Hi, I can relatively easily reproduce this bug: BUG: 'list_empty(&vgdev->free_vbufs)' is true! ------------[ cut here ]------------ kernel BUG at /home/latest/linux/drivers/gpu/drm/virtio/virtgpu_vq.c:130! invalid opcode: 0000 [#1] PREEMPT SMP KASAN Modules linked in: CPU: 1 PID: 355 Comm: kworker/1:2 Not tainted 4.9.0-rc2-next-20161028+ #32 Hardware name: QEMU Standard PC (i440FX

This is the latest version of https://patchwork.freedesktop.org/series/46815/ With a bunch of fixes to the new fb_helper to prevent it from breaking module loading/unloading with nouveau. Also; lots of documentation fixes and one fix in response to a kbuild bot. Lyude Paul (8): drm/nouveau: Fix bogus drm_kms_helper_poll_enable() placement drm/nouveau: Enable polling even if we have runtime

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3 are enough to make the atmel-hlcdc driver do what I need (when patched

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. Boris and Daniel, was this approximately what you had in mind? I have obviously not tested all of this with more than a compile, but the first patch is
