See the commits 05a8c4904699..16da528365de in https://abf.io/kernels_stable/kernel-4.6. Hightlights: * New build model: everything in a single project. * PAE by default on i586. No non-PAE flavours remain. * SELinux is now built in (disabled by default). * Dropped ndiswrapper (can be built separately if it is really needed).

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().
|
|
