* virgl: Use virgl_staging_mgrAlexandros Frantzis2019-06-281-2/+3
| | | | | | | | | | Use an instance of virgl_staging_mgr instead of u_upload_mgr to handle the staging buffer. This removes the need to track the availability of the staging manager, since virgl_staging_mgr can handle concurrent active allocations.

* virgl: add virgl_rebind_resourceChia-I Wu2019-06-171-0/+8
| | | | | | | | | We are going support reallocating the HW resource for a virgl_resource. When that happens, the virgl_resource needs to be rebound to the context. Signed-off-by: Chia-I Wu <[email protected]> Reviewed-by: Alexandros Frantzis <[email protected]>
* virgl: Work around possible memory exhaustionAlexandros Frantzis2019-06-071-0/+3
| | | | | | | | | | | | | | | | | | | | | Since we don't normally flush before performing copy transfers, it's possible in some scenarios to use too much memory for staging resources and start failing. This can happen either because we exhaust the total available memory (including system memory virtio-gpu swaps out to), or, more commonly, because the total size of resources in a command buffer doesn't fit in virtio-gpu video memory. To reduce the chances of this happening, force a flush before a copy transfer if the total size of queued staging resources exceeds a certain limit. Since after a flush any queued staging resources will be eventually released, this ensures both that each command buffer doesn't require too much video memory, and that we don't end up consuming too much memory for staging resources in total. Fixes kernel errors reported when running texture_upload tests in glbench. Signed-off-by: Alexandros Frantzis <[email protected]> Reviewed-by: Chia-I Wu <[email protected]>
* virgl: Use buffer copy transfers to avoid waiting when mappingAlexandros Frantzis2019-06-071-0/+2
| | | | | | | | | | | | | | | | | | | | We typically need to wait for a buffer to become ready before mapping, so that we don't write new contents while the host is still using the old contents. However, if we are allowed to discard the contents of the mapped buffer range, then we can avoid waiting by using a staging buffer range which we guarantee to never be busy, copying from the staging buffer range to the target buffer in the host. This commit implements this optimization by utilizing a dedicated u_upload_mgr for the staging buffer.

| | | | | | | | | | | | | | virgl_shader_binding_state will be used to manage all per-stage shader bindings. For now, it manages only sampler views. This replaces virgl_textures_info and fixes some issues - start_slot is now honored - views outside of [start_slot, slart_slot+count) are unmodified - views are released when the context is destroyed Signed-off-by: Chia-I Wu <[email protected]> Reviewed-by: Alexandros Frantzis <[email protected]>

* virgl: modify how we handle GL_MAP_FLUSH_EXPLICIT_BITGurchetan Singh2018-12-191-1/+0
| | | | | | | | | | | | | | | | | | Previously, we ignored the the glUnmap(..) operation and flushed before we flush the cbuf. Now, let's just flush the data when we unmap. Neither method is optimal, for example: glMapBufferRange(.., 0, 100, GL_MAP_FLUSH_EXPLICIT_BIT) glFlushMappedBufferRange(.., 25, 30) glFlushMappedBufferRange(.., 65, 70) We'll end up flushing 25 --> 70.

* virgl: add driver for virtio-gpu 3D (v2)Dave Airlie2015-10-231-0/+100
virgl is the 3D acceleration backend for the virtio-gpu shipping with qemu. The 3D acceleration is designed around gallium and TGSI as the virtualisation layer. The backend renderer translates the virgl interface into OpenGL currently. This is the initial import of the driver to mesa. The kernel driver portions are lined up for drm-next. Currently this driver supports up to GL3.3 and some misc extensions if the host driver exposes it. It is planned to iterate the virgl API to new GL levels as mesa host drivers gain features. v2: fix resource tracking across flushes to avoid ->bind hack in mapping. consolidate mapping and waiting code for transfers. use u_range for dirt tracking. handle larger shaders in protocol. include virtgpu_drm.h in mesa for now. add translation layer for gallium tgsi to virgl tgsi.
