| | | | | | | | When a buffer becomes resident, check if it has been invalidated, if so update the descriptor and the dirty flag. Signed-off-by: Samuel Pitoiset <[email protected]> Reviewed-by: Marek Olšák <[email protected]>
* radeonsi: upload new descriptors when resident buffers are invalidatedSamuel Pitoiset2017-06-143-0/+152
| | | | | | | | | | | | | When texture buffers are invalidated the addr in the resident descriptor has to be updated but we can't create a new descriptor because the resident handle has to be the same. Instead, use the WRITE_DATA packet which allows to update memory directly but graphics/compute have to be idle in case the GPU is reading the descriptor.

* radeonsi: only decompress resident textures/images when usedSamuel Pitoiset2017-06-141-2/+11

| | | | | | | | | | Analogous to bound textures/images. We should also update the resident descriptors and disable COMPRESSION_EN for avoiding useless DCC fetches, but I postpone this optimization for a separate series.

* radeonsi: add all resident buffers to the current CSSamuel Pitoiset2017-06-143-0/+52
| | | | | | | | | | | Resident buffers have to be added to every new command stream. Though, this could be slightly improved when current shaders don't use any bindless textures/images but usually applications tend to use bindless for almost every draw call, and the winsys thread might help when buffers are added early.

* radeonsi: add a slab allocator for bindless descriptorsSamuel Pitoiset2017-06-144-0/+119
| | | | | | | | | | | | | | | | | | | For each texture/image handles, we need to allocate a new buffer for the bindless descriptor. But when the number of buffers added to the current CS becomes high, the overhead in the winsys (and in the kernel) is important. To reduce this bottleneck, the idea is to suballocate the bindless descriptors using a slab similar to the one used in the winsys. Currently, a buffer can hold 1024 bindless descriptors but this limit is arbitrary and could be changed in the future for some reasons. Once a slab is allocated the "base" buffer is added to a per-context list. Signed-off-by: Samuel Pitoiset <[email protected]> Reviewed-by: Marek Olšák <[email protected]>

| | | | | | | | | | | | | | | | | | | The ARB_bindless_texture spec say: "If ARB_seamless_cubemap (or OpenGL 4.0, which includes it) is supported, the per-context seamless cubemap enable is ignored and treated as disabled when using texture handles." "If AMD_seamless_cubemap_per_texture is supported, the seamless cube map texture parameter of the underlying texture does apply when texture handles are used." The per-context seamless cubemap flag should only be enabled for bound textures/samplers.

| | | | | | | | | | | | | | | | | | | Yes, ARB_bindless_texture allows to do this. In other words, in a situation like: layout (bindless_sampler) uniform sampler2D tex; The 'tex' sampler uniform can be either set with glUniform1() (old-style bound samplers) or with glUniformHandleui() (resident handles). When glUniform1() is used, we have to somehow make the texture resident "under the hood". This is done by requesting a texture handle to the driver, making the handle resident in the current context and overwriting the value directly in the constant buffer.
