[PATCH v2 0/9] drm/amdgpu: Add jpeg devcoredump support

[Sathishkumar S]

This patch-series enables jpeg devcoredump support

V2: (Lijo)
 - add amdgpu_jpeg_reg_dump_init() for memory allocation and reg_list ref
 - use reg_list and reg_count from init() to dump and print registers
 - add amdgpu_jpeg_reg_dump_fini() to free memory and clear reg_list ref

Sathishkumar S (9):
  drm/amdgpu: Add a func for core specific reg offset
  drm/amdgpu: Add helper funcs for jpeg devcoredump
  drm/amdgpu: Enable devcoredump for JPEG4_0_3
  drm/amdgpu: Enable devcoredump for JPEG5_0_1
  drm/amdgpu: Enable devcoredump for JPEG4_0_0
  drm/amdgpu: Enable devcoredump for JPEG4_0_5
  drm/amdgpu: Enable devcoredump for JPEG3_0_0
  drm/amdgpu: Enable devcoredump for JPEG2_0_0
  drm/amdgpu: Enable devcoredump for JPEG2_5_0

[PATCH v2 1/9] drm/amdgpu: Add a func for core specific reg offset

[Sathishkumar S]

Add an inline function to calculate core specific register offsets for
JPEG v4.0.3 and reuse it, makes code more readable and easier to align.

[PATCH v2 2/9] drm/amdgpu: Add helper funcs for jpeg devcoredump

[Sathishkumar S]

Add devcoredump helper functions that can be reused for all jpeg versions.

V2: (Lijo)
 - add amdgpu_jpeg_reg_dump_init() and amdgpu_jpeg_reg_dump_fini()
 - use reg_list and reg_count from init() to dump and print registers
 - memory allocation and freeing is moved to the init() and fini()

Thanks, this is almost there. Personally, would still prefer something
like below and have an instance of this kept inside jpeg_inst (though I
see your point that jpeg_inst doesn't have an instance id and this will
also mean duplicating list pointer/num reg info in all instances).

amdgpu_jpeg_reg_dump {
	u32 *ip_dump;
	u32 reg_count;
	const struct amdgpu_hwip_reg_entry *reg_list;
};

Ignoring that -

With the current way,

amdgpu_jpeg_reg_dump_fini() may be called from within sw_fini(). Just
wanted to keep a wrapper fini() func to make sure all is cleaned up.
That would avoid calling this from every IP version.

Apart from those, leaving it to Leo or someone else from JPEG to take a
look.

LIjo

The multiple copies is one reason I am trying to avoid this approach, 
and we can still print only
the affected instance registers in devcoredump in the future if support 
for it comes up.

Thank you, would prefer to have single reference of the

Can we have it the current way instead ? as few ip_versions do not 
support devcoredump yet and calling
reg_dump_fini() for every ip version irrespective of the  support is 
redundant, if we add that in sw_fini().

Just add a check for reg_list being non-null and that should take care.
Then this doesn't need to be taken care when more IP versions are added.
Also kfree on NULL is harmless.

Any init() caller should be responsible for calling the corresponding 
fini() as well,
it is either good to have both amdgpu_jpeg_reg_dump_init()/fini() moved 
inside sw_init/sw_fini
or leave it to the helper function consumers to call both init() and 
fini() themselves.

Re: [PATCH v2 9/9] drm/amdgpu: Enable devcoredump for JPEG2_5_0

[Leo Liu]

Looks pretty good to me. One question that why this is not added to JPEG 
5_0_0? Since the patch 3-9 cover the rest of versions, they are:

Re: [PATCH v2 9/9] drm/amdgpu: Enable devcoredump for JPEG2_5_0

[Sundararaju, Sathishkumar]

Hi Leo,

Oh! I somehow missed it, I will enable it in 5_0_0 as well.
Initially I had some confusion around 4_0_5 and 5_0_0 as they both are 
in dpg mode, but after checking the existing register access I enabled 
it in 4_0_5, but missed to enable it in 5_0_0.

Regards,
Sathish
