Hello! I have a question about the transfer of CM23 (SET_BLOCK_COUNT), before starting a multiple block write CMD25. I want to set some of this CMD23 bits: BIT(31) stands for Reliable Write Request BIT(24) stands for Forced Programming I could only see usage of the Reliable Write Request for some rpmb ioctl: https://github.com/torvalds/linux/blob/master/include/uapi/linux/mmc/ioctl.h#L13 https://github.com/torvalds/linux/blob/master/drivers/mmc/core/block.c#L550 sbc.arg = data.blocks | (idata->ic.write_flag & BIT(31)); But there are also BITS MMC_DATA_REL_WR, MMC_DATA_FORCED_PRG https://github.com/torvalds/linux/blob/master/include/linux/mmc/core.h#L128 Used here: https://github.com/torvalds/linux/blob/master/drivers/mmc/core/block.c#L1301 Which confuses me. I am using the mmc_test code as example to execute a mmc block write. https://github.com/torvalds/linux/blob/master/drivers/mmc/core/mmc_test.c#L190 So i set the BIT(24): mrq->sbc->arg = blocks | BIT(24); But then i realized that the sdhci mmc host uses SDHCI_AUTO_CMD23 and mmc_test_prepare_sbc simply returns doing nothing. What would be the correct way to set the BIT(24) with CMD23 in the mmc_test example with a host which does SDHCI_AUTO_CMD23?
