[Why]
In USB4 DP tunneling, it's possible to have this scenario that
the path becomes unavailable and CM tears down the path a little bit late.
So, in this case, the HPD is high but fails to read any DPCD register.
That causes the link connection type to be set to sst.
And not all sinks are removed behind the MST branch.
[How]
Restore the link connection type if it fails to read DPCD register.

[WHY]
Hot plugging and then hot unplugging leads to k1 and k2 values to
change, as signal is detected as a virtual signal on hot unplug. Writing
these values to OTG_PIXEL_RATE_DIV register might cause primary display
to blank (known hw bug).
[HOW]
No longer write k1 and k2 values to register if signal is virtual, we
have safe guards in place in the case that k1 and k2 is unassigned so
that an unknown value is not written to the register either.

The VCN firmware loading path enables the indirect SRAM mode if it's
advertised as supported. We might have some cases of FW issues that
prevents this mode to working properly though, ending-up in a failed
probe. An example below, observed in the Steam Deck:
[...]
[drm] failed to load ucode VCN0_RAM(0x3A)
[drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0000)
amdgpu 0000:04:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vcn_dec_0 test failed (-110)
[drm:amdgpu_device_init.cold [amdgpu]] *ERROR* hw_init of IP block <vcn_v3_0> failed -110
amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_init failed
amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init
[...]
Disabling the VCN block circumvents this, but it's a very invasive
workaround that turns off the entire feature. So, let's add a quirk
on VCN loading that checks for known problematic BIOSes on Vangogh,
so we can proactively disable the indirect SRAM mode and allow the
HW proper probe and VCN IP block to work fine.

When FB_DAMAGE_CLIPS are provided in a non-MPO scenario, the loop does
not use the counter i. This causes the fill_dc_dity_rect() to always
fill dirty_rects[0], causing graphical artifacts when a damage clip
aware DRM client sends more than 1 damage clip.
Instead, use the flip_addrs->dirty_rect_count which is incremented by
fill_dc_dirty_rect() on a successful fill.

[Why]
On resume some displays are not ready for HDCP, so they will fail if we
start the hdcp authentintication too soon.
Add a delay so that the displays can be ready before we start.
NOTE: Previoulsy this delay was set to 3 seconds but it was causing
issues with compliance, 2 seconds should enough for compliance and the
s3 resume case.
[How]
Change the Delay to 2 seconds.

Always setup overdrive tables after resume. Preserve only some
user-defined settings in user_overdrive_table if they're set.
Copy restored user_overdrive_table into od_table to get correct
values.
On cold boot, BTC was triggered and GfxVfCurve was calibrated. We
got VfCurve settings (a). On resuming back, BTC will be triggered
again and GfxVfCurve will be recalibrated. VfCurve settings (b)
got may be different from those of cold boot. So if we reuse
those VfCurve settings (a) got on cold boot on suspend, we can
run into discrepencies.

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.

If the boot loader inode has never been used before, the
EXT4_IOC_SWAP_BOOT inode will initialize it, including setting the
i_size to 0. However, if the "never before used" boot loader has a
non-zero i_size, then i_disksize will be non-zero, and the
inconsistency between i_size and i_disksize can trigger a kernel

Reproducer:
1. create corrupted image and mount it:
mke2fs -t ext4 /tmp/foo.img 200
debugfs -wR "sif <5> size 25700" /tmp/foo.img
mount -t ext4 /tmp/foo.img /mnt

2. Run the reproducer program:
posix_memalign(&buf, 1024, 1024)
fd = open("file", O_RDWR | O_DIRECT);
ioctl(fd, EXT4_IOC_SWAP_BOOT);
write(fd, buf, 1024);
Fix this by setting i_disksize as well as i_size to zero when
initiaizing the boot loader inode.

Now, 'es->s_state' maybe covered by recover journal. And journal errno
maybe not recorded in journal sb as IO error. ext4_update_super() only
update error information when 'sbi->s_add_error_count' large than zero.
Then 'EXT4_ERROR_FS' flag maybe lost.
To solve above issue just recover 'es->s_state' error flag after journal
replay like error info.

The generic bmap() function exported by the VFS takes locks and does
checks that are not necessary for the journal inode. So allow the
file system to set a journal-optimized bmap function in
journal->j_bmap.

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().

if the file type has pollable uring_cmd support.
