Are you sure this is an eMMC problem and not a mmc host driver issue?
Can you elaborate more what happens?
Kind regards

Hi

>Can you elaborate more what happens?
When I use the mkfs.f2fs tool to format the eMMC file system on the imx8qxp board,
because mkfs.f2fs will use secdiscard first, when entering mmc_blk_issue_secdiscard_rq erase,
once the parameters are passed into MMC_SECURE_TRIM1_ARG, this function will take a long time to return .
The program has not ended, has been in TASK_UNINTERRUPTIBLE state.
I compared the mkfs.ext4 tool to format the file system. Because it directly uses mmc_blk_issue_discard_rq,
this is a normal formatting phenomenon.
mmc_blk_issue_secdiscard_rq and mmc_blk_issue_discard_rq are just different commands and parameters sent by the host as a bus.
I did not see the description of trim in the data sheet. Could the host driver cause this problem?
Note:
The host driver I use is sdhci-esdhc-imx.c
Thanks

Yes, it can - and we have had issues like these before. So before
adding a card quirk, I think we need to make sure this isn't the case.
When using MMC_SECURE_TRIM1_ARG, it's very likely that the request
takes longer to complete.
The mmc host is responsible for either dealing with busy detection
with the help of its HW/controller - or if that can't be supported,
the mmc core falls back to polling the card for busy with a CMD13.
See mmc_do_erase() in /drivers/mmc/core/core.c

Hi Ulf and Xiaolei,
I use the mkfs.f2fs tool format a partition on one Sandisk eMMC chip on imx8 platform, do not meet issue.
I add some log, confirm mkfs.f2fs call the mmc_blk_issue_secdiscard_rq(), and the arg is MMC_SECURE_TRIM1_ARG.
For the busy detection, imx usdhc has one register bit represent the dat0 signal level. So for your mmc device, it should be the mmc device trim feature problem.
