Subject: [Intel-gfx] [PATCH v4] drm/i915/tgl: Add Wa_1606054188:tgl
Date: Mon, 24 Feb 2020 14:36:51 -0800 [thread overview]
Message-ID: <20200224223651.3801646-1-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20200201082834.10163-1-matthew.s.atwood@intel.com>
From: Matt Atwood <matthew.s.atwood@intel.com>
On Tiger Lake we do not support source keying in the pixel formats P010,
P012, P016.
v2: Move WA to end of function. Create helper function for format
check. Less verbose debugging messaging.
v3: whitespace
v4(MattR):
- Actually return EINVAL to reject this combination.
- Pass format parameter as u32.
- Make test TGL-specific for now.
- Switch to per-device logging.
- Shorten/simplify comment.
Bspec: 52890
