Subject: [PATCH 577/806] drm/v3d: Don't try to set OVRTMUOUT on V3D 4.x.
|
|
|
|
The old field is gone and the register now has a different field,
|
|
QRMAXCNT for how many TMU requests get serviced before thread switch.
|
|
We were accidentally reducing it from its default of 0x3 (4 requests)
|
|
to 0x0 (1).
|
|
|
|
v2: Skip setting the reg at all on 4.x, instead of trying to update
|
|
only the old field.
