Hello.  Kernel 6.11.0 crashes.  6.10.0 builds.  Al Viro and Dr. David 
Alan Gilbert have been helpful, and asked that I

post a git bisect log.  The last log step seems odd, but the second last 
step "Remove useless function call" might be what broke.

My hardware is old corei7 quad core/8 thread Tylersberg/Nehalem with an 
AMD RX 6500XT.  That's the odd combination.

Thanks in advance,

Bob

Thank you for doing this!

My reading is that's fine, I think the next one:

tree: git bisect bad
[a171cce57792b0a6206d532050179a381ad74f8f] drm/amd/display: Check and log for

or the one after it is the culprit?

Adding the two Alex's from AMD back onto the thread.

The commit triggers debugger in case of in case of errors.

Is the config CONFIG_DEBUG_KERNEL_DC (Enable kgdb break in DC) enabled 
in .config, i.e. can you check "grep CONFIG_DEBUG_KERNEL_DC .config"?

If so, can you also try to disable it and check whether you can see 
error messages "Failed to execute VBIOS command table" in kernel log?

Hi.  Sorry for the late reply.  My config has
CONFIG_DEBUG_KERNEL_DC=y

I will set it to # CONFIG_DEBUG_KERNEL_DC is not set

also,

cat /var/log/kern.log | grep VBIOS       gives

Hopefully this helps.  Please mail me if you for more information.  I 
have changed my .config and set

# CONFIG_DEBUG_KERNEL_DC is not set

I am attempting to build 6.11.0.

Thanks,

Hi Bob,

It seems the below change in a171cce57792 causes the hang when 
CONFIG_DEBUG_KERNEL_DC is set.

--- a/drivers/gpu/drm/amd/display/dc/bios/command_table2.c

If you can help confirm thefollowing fix the hang, I will prepare a 
revert patch next week:

* Set CONFIG_DEBUG_KERNEL_DC and revert the above change, i.e.

  Cc: linux-kernel, regressions

So the final change:

CONFIG_DEBUG_KERNEL_DC=y

(about line 227) of drivers/gpu/drm/amd/display/dc/bios/command_table2.c

BIOS_CMD_TABLE_REVISION(dig1transmittercontrol, frev, crev);

with the 6.11.0 kernel,

and the X server is working OK.

Thanks,

Bob

There is a fix in amd-staging-drm-next:

3e54e61e5636 drm/amd/display: only trigger BIOS related assert for older 
ASICs

--- a/drivers/gpu/drm/amd/display/dc/bios/command_table2.c
+++ b/drivers/gpu/drm/amd/display/dc/bios/command_table2.c
@@ -227,7 +227,7 @@ static void init_transmitter_control(struct 
bios_parser *bp)
         uint8_t frev;
         uint8_t crev = 0;

-       if (!BIOS_CMD_TABLE_REVISION(dig1transmittercontrol, frev, crev))
+       if (!BIOS_CMD_TABLE_REVISION(dig1transmittercontrol, frev, crev) 
&& (bp->base.ctx->dc->ctx->dce_version <= DCN_VERSION_2_0))


It should land in 6.12. See
