[Intel-gfx] [PATCH v6 0/2] drm/i915/display/dsc: Set BPP in the kernel

[Intel-gfx] [PATCH v6 0/2] drm/i915/display/dsc: Set BPP in the kernel

[venkata.sai.patnana]

From: Patnana Venkata Sai <venkata.sai.patnana@intel.com>

DSC can be supported per DP connector. This patch creates
a per connector debugfs node to expose the Input and
Compressed BPP.

The same node can be used from userspace to force
DSC to a certain BPP.

force_dsc_bpp is written through this debugfs
node to force DSC BPP to all accepted values

[venkata.sai.patnana]

From: Patnana Venkata Sai <venkata.sai.patnana@intel.com>

[What]:
This patch creates a per connector debugfs node to expose
the Input and Compressed BPP.

The same node can be used from userspace to force
DSC to a certain BPP(all accepted values).

[Why]:
Useful to verify all supported/requested compression bpp's
through IGT

v2: Remove unnecessary logic (Jani)
v3: Drop pipe bpp in debugfs node (Vandita)
v4: Minor cleanups (Vandita)
v5: Fix NULL pointer dereference
v6: Fix dim tool checkpatch errors
    Release the lock before return (Vandita)

This is difficult to review because there is so much that should be
fixed in intel_display_debugfs.c in general and in this patch
specifically.

I think the first thing here is... have you actually tried this and
verified it works?

Just by reading the code, I don't think it is usable.

General: I don't understand why we keep passing drm_connector instead of
intel_connector as private data.

Unnecessary initialization.

In general we use

	ret = -ENODEV;
        goto out;

with the unlock and other cleanup at the end, same unlock for both
success and fail paths. It's the prevalent style in kernel. Same all
over.

Usually the more "context" style variables go first.

Should be unnecessary.

Ditto here about failure path.

This is odd. In order to have crtc_state->pipe_bpp, or crtc state, you
must have done a modeset. That modeset must have been done without the
force_dsc_bpp. So in order to use this code, the test needs to:

- do a modeset
- set the force bpp
- do another modeset for the change to take effect

I don't think it makes sense to make that a requirement. Maybe we
shouldn't even require connector_status_connected. Just find intel_dp
and set ->force_dsc_bpp. Next modeset will use it. Have the value check
there.

This code also prevents you from resetting the force_dsc_bpp. If you set
it once, you can't set it back to 0 afterwards.

This is a completely useless debug message.

Maybe this should use DEFINE_SEQ_ATTRIBUTE() to avoid some boilerplate.

I don't understand how either i915_dsc_fec_support or
i915_dsc_bpp_support (which is an odd name for something to set an
integer value to!) can work if their mode is read-only 0444.

Has either been tested?

AFAICT you could just move the if (intel_dp->force_dsc_bpp) here, and
overwrite pipe_config->dsc.compressed_bpp. The branches above are
already too complicated and in need of refactoring, no need to duplicate
the same code in two places there IMO.

Unnecessary change. You already log the force DSC BPP once.
