As per discussion [1], it seems like it should be quite safe to turn
on PROBE_PREFER_ASYNCHRONOUS for all sd/mmc host controllers. Let's
give it a shot. For some discussion about this flag, see the commit
message for commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous
probe").
I've broken this series into chunks based on LTS kernel releases to
attempt to make it easier if someone wanted to cherry-pick it to an
older kernel. While these cherry-picks won't be conflict free, there
should only be trivial context conflicts and no problems with drivers
that are totally missing. This is a bit of a compromise between a
1-big patch and a many-part patch series.
I have only tested this on a rk3399-kevin (sdhci-of-arasan) and a
rk3288-veyron (dw_mmc-rockchip) device and only lightly. If this
patch causes anyone problems those drivers should be marked with
PROBE_FORCE_SYNCHRONOUS, debugged, and then go back to prefer
asynchronous. Any problems are likely just a hidden bug that has been
exposed by this change.
NOTE: in theory, it'd be nice if there was a KConfig option that we
could flip that would turn on async probe everywhere (except for those
that opt out by adding PROBE_FORCE_SYNCHRONOUS). My hope is that by
adding this flag in more places it will become clear that this flag is
working reliably and easier to move over when we're ready.
While coccinelle is too difficult for my feeble brain, I managed to
whip up a pretty terrible python script to help with this. For your
edification:
import os
import sys
import re
for filename in os.listdir("."):
found_plat = False
found_driver = False
output = []
for line in open(filename, "r").readlines():
output.append(line)
if "struct platform_driver" in line:
found_plat = True
if found_plat and re.search(r"\t\.driver\s*=\s*{", line):
found_driver = True
found_plat = False
mo = re.search(r"(\s*)\.name(\s*)=", line)
if found_driver and mo:
if mo.group(2) == " ":
space = " "
elif mo.group(2) == "\t":
# Best we can do
space = " "
elif mo.group(2).startswith("\t"):
# Guess that removing one tab is right
space = mo.group(2)[1:]
else:
# Guess it's all spaces
space = mo.group(2)[7:] + " "
output.append("%s.probe_type%s= PROBE_PREFER_ASYNCHRONOUS,\n" % (mo.group(1), space))
found_driver = False
open(filename, "w").write("".join(output))

The LTS granularity of patches is a nice idea! I will keep it in mind.

SD/MMC, I think.

For these two also:

The speedups somewhat match the expected values and no regressions when
checksumming a large file.

can this somehow change the order in which the MMC drivers end up loading?
on Amlogic SoCs we have up to three MMC controllers, some SoCs even
use two different MMC controller IPs (and therefore two different
drivers).
so far the MMC controller naming (/dev/mmcblk* etc.) was consistent -
can that change with this patch?
apologies if this has been discussed and answered anywhere
Best regards,
Martin

Right now, only the dw_mmc driver family supports aliases for mmc nodes.

Consistency has never been guaranteed. Just imagine one of the mmc
host drivers ending up lacking some of its resources during ->probe()
and returning -EPROBE_DEFER.
UUID/PARTID has been the only way.

Yes, this is now possible due to the recently [1] applied patches for
supporting mmc aliases.

That's "mshc" specific (related to the old multiple slot support I
think), but not affecting the mmc aliases, which the mmc core now is
supporting.
So the mmc aliases are common for all mmc hosts. Please have a look at
the new OF parsing in mmc_alloc_host().

An interesting idea about a patch per LTS release. I think it makes
perfect sense in this type of case.
Let's give this a shot in next and see how it goes. So, applied for
next, thanks!
