW_MCI_CMD_ERROR_FLAGS | SDMMC_INT_HLE) #define DW_MCI_SEND_STATUS 1 -- 1.7.12.4 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
