Btw, the original purpose for the asic type check is to prevent any further
atombios call for RAS capability check. But it's not necessary to be there. We
shall consider to change it in a more reasonable approach by dropping the asic
type check.

Then we can refine the wording, or make this to be debug message, although the
message already states explicitly this is "optional". Split
amdgpu_ras_checked_support may not be a good idea since this is strictly not
correct - RAS is not necessarily bind to ASIC type.

Hi Hawking,
Yes, these kernel messages are indeed not harmful, but some audiences may feel
confused on this, as they will guess why kernel said " ras ta ucode is not
available " during boot up, and furthermore, if the users miss some FWs? So
this is to exclude the confusion
[AMD Public Use]
We shall check ras ta firmware image size or/and ras ta binary start address to
exclude ASICs that don't support ras.
Introduce asic type check here is unnecessary and the functional also need to
be modified every time we add a new asic with ras capablility.
Kernel message
From: Xiaogang Chen
amdgpu DM handles INTERRUPT_LOW_IRQ_CONTEXT interrupt(hpd, hpd_rx) by
using work queue and uses single work_struct. If previous interrupt
has not been handled new interrupts(same type) will be discarded and
driver just sends "amdgpu_dm_irq_schedule_work FAILED" message out.
From: Xiaogang Chen
drm_dp_check_and_send_link_address discovers MST device topology.
It can return both positive and negative values. When it returns positive
values there is no error found. If it returns negative values there is error
found, such as get NAK , timeout, etc. Following
Otherwise, below confused message is always printed during boot
for asics without ras feature, but with common ta firmware.

Mhm, I'm wondering if we shouldn't change the init sequence then. The

Driver cannot change amdgpu framebuffer (afb) format while doing
page flip. Force system doing so will cause ioctl error, and result in
breaking several functionalities including FreeSync.
If afb format is forced to change during page flip, following
Hi
You're probably best reporting the bug here:
https://gitlab.freedesktop.org/drm/amd/-/issues
Attach the output of dmesg from both Radeon and AMDGPU and the compositor /
Wayland logs (as you're not using X)
Cheers
