The value is a bitfield using the bit positions defined in -include/linux/mmc/card.h. If the module parameter is placed in the -kernel command line (or bootargs) stored on the card then, assuming the -device only has one SD card interface, the override effectively becomes -card-specific. - -Signed-off-by: Phil Elwell <phil@raspberrypi.org> ---- - drivers/mmc/card/block.c | 28 +++++++++++++++++++++++++--- - 1 file changed, 25 insertions(+), 3 deletions(-) - ---- a/drivers/mmc/card/block.c -+++ b/drivers/mmc/card/block.c -@@ -137,6 +137,13 @@ enum { - module_param(perdev_minors, int, 0444); - MODULE_PARM_DESC(perdev_minors, "Minors numbers to allocate per device"); - -+/* -+ * Allow quirks to be overridden for the current card -+ */ -+static char *card_quirks; -+module_param(card_quirks, charp, 0644); -+MODULE_PARM_DESC(card_quirks, "Force the use of the indicated quirks (a bitfield)"); -+ - static inline int mmc_blk_part_switch(struct mmc_card *card, - struct mmc_blk_data *md); - static int get_card_status(struct mmc_card *card, u32 *status, int retries); -@@ -2571,6 +2578,7 @@ static int mmc_blk_probe(struct mmc_card - { - struct mmc_blk_data *md, *part_md; - char cap_str[10]; -+ char quirk_str[24]; - - /* - * Check that the card supports the command class(es) we need. -@@ -2578,7 +2586,16 @@ static int mmc_blk_probe(struct mmc_card - if (!(card->csd.cmdclass & CCC_BLOCK_READ)) - return -ENODEV; - -- mmc_fixup_device(card, blk_fixups); -+ if (card_quirks) { -+ unsigned long quirks; -+ if (kstrtoul(card_quirks, 0, &quirks) == 0) -+ card->quirks = (unsigned int)quirks; -+ else -+ pr_err("mmc_block: Invalid card_quirks parameter '%s'\n", -+ card_quirks); -+ } -+ else -+ mmc_fixup_device(card, blk_fixups); - - md = mmc_blk_alloc(card); - if (IS_ERR(md)) -@@ -2586,9 +2603,14 @@ static int mmc_blk_probe(struct mmc_card - - string_get_size((u64)get_capacity(md->disk), 512, STRING_UNITS_2, - cap_str, sizeof(cap_str)); -- pr_info("%s: %s %s %s %s\n", -+ if (card->quirks) -+ snprintf(quirk_str, sizeof(quirk_str), -+ " (quirks 0x%08x)", card->quirks); -+ else -+ quirk_str[0] = '\0'; -+ pr_info("%s: %s %s %s%s%s\n", - md->disk->disk_name, mmc_card_id(card), mmc_card_name(card), -- cap_str, md->read_only ?
