This reverts commit 58973046c1bf ("regulator: qcom-rpmh: Use
PROBE_FORCE_SYNCHRONOUS"). Further digging into the problems that
prompted the us to switch to synchronous probe showed that the root
cause was a missing "rootwait" in the kernel command line
arguments. Let's reinstate asynchronous probe.

Restore synchronous probing for Arizona regulators as the main MFD
relies on the ordering of the devices probing.
As these regulators are built into the CODEC and typically have no DT
representation the regulator framework is unaware of their existence
until the driver probes. These means the probing of the driver needs to
be synchronous to ensure the regulators are not substitued for the dummy
later when the users request them.

Merge series from Douglas Anderson <dianders@chromium.org>:
This series directly follows from the discussion when I tried to turn
on PROBE_PREFER_ASYNCHRONOUS just for the fixed-regulator [1] and
attempts to switch everything in drivers/regulator over to async
probe.
Like the similar patch series I did for the MMC subsystem a few years
ago [2], I've split this patch series into batches corresponding to
drivers corresponding to actively maintained stable kernel trees with
the idea to break the patch series up somewhat.
Most of the description of this series is contained in the first patch
of the series and then the further patches simply refer back to the
first one. The logic and reasoning behind all the patches is exactly
the same.
As talked about in the first patch, it wouldn't be at all shocking if
this broke someone. Hopefully this doesn't cause too much of a
problem. Most of the problems expected would be real underlying bugs
that already existed and were just tickled by this change. If you're
facing a problem, it's fairly easy to force individual drivers back to
"synchronous" probing while the problem is tracked down and fixed.
I am opting _not_ to CC every single person involved in each of these
regulators on this patch series because I suspect that the mailing
lists couldn't handle CCing that many people. This should be on LKML
so hopefully people can find it there and respond to it that
way. Anyone who responds will get CCed on future versions, if there
are any.
For reference, the ugly script I used is here:
import os
import re
for filename in os.listdir("."):
found_subsys = False
found_driver = False
output = []
for line in open(filename, "r").readlines():
if "struct platform_driver" in line or \
"struct i2c_driver" in line or \
"struct spmi_driver" in line or \
"struct spi_driver" in line:
found_subsys = True
if found_subsys and re.search(r"\t\.driver\s*=\s*{", line):
found_driver = True
found_subsys = False
mo = re.search(r"(\s*)\.name(\s*)=", line)
if found_driver and mo:
if not line.endswith(",\n"):
line = line[:-1] + ",\n"
output.append(line)
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
else:
output.append(line)
open(filename, "w").write("".join(output))
I manually split drivers up into groups based on the kernel they were
introduced in.
I've run a compile test against "allyesconfig" on amd64, arm32, and
arm64 with this and confirmed it compiled. I've booted this on a
sc7180-trogdor-lazor board and confirmed it booted OK and got the boot
speed improvements I expected and that dmesg was as expected.

Probing of regulators can be a slow operation and can contribute to
slower boot times. This is especially true if a regulator is turned on
at probe time (with regulator-boot-on or regulator-always-on) and the
regulator requires delays (off-on-time, ramp time, etc).
While the overall kernel is not ready to switch to async probe by
default, as per the discussion on the mailing lists [1] it is believed
that the regulator subsystem is in good shape and we can move
regulator drivers over wholesale. There is no way to just magically
opt in all regulators (regulators are just normal drivers like
platform_driver), so we set PROBE_PREFER_ASYNCHRONOUS for all
regulators found in 'drivers/regulator' individually.
Given the number of drivers touched and the impossibility to test this
ahead of time, it wouldn't be shocking at all if this caused a
regression for someone. If there is a regression caused by this patch,
it's likely to be one of the cases talked about in [1]. As a "quick
fix", drivers involved in the regression could be fixed by changing
them to PROBE_FORCE_SYNCHRONOUS. That being said, the correct fix
would be to directly fix the problem that caused the issue with async
probe.
The approach here follows a similar approach that was used for the mmc
subsystem several years ago [2]. In fact, I ran nearly the same python
script to auto-generate the changes. The only thing I changed was to
search for "i2c_driver", "spmi_driver", and "spi_driver" in addition
to "platform_driver".

booted
This is very close to a straight revert of commit 218320fec294
("regulator: core: Fix off-on-delay-us for always-on/boot-on
regulators"). We've identified that patch as causing a boot speed
regression on sc7180-trogdor boards. While boot speed certainly isn't
more important than making sure that power sequencing is correct,
looking closely at the original change it doesn't seem to have been
fully justified. It mentions "cycling issues" without describing
exactly what the issues were. That means it's possible that the
cycling issues were really a problem that should be fixed in a
different way.
Let's take a careful look at how we should handle regulators that have
an off-on-delay and that are boot-on or always-on. Linux currently
doesn't have any way to identify whether a GPIO regulator was already
on when the kernel booted. That means that when the kernel boots we
probe a regulator, see that it wants boot-on / always-on we, and then
turn the regulator on. We could be in one of two cases when we do
this:
a) The regulator might have been left on by the bootloader and we're
ensuring that it stays on.
b) The regulator might have been left off by the bootloader and we're
just now turning it on.
For case a) we definitely don't need any sort of delay. For case b) we
_might_ need some delay in case the bootloader turned the regulator
off _right_ before booting the kernel. To get the proper delay for
case b) then we can just assume a `last_off` of 0, which is what it
gets initialized to by default.
As per above, we can't tell whether we're in case a) or case b) so
we'll assume the longer delay (case b). This basically puts the code
to how it was before commit 218320fec294 ("regulator: core: Fix
off-on-delay-us for always-on/boot-on regulators"). However, we add
one important change: we make sure that the delay is actually honored
if `last_off` is 0. Though the original "cycling issues" cited were
vague, I'm hopeful that this important extra change will be enough to
fix the issues that the initial commit mentioned.
With this fix, I've confined that on a sc7180-trogdor board the delay
at boot goes down from 500 ms to ~250 ms. That's not as good as the 0
ms that we had prior to commit 218320fec294 ("regulator: core: Fix
off-on-delay-us for always-on/boot-on regulators"), but it's probably
safer because we don't know if the bootloader turned the regulator off
right before booting.
One note is that it's possible that we could be in a state that's not
a) or b) if there are other issues in the kernel. The only one I can
think of is related to pinctrl. If the pinctrl driver being used on a
board isn't careful about avoiding glitches when setting up a pin then
it's possible that setting up a pin could cause the regulator to "turn
off" briefly immediately before the regulator probes. If this is
indeed causing problems then the pinctrl driver should be fixed,
perhaps in a similar way to what was done in commit d21f4b7ffc22
("pinctrl: qcom: Avoid glitching lines when we first mux to output")

tpm: disable hwrng for fTPM on some AMD designs
tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address
|
|
AMD has issued an advisory indicating that having fTPM enabled in
BIOS can cause "stuttering" in the OS. This issue has been fixed
in newer versions of the fTPM firmware, but it's up to system
designers to decide whether to distribute it.
This issue has existed for a while, but is more prevalent starting
with kernel 6.1 because commit b006c439d58db ("hwrng: core - start
hwrng kthread also for untrusted sources") started to use the fTPM
for hwrng by default. However, all uses of /dev/hwrng result in
unacceptable stuttering.
So, simply disable registration of the defective hwrng when detecting
these faulty fTPM versions. As this is caused by faulty firmware, it
is plausible that such a problem could also be reproduced by other TPM
interactions, but this hasn't been shown by any user's testing or reports.
It is hypothesized to be triggered more frequently by the use of the RNG
because userspace software will fetch random numbers regularly.
Intentionally continue to register other TPM functionality so that users
that rely upon PCR measurements or any storage of data will still have
access to it. If it's found later that another TPM functionality is
exacerbating this problem a module parameter it can be turned off entirely
and a module parameter can be introduced to allow users who rely upon
fTPM functionality to turn it on even though this problem is present.

tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI
table is found. If the firmware vendor includes an invalid log address
we are unable to map from the ACPI memory and tpm_read_log() returns -EIO
which would abort discovery of the eventlog.
Change the return value from -EIO to -ENODEV when acpi_os_map_iomem()
fails to map the event log.

The cpumask_check() was unnecessarily tight, and causes problems for the
users of cpumask_next().
We have a number of users that take the previous return value of one of
the bit scanning functions and subtract one to keep it in "range". But
since the scanning functions end up returning up to 'small_cpumask_bits'
instead of the tighter 'nr_cpumask_bits', the range really needs to be
using that widened form.
[ This "previous-1" behavior is also the reason we have all those
comments about /* -1 is a legal arg here. */ and separate checks for
that being ok. So we could have just made "small_cpumask_bits-1"
be a similar special "don't check this" value.
Tetsuo Handa even suggested a patch that only does that for
cpumask_next(), since that seems to be the only actual case that
triggers, but that all makes it even _more_ magical and special. So
just relax the check ]
One example of this kind of pattern being the 'c_start()' function in
arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on
other architectures.

Above issue happens as follows:
ext4_iget
ext4_find_inline_data_nolock ->i_inline_off=164 i_inline_size=60
ext4_try_add_inline_entry
__ext4_mark_inode_dirty
ext4_expand_extra_isize_ea ->i_extra_isize=32 s_want_extra_isize=44
ext4_xattr_shift_entries
->after shift i_inline_off is incorrect, actually is change to 176
ext4_try_add_inline_entry
ext4_update_inline_dir
get_max_inline_xattr_value_size
if (EXT4_I(inode)->i_inline_off)
entry = (struct ext4_xattr_entry *)((void *)raw_inode +
EXT4_I(inode)->i_inline_off);
free += EXT4_XATTR_SIZE(le32_to_cpu(entry->e_value_size));
->As entry is incorrect, then 'free' may be negative
ext4_update_inline_data
value = kzalloc(len, GFP_NOFS);
-> len is unsigned int, maybe very large, then trigger warning when
'kzalloc()'
To resolve the above issue we need to update 'i_inline_off' after
'ext4_xattr_shift_entries()'. We do not need to set
EXT4_STATE_MAY_INLINE_DATA flag here, since ext4_mark_inode_dirty()
already sets this flag if needed. Setting EXT4_STATE_MAY_INLINE_DATA
when it is needed may trigger a BUG_ON in ext4_writepages().

The only caller of ext4_find_inline_data_nolock() that needs setting of
EXT4_STATE_MAY_INLINE_DATA flag is ext4_iget_extra_inode(). In
ext4_write_inline_data_end() we just need to update inode->i_inline_off.
Since we are going to add one more caller that does not need to set
EXT4_STATE_MAY_INLINE_DATA, just move setting of EXT4_STATE_MAY_INLINE_DATA
out to ext4_iget_extra_inode().

"kmap_local_page() conversions in local filesystems keep running into
kunmap_local_page()+put_page() combinations. We can keep inventing
names for identical inline helpers, but it's getting rather
inconvenient. I've added a trivial helper to linux/highmem.h instead.
I would've held that back until the merge window, if not for the mess
it causes in tree topology - I've several branches merging from that
one, and it's only going to get worse if e.g. ext2 stuff gets picked
by Jan"

Pull misc fixes from Al Viro:
"pick_file() speculation fix + fix for alpha mis(merge,cherry-pick)
The fs/file.c one is a genuine missing speculation barrier in
pick_file() (reachable e.g. via close(2)). The alpha one is strictly
speaking not a bug fix, but only because confusion between
preempt_enable() and preempt_disable() is harmless on architecture
without CONFIG_PREEMPT.
Looks like alpha.git picked the wrong version of patch - that braino
used to be there in early versions, but it had been fixed quite a
while ago..."
