That shouldn't matter? host->lock will make sure the requests are
serialized will it not?

Note: This is being send out for comment. We are still in the process of
testing this change
but we would like to have community review at this time.
SD 3.0 introduced additional drive strengths for UHS.
The card and the host can indicate 4 drive strengths as a bit
mask. Without local design
CMD19 -- The offical way to validate bus widths from the
JEDEC spec does not work on all platforms. Some platforms
that use PCI/PCIe to connect their SD controllers are known
to fail.
If the quirk MMC_BUS_WIDTH_TEST is not defined we try
to figure out the bus width by reading the ext_csd at diffe
Only compile tmio_mmc_dma.o when CONFIG_MMC_SDHI is selected (as y or m).

Just found Andrei Warkentin also submitted a RFC patch, which included more fix
for mounted root file system media. Please ignore this thread.

Hi all,
I encountered a dead lock issue. Two threads try to claim host, unfortunately
one thread needs to sync with the other. I encountered this issue with SD
card when testing system entering S3. Does anybody encounter the same issue?
Environment:
1. without CONFIG_MMC_UNSAFE_RESUME ope
10 matches
