Hi all,
I backported nouveau-git20100222 to pv_ops 2.6.31.6 by replacing the whole
drm-tree and includes. Just needed a minor fix in drm_sysfs.c to compile.
nouveau works fine with 2D acceleration enabled when booted without xen.
Even nouveau-dri works!
But when booted on Xen, X hangs if Accel enabled
Works fine with Option NoAccel True in xorg.conf.
Found to be stuck in nv_accel_common_init.
Call traced in xf86-nouveau:
in nv_accel_common.c;
NVAccelInit2D_NV50(ScrnInfoPtr pScrn)
nouveau_grobj_alloc(chan, Nv2D, NV50_2D,&pNv->Nv2D) finishes.
BEGIN_RING(chan, eng2d, NV50_2D_DMA_NOTIFY, 3) hangs.
system with blank screen. Can connect with ssh. Card is GeForce 9400 GT

Am game to try to fix - need help.
