Quoting Tvrtko Ursulin (2018-12-03 12:50:08) > From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> > > To enable later verification of GT workaround state at various stages of > driver lifetime, we record the list of applicable ones per platforms to a > list, from which they are also applied. > > The added data structure is a simple array of register, mask and value > items, which is allocated on demand as workarounds are added to the list. > > This is a temporary implementation which later in the series gets fused > with the existing per context workaround list handling. It is separated at > this stage since the following patch fixes a bug which needs to be as easy > to backport as possible. > > Also, since in the following patch we will be adding a new class of > workarounds (per engine) which can be applied from interrupt context, we > straight away make the provision for safe read-modify-write cycle. > > v2: > * Change dev_priv to i915 along the init path. (Chris Wilson) > * API rename. (Chris Wilson) > > v3: > * Remove explicit list size tracking in favour of growing the allocation > in power of two chunks. (Chris Wilson) > > v4: > Chris Wilson: > * Change wa_list_finish to early return. > * Copy workarounds using the compiler for static checking. > * Do not bother zeroing unused entries. > * Re-order struct i915_wa_list. > > Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> > Reviewed-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> # v2 Reviewed-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
