Hi Larry Wei, hi Ben,

For context this is about https://bugs.debian.org/1103397, and which
Ben did forward in
https://lore.kernel.org/regressions/dddb6b8d56e3f28b914e1e243f948457d53149ce.camel@decadent.org.uk/T/

Going thorough the bugs I notice there was a related upstream
discussion/patch relating to ae6012d72fa6 ("x86/pkeys: Ensure updated
PKRU value is XRSTOR'd")  in the following:

https://lore.kernel.org/all/20250102075419.2559-1-TonyWWang-oc@zhaoxin.com/

There were some followups, but discussion ended on 18.01.2025.

Did this felt through the cracks?

Regards,
Salvatore

Salvatore Bonaccorso,

Yes, let's just consider it as good. But in fact, there are still many 
problems, such as the one mentioned above 
(https://linux-hardware.org/?probe=271fabb7a4&log=dmesg), and almost all 
laptops using Zhaoxin CPUs cannot adjust the backlight brightness, which 
is **VERY HARMFUL** to the eyes!

Dear Larry,

We are currently investigating the causes of the WARNING messages you 
mentioned in this log:
[    4.141284] ------------[ cut here ]------------
[    4.141285] alg: self-tests for sha1 using sha1-padlock-nano failed 
(rc=-22)
[    4.141302] WARNING: CPU: 2 PID: 657 at crypto/testmgr.c:5865 
alg_test.cold+0xb7/0xe0

Regarding the inability to adjust the laptop backlight brightness, we 
believe this issue is unlikely related to the CPU itself. It is 
recommended to contact the laptop manufacturer to confirm whether the 
device supports backlight brightness adjustment and inquire about 
specific configuration methods, such as installing specific EC 
controller drivers or updating graphics card drivers.

BRs!

Dear TonyWWang-oc,

Yes, but actually, these graphics cards are your products, and neither 
C-960 nor C-1080 seem to be open source.The drivers provided on your 
official website do not seem to be used for Debian.I downloaded your 
drivers and extracted them, and I found that each file has the license 
content.Can I assume that these drivers are open source?

Regards,

larryw3i

Dear Larry,

The graphics driver package contains both kernel-mode and user-mode
components, where the kernel-mode components are open source, while
graphics rendering tasks predominantly rely on user-mode implementations.
