2013-08-31drm/radeon: default to 1024M gart size on rv770+Alex Deucher1-2/+2
Newer asics have a lot of vram so it's less of an issue to waste a little more space for the gart page table. This gives us some additional gart space before having to migrate to non-gart system ram for games, etc. where we use up most of vram. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

This patch allows the CPU to map the stolen vram segment directly rather than going through the PCI BAR. This significantly improves performance for certain workloads with a properly patched ddx.

2013-03-07drm/radeon: don't check mipmap alignment if MIP_ADDRESS is FMASKMarek Olšák1-1/+2
The MIP_ADDRESS state has 2 meanings. If the texture has one sample per pixel, it's a pointer to the mipmap chain.

2012-06-10drm/radeon: fix tiling and command stream checking on evergreen v3Jerome Glisse1-1/+2
Fix regresson since the introduction of command stream checking on evergreen (thread referenced below). Issue is cause by ddx allocating bo with formula width*height*bpp while programming the GPU command stream with ALIGN(height, 8). In some case (where page alignment does not hide the extra size bo should be according to height alignment) the kernel will reject the command stream. This patch reprogram the command stream to slice - 1 (slice is a derivative value from height) which avoid rejecting the command stream while keeping the value of command stream checking from a security point of view. This patch also fix wrong computation of layer size for 2D tiled surface. Which should fix issue when 2D color tiling is enabled. This dump the radeon KMS_DRIVER_MINOR so userspace can know if they are on a fixed kernel or not. https://lkml.org/lkml/2012/6/3/80 https://bugs.freedesktop.org/show_bug.cgi?id=50892 https://bugs.freedesktop.org/show_bug.cgi?id=50857 !!!

2012-01-06drm/radeon: GPU virtual memory support v22Jerome Glisse1-1/+8
Virtual address space are per drm client (opener of /dev/drm). Client are in charge of virtual address space, they need to map bo into it by calling DRM_RADEON_GEM_VA ioctl. First 16M of virtual address space is reserved by the kernel. Once using 2 level page table we should be able to have a small vram memory footprint for each pt (there would be one pt for all gart, one for all vram and then one first level for each virtual address space). Plan include using the sub allocator for a common vm page table area and using memcpy to copy vm page table in & out. Or use a gart object and copy things in & out using dma. v2: agd5f fixes: - Add vram base offset for vram pages. The GPU physical address of a vram page is FB_OFFSET + page offset. FB_OFFSET is 0 on discrete cards and the physical bus address of the stolen memory on integrated chips. - VM_CONTEXT1_PROTECTION_FAULT_DEFAULT_ADDR covers all vmid's >= 1 v3: agd5f: - integrate with the semaphore/multi-ring stuff v4: - rebase on top ttm dma & multi-ring stuff - userspace is now in charge of the address space - no more specific cs vm ioctl, instead cs ioctl has a new chunk v5: - properly handle mem == NULL case from move_notify callback - fix the vm cleanup path v6: - fix update of page table to only happen on valid mem placement v7: - add tlb flush for each vm context - add flags to define mapping property (readable, writeable, snooped) - make ring id implicit from ib->fence->ring, up to each asic callback to then do ring specific scheduling if vm ib scheduling function v8: - add query for ib limit and kernel reserved virtual space - rename vm->size to max_pfn (maximum number of page) - update gem_va ioctl to also allow unmap operation - bump kernel version to allow userspace to query for vm support v9: - rebuild page table only when bind and incrementaly depending on bo referenced by cs and that have been moved - allow virtual address space to grow - use sa allocator for vram page table - return invalid when querying vm limit on non cayman GPU - dump vm fault register on lockup v10: agd5f: - Move the vm schedule_ib callback to a standalone function, remove the callback and use the existing ib_execute callback for VM IBs. v11: - rebase on top of lastest Linus v12: agd5f: - remove spurious backslash - set IB vm_id to 0 in radeon_ib_get() v13: agd5f: - fix handling of RADEON_CHUNK_ID_FLAGS v14: - fix va destruction - fix suspend resume - forbid bo to have several different va in same vm v15: - rebase v16: - cleanup left over of vm init/fini v17: agd5f: - cs checker v18: agd5f: - reworks the CS ioctl to better support multiple rings and VM.

2011-11-20drm/radeon/kms: add a CS ioctl flag not to rewrite tiling flags in the CSMarek Olšák1-1/+2
This adds a new optional chunk to the CS ioctl that specifies optional flags to the CS parser. Why this is useful is explained below. Note that some regs no longer need the NOP relocation packet if this feature is enabled. Tested on r300g and r600g with this flag disabled and enabled. Assume there are two contexts sharing the same mipmapped tiled texture. One context wants to render into the first mipmap and the other one wants to render into the last mipmap. As you probably know, the hardware has a MACRO_SWITCH feature, which turns off macro tiling for small mipmaps, but that only applies to samplers. (at least on r300-r500, though later hardware likely behaves the same) So we want to just re-set the tiling flags before rendering (writing packets), right? ... No. The contexts run in parallel, so they may set the tiling flags simultaneously and then fire their command streams also simultaneously. The last one setting the flags wins, the other one loses. Another problem is when one context wants to render into the first and the last mipmap in one CS. Impossible. It must flush before changing tiling flags and do the rendering into the smaller mipmaps in another CS. Yet another problem is that writing copy_blit in userspace would be a mess involving re-setting tiling flags to please the kernel, and causing races with other contexts at the same time. The only way out of this is to send tiling flags with each CS, ideally with each relocation. But we already do that through the registers. So let's just use what we have in the registers.

2011-11-11drm: Make the per-driver file_operations struct constArjan van de Ven1-29/+31
From fdf1fdebaa00f81de18c227f32f8074c8b352d50 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven <arjan@linux.intel.com> Date: Sun, 30 Oct 2011 19:06:07 -0700 Subject: [PATCH] drm: Make the per-driver file_operations struct const The DRM layer keeps a copy of struct file_operations inside its big driver struct... which prevents it from being consistent and static. For consistency (and the general security objective of having such things static), it's desirable to get this fixed. This patch splits out the file_operations field to its own struct, which is then "static const", and just stick a pointer to this into the driver struct, making it more consistent with how the rest of the kernel does this.

2011-11-03drm/radeon/kms: add MSI module parameterAlex Deucher1-0/+4
Allow the user to override whether MSIs are enabled or not on supported ASICs. MSIs are disabled by default on IGP chips as they tend not to work. However certain IGP chips only seem to work with MSIs enabled. I suspect this is a chipset or bios issue, but I'm not sure what the proper fix is. This will at least make diagnosing and working around the problem much easier.
