We unfortunately didn't knew that initially and also didn't used the ATC, so we didn't ran into a problem. But ROCm now uses the ATC on Raven/Picasso and I have a branch where I enable it on Vega as well. So when we don't fix that we will run into problems here. The ATC isn't usable in combination with SRIOV and I don't think Windows uses it either, so they probably never ran into any issues. <blockquote type="cite">Do you mean even UMD should not use virtual address that dropped in range from 0 to HOLE_START ?</blockquote> Yes, exactly! That in combination with ATC use can have quite a bunch of strange and hard to track down effects because two parts of the driver are using the same address space. <blockquote type="cite">That way where should UMD work in ?and I assume our UMD now still using this range, this part make me puzzle </blockquote> At least Mesa now uses the high address space from HOLE_END..0xFFFF FFFF FFFF FFFF. </div> </blockquote> That is why there is high_vamgr in libdrm. The extended va will be masked in kernel when doing vm mapping, right? If mesa already switches to use that, shouldn't internal opengl and vulkan switch to? -David <blockquote type="cite" cite="mid:c83cd7ec-03a5-45c0-b497-d5a5ec838880@gmail.com"> <div class="moz-cite-prefix"> Regards, Christian.

The GMC manages a virtual 64bit address space, but only 48bit of that virtual address space are handled by the page table walker. The 48bits of address space are sign extended, so bit 47 of that are extended into bits 48-63. This gives us the following memory layout: 0x0 .... virtual address space 0x8000 0000 0000 .... hole 0xFFFF 8000 0000 0000 .... virtual address space 0xFFFF FFFF FFFF FFFF Trying to access the hole results in a range fault interrupt IIRC. When doing the VM page table walk the topmost 16bits are ignored, so when programming the page table walker you cut those of and use a linear address again. This is what AMDGPU_GMC_HOLE_MASK is good for. Now on Vega/Raven/Picasso etc.. (everything with a GFX9) the lower range (0x0-0x8000 0000 0000) is reserved for SVA/ATC use. Since we unfortunately didn't knew that initially we exposed those to older userspace as usable and also put the CSA in there. The most likely cause of this is that we still have a bug somewhere about this, e.g. not correctly using sign extended addresses *OR* using sign extended addresses where we should use linear instead.

See the engines see an MC address space with a hole in the middle, similar to the how x86 64bit CPU address space works. But the page tables are programmed linearly. So the calculation in amdgpu_driver_open_kms() is correct because it takes the MC address and mages a linear page table index from it again. The only thing we might need to fix here is shifting max_pfn before the subtraction and I doubt that even that is necessary. Regards, Christian.
