Just trying to make it easier to read. WREG32_FIELD(foo, FIELD, 1); Is easier to read than WREG32_P(foo, FOO__FIELD_MASK, ~FOO__FIELD_MASK); (also I already pushed them after getting a RB by Christian this morning so we might need to hold a different discussion). I agree it's not really a functional change but making things a bit more uniform and easier to read helps maintenance. And I did find a bug in the process :-) Tom ________________________________ From: Deucher, Alexander Sent: Thursday, August 11, 2016 11:46 To: 'Tom St Denis'; amd-gfx at lists.freedesktop.org Cc: StDenis, Tom Subject: RE: [PATCH 3/4] drm/amd/amdgpu: VCE v2 register cleanup > -----Original Message----- > From: amd-gfx [mailto:amd-gfx-bounces at lists.freedesktop.org] On Behalf > Of Tom St Denis > Sent: Thursday, August 11, 2016 10:33 AM > To: amd-gfx at lists.freedesktop.org > Cc: StDenis, Tom > Subject: [PATCH 3/4] drm/amd/amdgpu: VCE v2 register cleanup > > Signed-off-by: Tom St Denis <tom.stdenis at amd.com> A couple pieces of this patch could be split out as separate cleanups (see below). However, I'm not sure how much value there is in switching WREG32_P for WREG_FIELD other than code churn. They basically do the same thing.
