Subject: [PATCH] dri: Fix BGR format exclusion
|
|
|
|
The check we had for BGR vs. RGB formats was testing completely the
|
|
wrong thing. Fix it so we can restore the previous set of configs we
|
|
expose to the frontend, which also fixes surfaceless platform on s390x.
|
|

Fixes: ad0edea53a73 ("st/dri: Check format properties from format helpers")
|
|
Closes: mesa/mesa#11360
