Hi Park,
Thanks a lot for the response.
It seems similar with TRIM. So how about to consider TRIM
implementation or extend it?
Yes, file system set REQ_DISCARD flag to notify block device driver to execute
TRIM.
And I noticed there's already a flag REQ_META used for file system meta data.
But
STM platforms use the sdhci-pltfm.c driver but, IMO
there are some problems when use the eMMC card.
--- from sdhci.c file:
1897if ((host-quirks SDHCI_QUIRK_BROKEN_CARD_DETECTION)
1898 mmc_card_is_removable(mmc))
1899 mmc-caps |= MMC_CAP_NEEDS_POLL;

Yes, I have been working on some changes that allow us to tag bios and
pass the information out to storage. These patches have been on the back
burner for a while due to other commitments. But I'll dig them out and
post them later. We just discussed them a couple of weeks ago at the

If there is only 1 function registered it is possible to
improve performance by directly calling the irq handler
and avoiding the overhead of reading the CCCR registers.

Interesting coincidence that the value of MMC_TYPE_SD and MMC_TYPE_SDIO
and MMC_TYPE_SD_COMBO have the relationship that SD_COMBO is the bitwise
OR of the other two. However, this seems to be more of a coincidence
than intentional. The #defines were clearly meant to be numeric values
rather
