           Summary: [nouveau] drmModeSetCursor->nouveau_bo_rd32->ioread32
                    provides high cpu load when using weston
                    drm-compositor
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)

Weston runned in drm-mode provide very high cpu load on mouse moving. I don`t
think that the bug of weston, seems problem in nouveau drm. At launch weston
have a log:

...
[24465.734894] nouveau W[   PFIFO][0000:02:00.0] INTR 0x00000001: 0x00000004

...


ioread32_native(ioread32 on litle-endian) using 100% of cpu core. If in weston
comment out drmModeSetCursor - cpu load is normal, but no see cursor ofcourse.
They copying cursor(64x64) from bo-object. Seems TTM iomem access provide very
high cpu load... On radeon it works smoothly and no have very high cpu load.


Kernel 3.9-rc5 (x86_64)
Wayland/Weston: git
Mesa: git
libdrm: git

--- Comment #1 from Pierre Moreau <pierre.morrow@free.fr> ---
Moving to Nouveau.

Are you still experiencing this issue with an updated graphic stack, aka.
kernel 3.18, mesa 10.4, libdrm 2.4.58 and waylaid/weston 1.6?
(The bug went unnoticed as it wasn't linked to Nouveau.)
