anv/trtt: set every entry to NULL when we create an L2 table When we create sparse resources the first thing we do is a NULL bind on them, as the Vulkan spec mandates certain behavior even for unbound sparse resources. We do this with the minimal effort possible: if we can get away with marking an L2 pointer as NULL in the L3 table, we just do it and return, instead of going all the way to creating L1 tables and marking all the final entries as NULL. The strategy we were using had a bug that could lead to previously created NULL entries not being marked as NULL anymore. Let's give an example: (before proceeding, keep in mind that a NULL entry in the L3 and L2 tables has bit 1 set, it does *not* have the value 0) - Create a 64mb buffer that uses an entire L1 table (needs to be properly aligned), which triggers a NULL bind. - Our algorithm will just set the L3 entry (pointing to the L2 table) as NULL. - Create a 64kb buffer that uses the same L2 table (but a different L1 table). - The NULL bind triggered won't do anything as the L2 table is already NULL. - Bind the first buffer to actual memory. This will end up creating the L2 table and the L1 table. The only entry we will set in the L2 table will be the one pointing to the L1 table. All the other values will be 0 (so they won't have neither the NULL or Invalid bits set: access to them will lead to page faults). - Try to use the second buffer, which is still unbound. It was relying on the fact that its L2 table pointer was NULL, but now it's not anymore, so the page walker will fetch the L1 entries in the L2 table and they will all be zero instead of having the NULL bit set. The fix is pretty simple: whenever we create a new L2 table, set every entry to NULL (except the one we're about to set to non-NULL). This preserves behavior for every other NULL resource relying on the L3 entry being set to NULL. We don't need to do this for the L1 table because its entries are different and instead of having bits to signal NULL entries we have a special TR-TT register that we can set that gets compared to check if an entry is NULL, and we conveniently program it to 0: see ANV_TRTT_L1_NULL_TILE_VAL. I am not aware of any real workloads that are triggering this behavior, I found this issue while investigating something else, running a custom sparse program in our pre-silicon environment, and it told us about the page faults.

anv/trtt: set every entry to NULL when we create an L2 table When we create sparse resources the first thing we do is a NULL bind on them, as the Vulkan spec mandates certain behavior even for unbound sparse resources. We do this with the minimal effort possible: if we can get away with marking an L2 pointer as NULL in the L3 table, we just do it and return, instead of going all the way to creating L1 tables and marking all the final entries as NULL. The strategy we were using had a bug that could lead to previously created NULL entries not being marked as NULL anymore. Let's give an example: (before proceeding, keep in mind that a NULL entry in the L3 and L2 tables has bit 1 set, it does *not* have the value 0) - Create a 64mb buffer that uses an entire L1 table (needs to be properly aligned), which triggers a NULL bind. - Our algorithm will just set the L3 entry (pointing to the L2 table) as NULL. - Create a 64kb buffer that uses the same L2 table (but a different L1 table). - The NULL bind triggered won't do anything as the L2 table is already NULL. - Bind the first buffer to actual memory. This will end up creating the L2 table and the L1 table. The only entry we will set in the L2 table will be the one pointing to the L1 table. All the other values will be 0 (so they won't have neither the NULL or Invalid bits set: access to them will lead to page faults). - Try to use the second buffer, which is still unbound. It was relying on the fact that its L2 table pointer was NULL, but now it's not anymore, so the page walker will fetch the L1 entries in the L2 table and they will all be zero instead of having the NULL bit set. The fix is pretty simple: whenever we create a new L2 table, set every entry to NULL (except the one we're about to set to non-NULL). This preserves behavior for every other NULL resource relying on the L3 entry being set to NULL. We don't need to do this for the L1 table because its entries are different and instead of having bits to signal NULL entries we have a special TR-TT register that we can set that gets compared to check if an entry is NULL, and we conveniently program it to 0: see ANV_TRTT_L1_NULL_TILE_VAL. I am not aware of any real workloads that are triggering this behavior, I found this issue while investigating something else, running a custom sparse program in our pre-silicon environment, and it told us about the page faults.

anv/xe: try harder when the vm_bind ioctl fails From all the many possible errors returned by the vm_bind ioctl, some can actually happen in the wild when the system is under memory pressure. Thomas Hellström pointed to us that, due to its asynchronous nature, the vm_bind ioctl itself has to pin some memory, so if the number of bind operations passed is too big, there is a probability that it may run out of memory. Previously the Kernel would return ENOMEM when this condition happened. Since commit e8babb280b5e ("drm/xe: Convert multiple bind ops into single job") the Kernel has started returning ENOBUFS when it doesn't have enough memory to do what it wants but thinks we'd succeed if we tried to do one bind operation at a time (instead of doing multiple operations in the same ioctl), and ENOMEM in some other situations. Still-uncommitted commit "drm/xe: Return -ENOBUFS if a kmalloc fails which is tied to an array of binds" proposes converting a few more ENOMEM cases no ENOBUFS. Still, even ENOMEM situations could in theory be possible to recover from, because if we wait some amount of time, resources that may have been consuming memory could end up being freed by other threads or processes, allowing the operations to succeed. So our main idea in this patch is that we treat both ENOMEM and ENOBUFS in the same way, so our implementation can work with any xe.ko driver regardless of having or not having the commits mentioned above. So in this patch, when we detect the system is under memory pressure (i.e., the vm_bind() function returns VK_ERROR_OUT_OF_HOST_MEMORY), we throw away our performance expectations and try to go slowly and steady. First we wait everything we're supposed to wait (hoping that this alone could also help to alleviate the memory pressure), and then we synchronously bind one piece at a time (as this will ensure ENOBUFS can't be returned), hoping that this won't cause the Kernel to try to reserve too much memory. All this while also hoping that whatever thing that may be eating all the memory goes away in the meantime. If even this fails, we give up and hope the upper layer will be able to figure out what to do. This fixes a bunch of LNL failures and flaky tests (as LNL is our first officially supported xe.ko platform). This can be seen in dEQP but only if multiple tests are being run parallel. Happens in multiple tests, some of which may include: - dEQP-VK.sparse_resources.image_sparse_binding.2d_array.rgba8_snorm.1024_128_8 - dEQP-VK.sparse_resources.image_sparse_binding.3d.rgba16_snorm.1024_128_8 - dEQP-VK.sparse_resources.image_sparse_binding.3d.rgba16ui.512_256_6 I don't ever see these errors when running Alchemist/DG2 with xe.ko.

anv/sparse: replace device->using_sparse with device->num_sparse_resources The device->using_sparse variable is only used at cmd_buffer_barrier() to decide if we need to apply the heavier-weight flushes that are only applicable to sparse resources. The big problem here is that we need to apply the flushes to the non-image and non-buffer memory barriers, so we were trying to limit those only to applications that ever submit a sparse resource to the sparse queue. The reason why we were applying this only to devices that ever submitted sparse resources is that dxvk games have this thing where during startup they create and then delete tiny sparse resources, so switching device->using_sparse to true at resource creation would make basically every dxvk game start applying the heavier-weight workaround. The problem with all that is that even if an application creates a sparse resource but doesn't ever bind them, the resource should still behave as an unbound resource (because they are bound with a NULL bind), so the flushes affecting them should happen.

anv/sparse: replace device->using_sparse with device->num_sparse_resources The device->using_sparse variable is only used at cmd_buffer_barrier() to decide if we need to apply the heavier-weight flushes that are only applicable to sparse resources. The big problem here is that we need to apply the flushes to the non-image and non-buffer memory barriers, so we were trying to limit those only to applications that ever submit a sparse resource to the sparse queue. The reason why we were applying this only to devices that ever submitted sparse resources is that dxvk games have this thing where during startup they create and then delete tiny sparse resources, so switching device->using_sparse to true at resource creation would make basically every dxvk game start applying the heavier-weight workaround. The problem with all that is that even if an application creates a sparse resource but doesn't ever bind them, the resource should still behave as an unbound resource (because they are bound with a NULL bind), so the flushes affecting them should happen. This case is exercised by vkd3d-proton/test_buffer_feedback_instructions_sm51. In order to satisfy all the above cases and only really apply the heavier-weight flushes to applications actually using sparse resources, let's just count the number of sparse resources that currently exist and then apply the workaround only if it's not zero.

anv/sparse: reject 1D sparse residency images The Vulkan spec splits sparse resources in two different features: sparse binding and sparse residency. Sparse binding is much simpler. It requires the resources to be fully bound before being used and it treats them as a black box. We're required to support sparse binding for all the formats that are supported by non-sparse, but that's easy beacause this feature is simpler. Now sparse residency is the one where we're allowed to partially bind resources, and the one that comes with more complicated features such as block shapes and non-opaque binding of images. This feature is subdivided into: - sparseResidencyBuffer - sparseResidencyImage2D - sparseResidencyImage3D - sparseResidency{2,4,8,16}Samples (which refers to 2D images) Notice that there's no sparseResidencyImage1D. And if you read the specs it's clear that sparse residency is meant for non-1D images. Still, supporting it didn't require any extra effort in Anv so we just did it. That's until we started running GL CTS tests on Zink. There's a CTS test that checks for the standard block shapes. It creates 1D images and expects the block shapes for them to be the standard 2D block shapes. While we could very well just patch anv_sparse_calc_image_format_properties() to return the standard 2D block shapes for 1D images, that's just wrong (block shapes for 1D images are just line segments, not rectangles!) so let's just reject this all until maybe one day Vulkan defines sparseResidencyImage1D and we get GL_ARB_sparse_texture3 to match it, or somebody decides to change the GL CTS test.

anv/sparse: don't support YCBCR 2x1 compressed formats Regarding supporting these formats, the spec says: "A sparse image created using VK_IMAGE_CREATE_SPARSE_RESIDENCY_BIT supports all non-compressed color formats with power-of-two element size that non-sparse usage supports. Additional formats may also be supported and can be queried via vkGetPhysicalDeviceSparseImageFormatProperties. VK_IMAGE_TILING_LINEAR tiling is not supported." Regarding the formats themselves, the spec says: "VK_FORMAT_B8G8R8G8_422_UNORM specifies a four-component, 32-bit format containing a pair of G components, an R component, and a B component, collectively encoding a 2×1 rectangle of unsigned normalized RGB texel data. One G value is present at each i coordinate, with the B and R values shared across both G values and thus recorded at half the horizontal resolution of the image. This format has an 8-bit B component in byte 0, an 8-bit G component for the even i coordinate in byte 1, an 8-bit R component in byte 2, and an 8-bit G component for the odd i coordinate in byte 3. This format only supports images with a width that is a multiple of two. For the purposes of the constraints on copy extents, this format is treated as a compressed format with a 2×1 compressed texel block." Since these formats are to be considered compressed 2x1 blocks and we don't necessarily have to support non-compressed formats that non-sparse support, we can claim them as not supported with sparse. In addition to all of that, if you look at isl_gfx125_filter_tiling() you'll see that we don't even support Tile64 for these formats, so sparse residency (i.e., non-opaque image binds) doesn't really make sense for them yet. The Vulkan spec defines 4 other YCBCR "2x1 compressed" formats like the ones we have in this commit, but we don't support them even without sparse, so there's no reason to check them here. A recent change in VK-GL-CTS made tests that use these formats go from unsupported to failures: 7ecc7716a983 ("Do not use and check for STORAGE image support, when it is not used in the test") This commit "fixes" the following VK-GL-CTS failures (by making them return NotSupported): dEQP-VK.sparse_resources.image_block_shapes.2d.b8g8r8g8_422_unorm.samples_1 dEQP-VK.sparse_resources.image_block_shapes.2d.g8b8g8r8_422_unorm.samples_1 dEQP-VK.sparse_resources.image_block_shapes.2d_array.b8g8r8g8_422_unorm.samples_1 dEQP-VK.sparse_resources.image_block_shapes.2d_array.g8b8g8r8_422_unorm.samples_1 Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25512>
