Hi Marek,
actually I was on the verge to remove the 32bit VM support in libdrm
because it clashes with HMM and SVM in general.
Is it possible to set the upper 32bit of the 64bit address to some fixed
value instead?
Regards,
Christian.

Hi,
This series:
- increases the number of buckets in pb_cache
- adds 32-bit heaps: GTT WC, VRAM, and read-only versions of those
- adds a 32-bit VM allocator into winsys/radeon and enables 32-bit VM
allocations in both winsyses
- moves all const_uploader allocations to 32-bit address space
- puts "amdgpu.uniform" LLVM metadata on loads instead of GEPs,
so that InstCombine doesn't remove it
- switches shader pointers in user SGPRs to 32 bits
Dependencies:
- https://reviews.llvm.org/D41715
- https://reviews.llvm.org/D41651
This frees up to 7 user SGPRs in merged shaders, 5 user SGPRs
in vertex shaders, and 4 user SGPRs in other shaders.
Please review.
Thanks,
Marek
