Earlier, the patches were kept in the respective branches of a separate project, https://abf.io/soft/kernel-patches-and-configs. And before that - in the custom tarballs. Now all the patches are kept here along with the spec file and are applied the default way rather than by separate scripts. This should make the maintenance of the patches as well as the experiments with the new ones a lot easier. The previous scheme seemed to offer a bit more flexibility (different patch sets for different cases) at the cost of maintenance. But as it turned out, that flexibility was not worth it and was rarely used, at most.

Subject: [PATCH] drm/cirrus: Use 16bpp as default
|
|
Patch-mainline: Submitted
|
|
References: bnc#799216
|
|
|
|
We've got a bug report that GNOME on QEMU shows wrong colors.
|
|
It turned out that it's because Cairo doesn't support 24bpp well.
|
|
This hasn't been an issue until now because we (at least SUSE and
|
|
Fedora) have a patch to use 16bpp for QEMU in Xorg cirrus UMS driver.
|
|
|
|
Since cirrus KMS driver is mainly targeted for the use on QEMU/KVM, we
|
|
should choose 16bpp as default, too.
|
|
|
|
Also, it's not convenient to set the default bpp in multiple places.
|
|
cirrus_fbdev_init() should check the original preferred depth set in
|
|
cirrus_modeset_init().
|
|
