[PATCH 0/7] MR2712: winewayland.drv: part 3: Handle dynamic wl_output events
by Alexandros Frantzis (＠afrantzis) 28 Apr '23

28 Apr '23

This MR introduces the driver mechanisms to handle dynamic events from the Wayland compositor, using wl_output events as the guiding use case (i.e., we want to update the win32u display settings when the host settings change). In this design we create a dedicated thread to read and dispatch Wayland events received from the compositor. If a Wayland event handler wants some code to be run in the context of a particular HWND's thread, it can add an internal event to a custom queue we have for each (GUI enabled) thread. The ProcessEvents driver callback processes internal events from that queue. In order to wake up waiting threads we use a pipe to notify about new internal events, with the read end acting as the thread's host queue fd. This is similar to how winemac.drv works. We use the aforementioned mechanisms to queue win32u display device updates to the desktop window thread. Since there are many pieces that need to fall into place, this MR gradually reaches the final design: 1. We first introduce the dedicated read/dispatch thread and handle events (and also display device updates if in the desktop process) in that thread. 2. We ensure access to Wayland output information is thread-safe and consistent (since in step 3 we will need to access it from a different thread). 3. We finally introduce per-thread internal event queues and, if we are in the desktop process, queue the display device update to the desktop window thread internal event queue. Note that the main portion of the wl_output event code is still handled in the dedicated read/dispatch thread. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2712

[PATCH v5 0/2] MR184: vkd3d-shader/hlsl: Add support for SampleGrad() method
by Ethan Lee (＠flibitijibibo) 28 Apr '23

28 Apr '23

~~This one's marked as a draft, as there seems to be a blocker with the method parameters.~~ ~~The first commit totally works, _if_ the ddx/ddy parameters are literals - they do _not_ work when passing a variable of any kind. The test comes from tests/d3d12.c, so I'm mostly just trying to migrate that to the HLSL test suite, but it currently hits an assert before we get to the resource load (which does eventually work) and I'm not sure what's causing it:~~ ``` vkd3d-compiler: libs/vkd3d-shader/tpf.c:3190: sm4_register_from_node: Assertion `instr->reg.allocated' failed. ``` ~~Seems like it's surprised when we try to load from the constant buffer maybe?~~ Fixed! -- v5: tests: Add a basic compilation test for SampleGrad() method. vkd3d-shader/hlsl: Add support for SampleGrad() method https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/184

[PATCH v6 0/2] MR179: vkd3d-shader/hlsl: Add support for ddx(), ddy() intrinsics.
by Ethan Lee (＠flibitijibibo) 28 Apr '23

28 Apr '23

SPIR-V already handled DSX/DSY, so only D3DBC/TPF needed new case blocks. You'll notice that there's no test for this one - in addition to being a pretty straightforward translation for all possible formats, this feature uses the render target width/height and I wasn't sure if there was a good way to ensure that the test would always make sense. Instead, I did the test manually, and it's what you'd expect (EDIT: Previously the test used a uniform which always optimized to 0, new test uses VPOS instead): HLSL: ``` float4 main(float4 pos : sv_position) : sv_target { float4 x = ddx(pos.x); float4 y = ddy(pos.y); return x + y; } ``` D3DBC: ``` ps_3_0 dcl_position0 vPos mov r0.xyzw, vPos.xyzw mov r1.x, r0.x dsx r1.x, r1.x mov r0.x, r0.yxxx dsy r0.x, r0.x mov r1.xyzw, r1.x mov r0.xyzw, r0.x add r0.xyzw, r1.xyzw, r0.xyzw mov oC0.xyzw, r0.xyzw ``` DXBC-TPF: ``` ps_4_0 dcl_input_ps_siv linear v0.xyzw, position dcl_output o0.xyzw dcl_temps 2 mov r0.xyzw, v0.xyzw mov r1.x, r0.x dsx r1.x, r1.x mov r0.x, r0.yxxx dsy r0.x, r0.x mov r1.xyzw, r1.x mov r0.xyzw, r0.x add r0.xyzw, r1.xyzw, r0.xyzw mov o0.xyzw, r0.xyzw ret ``` Fixes https://bugs.winehq.org/show_bug.cgi?id=54827 -- v6: tests: Add tests for ddx(), ddy() intrinsics. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/179
