hi, With XEN enabled in mainline kernel 2.6.37 configured for nouveau, X failed with familiar symptoms. Found drm-tree did not have the TTM_MEMTYPE_FLAG_NEEDS_IOREMAP or the drm_scatter patches. Applied these patches (generated from my working 2.6.32.18 xen kernel with 2.6.35.4 drm-tree backported) to the 2.6.37 mainline kernel. Now starting X in dom0 invokes the OOM killer! Bare boot works, as usual. Any suggestions? Arvind. ________________________________...

...lso please pull from devel/kms.fixes-05 (based off your xen/dom0/agp) which has the following patches: Daniel De Graaf (1): fb: propagate VM_IO to VMA. Konrad Rzeszutek Wilk (10): ttm: When TTM_PAGE_FLAG_DMA32 allocate pages under 4GB under Xen. ttm: Set VM_IO only on pages with TTM_MEMTYPE_FLAG_NEEDS_IOREMAP set. agp: Use Xen back-door to get bus address for legacy code. agp: Program the GART with the real physical address under Xen. agp: If _GFP_DMA_32 flag is set enforce pages to be under 4GB under Xen. agp-backend: Use Xen back-door to get bus address for scratch page....

Hi, Following is a simple patch that is needed in nouveau to get accelerated X on a Xen dom0 pv_ops kernel. The kernel is jeremy's 2.6.31.6 as of 20100222. The whole gpu tree of nouveau (which is almost the mainline merge), was substituted into the kernel-tree. All components of X (mesa, Xorg-server-7.5, xf86-nouveau, libdrm) used of the same day. Patch: diff -Naur
