Sam Lantinga b8d85c69 2022-11-30T12:51:59 Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594 (cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)

Davis Mosenkovs 66b0a6ee 2021-12-01T01:33:57 workaround for libmali gbm_device_get_fd() gbm_device_get_fd() in at least some libmali versions duplicates handle. Other implementations do not do duplication. To prevent handle leak save drm_fd in SDL_DisplayData.
Anthony Pesch 5a296e25 2021-06-08T20:48:24 kmsdrm: avoid overriding the mode requested by SDL_SetWindowDisplayMode when recreating surfaces
Anthony Pesch fc508eab 2021-05-23T15:59:20 kmsdrm: remove redundant modeset_pending flag this variable was added in commit 2067a7db8e4a36ba40ab34a55b3166ca28638a60 and ultimately tracks if this is a surface's first present. checking if the current bo is NULL provides the same functionality and cuts down on a redundant piece of state potentially getting out of sync in the future
Anthony Pesch 4c965b7a 2021-05-23T16:09:27 kmsdrm: fix SetDisplayMode binding the the wrong surface / context SetDisplayMode needs to recreate the EGL surfaces, which then need to be bound along with the correct context in each rendering thread commit 3a1d7d9c9ac670bf35cfa8ebf3706a1e2a3e5de4 removed this behavior which has broken using SetDisplayMode when rendering with multiple contexts the commit message was rather vague, but if the surfaces do need to be created immediately, this process probably needs to be split such that surface is created immediately, but the binding is deferred
Anthony Pesch fd5de93a 2021-05-23T16:05:39 kmsdrm: fix gbm surface dimensions not matching the mode being set commit 2067a7db8e4a36ba40ab34a55b3166ca28638a60 introduced new surface_w and surface_h variables which were passed to gbm_surface_create rather than the dimensions from the drmModeModeInfo structure. commit 5105ecf8b1b37ab4e4b8344550c90dd69f49909e further refactored this code and no longer synchronized these variables inside KMSDRM_SetDisplayMode, breaking it this change removes the variables since they're seemingly redundant to begin with

Sam Lantinga 3e935aec 2020-02-09T11:44:22 Fixed bug 4966 - KMSDRM: Add dynamic modeset support Anthony Pesch * Remove triple buffering support. As far as I can tell, this goes against the libdrm API; the EGL implementations themselves control the buffering. Removing it isn't absolutely necessary as it seemingly works on the Pi at least, but I noticed this while doing my work and explained my reasoning in the commit. * Replace the crtc_ready logic which allocates an extra bo to perform the initial CRTC configuration (which is required before calling drmModePageFlip) with a call to drmModeSetCrtc after the front and back buffers are allocated, avoiding this allocation. * Standardized the SDL_*Data variable names and null checks to improve readability. Given that there were duplicate fields in each SDL_*Data structure, having generic names such as "data" at times was very confusing. * Removed unused fields from the SDL_*Data structures and moves all display related fields out of SDL_VideoData and into SDL_DisplayData. Not required since the code only supports a single display right now, but this was helpful in reading and understanding the code initially. * Implement KMSDRM_GetDisplayModes / KMSDRM_SetDisplayMode to provide dynamic modeset support. These changes have been tested on a Raspberry Pi 4 and a Dell XPS laptop with an HD 520. As an update, I went back over the triple buffer changes and left them in. I didn't entirely get the code originally, I had just seen it calling KMSDRM_gbm_surface_lock_front_buffer twice for a single swap and had removed it because I was paranoid of bugs stemming from it while working on the modeset changes. I've made a few small changes to the logic that had thrown me off originally and rebased the changes: * The condition wrapping the call to release buffer was incorrect. * The first call to KMSDRM_gbm_surface_lock_front_buffer has been removed. I don't understand why it existed. * Added additional comments describing what was going on in the code (as it does fix the buffer release pattern of the original code before it).

Sam Lantinga 3ac9e2aa 2018-10-05T17:06:05 Fixed bug 4296 - kmsdrm video driver leaks 1 bo in KMSDRM_GLES_SetupCrtc() Icenowy Zheng One front buffer is locked in GLES_SetupCrtc() and overrides the next_bo just locked in KMSDRM_GLES_SwapWindow, then the next_bo gets lost and is not released even when quitting the video. It may leads to problems with GLES drivers that doesn't clean up GBM correctly if there's any bo left (e.g. the Mali Utgard r6p2 blob). In the case of Mali Utgard r6p2 blob, the DRM device file is still hold by the blob, and if you try to SDL_Quit to let another program to run (this is done by EmulationStation), the new program will fail to open DRM device.

Sam Lantinga 8758b7bf 2017-11-24T12:03:28 Fixed bug 3980 - Fix for KMSDRM driver where cursor would not be shown on some gfx hardware because of unsupported cursor size Manuel Alfayate Corchete This fixes a problem with KMSDRM on some graphics hardware where only bigger cursor sizes are supported, such as current Intel gfx. (The kernel-side driver is what limits this: had to look for failing IOCTLs...) That caused SDL_SetCursor() to fail silently, and we were left with a missing cursor without further explanation. With this patch, different "standard" sizes are tried and a bigger one is used (with an intermediate and clean buffer only used to write the new cursor to the BO where it will live after) if we get, let's say, 16x16 which is pretty common but our hardware does not support that.
Brandon Schaefer 2ac567b7 2017-10-26T16:37:20 Fixed bug 3902 - Add a specific KMSDRM hint for low latency video
Sam Lantinga 10376eb9 2017-10-21T04:20:57 Fixed bug 3901 - Fix vsync-ed pageflips on the KMSDRM video driver Manuel I noticed that, at least on Intel GPU hardware, passing SDL_RENDERER_PRESENTVSYNC would result on a static console instead of the program graphics. That was due to the fact that calling drmModePageFlip() only works if we have previously set up CRTC to one of the GBM buffers with a drmModeSetCrtc() call, so now it's done and things work as expected. The KMSDRM_GLES_SetupCrtc() call is done only one time, only when needed (when egl_swapinterval is not 0: when it's 0, there's no need for it because we flip by calling drmModePageFlip() anyway). The place where KMSDRM_GLES_SetupCrtc() call is done may look strange, but it's right: it needs EGL completely ready because it needs to call eglSwapBuffers() internally to work (see more comments about it in the code).

Sam Lantinga 56363ebf 2017-08-02T10:22:48 Fixed bug 3690 - SDL2 KMS/DRM render context support Manuel The attached patch adds support for KMS/DRM context graphics. It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation. Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition. X86 systems use KMS right away in every current GNU/Linux system. Simple build instructions: $./autogen.sh $./configure --enable-video-kmsdrm $make
