Subject: [PATCH] consolemap: Fix a memory leaking bug in
|
||||
drivers/tty/vt/consolemap.c
|
||||
|
||||
In function con_insert_unipair(), when allocation for p2 and p1[n]
|
||||
fails, ENOMEM is returned, but previously allocated p1 is not freed,
|
||||
remains as leaking memory. Thus we should free p1 as well when this
|
||||
allocation fails.

Subject: [PATCH] drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend
|
||||
|
||||
commit 87c1694533c947bf950251df3da04a32a05ede64 upstream
|
||||
|
||||
When audio power domain is suspended, the display driver must
|
||||
save state of AUD_FREQ_CNTRL on Tiger Lake and Ice Lake
|
||||
systems. The initial value of the register is set by BIOS and
|
||||
is read by driver during the audio component init sequence.

Subject: [PATCH] drm/i915: Fix audio power up sequence for gen10+ display
|
||||
|
||||
commit 1580d3cdddbba4a5ef78a04a5289e32844e6af24 upstream
|
||||
|
||||
On platfroms with gen10+ display, driver must set the enable bit of
|
||||
AUDIO_PIN_BUF_CTL register before transactions with the HDA controller
|
||||
can proceed. Add setting this bit to the audio power up sequence.
|
||||
|
||||
Failing to do this resulted in errors during display audio codec probe,
|
||||
and failures during resume from suspend.
|
||||
|
||||
Note: We may also need to disable the bit afterwards, but there are
|
||||
still unresolved issues with that.

Subject: [PATCH] Increase the ext4 default commit age
|
||||
|
||||
Both the VM and EXT4 have a "commit to disk after X seconds" time.
|
||||
Currently the EXT4 time is shorter than our VM time, which is a bit
|
||||
suboptional,
|
||||
it's better for performance to let the VM do the writeouts in bulk
|
||||
rather than something deep in the journalling layer.
|
||||

||||

Increase target_residency in cpuidle cstate

Tune intel_idle to be a bit less agressive;
|

Clear linux is cleaner in hygiene (wakupes) than the average linux,

so we can afford changing these in a way that increases
|

performance while keeping power efficiency

Subject: [PATCH] raid6: add Kconfig option to skip raid6 benchmarking
|
||||
|
||||
Adds CONFIG_RAID6_FORCE_ALGO, which causes the kernel to not benchmark
|
||||
each raid recovery and syndrome generation algorithm, and instead use
|
||||
the version selected via Kconfig (CONFIG_RAID6_FORCE_{INT,SSSE3,AVX2}).
|
||||
In the case, the selected algorithm is not supported by the processor at
|
||||
runtime, a fallback is used.

Subject: [PATCH] xattr: allow setting user.* attributes on symlinks by owner
|
||||
|
||||
Kvmtool and clear containers supports using user attributes to label host
|
||||
files with the virtual uid/guid of the file in the container. This allows an
|
||||
end user to manage their files and a complete uid space without all the ugly
|
||||
namespace stuff.
|
||||
|
||||
The one gap in the support is symlinks because an end user can change the
|
||||
ownership of a symbolic link. We support attributes on these files as you
|
||||
can already (as root) set security attributes on them.
|
||||
|
||||
The current rules seem slightly over-paranoid and as we have a use case this
|
||||
patch enables updating the attributes on a symbolic link IFF you are the
|
||||
owner of the synlink (as permissions are not usually meaningful on the link
|
||||
itself).

Change libahci to ignore firmware's staggered spin-up flag. End-users

who wish to honor firmware's SSS flag can add the following kernel
|

parameter to a new file at /etc/kernel/cmdline.d/ignore_sss.conf:
|
||||
libahci.ignore_sss=0
|

|
