cd2eb57d - drm/vmwgfx: Implement virtual kms

Fri, 12 Apr 2024 02:55:07 +0000

drm/vmwgfx: Implement virtual kmsBy default vmwgfx doesn't support vblanking or crc generation whichmakes it impossible to use various IGT tests to validate vmwgfx.Implement virtual kernel mode setting, which is mainly related tosimulated vblank support.Code is very similar to amd's vkms and the vkms module itself, exceptthat it's integrated with vmwgfx three different output technologies -legacy, screen object and screen targets.Make IGT's kms_vblank pass on vmwgfx and allows a lot of other IGTtests to run with vmwgfx.Support for vkms needs to be manually enabled by adding:guestinfo.vmwgfx.vkms_enable = "TRUE"somewhere in the vmx file, otherwise it's off by default.Signed-off-by: Zack Rusin Acked-by: Martin Krastev Link: https://patchwork.freedesktop.org/patch/msgid/20240412025511.78553-2-zack.rusin@broadcom.com List of files: /linux-6.15/drivers/gpu/drm/vmwgfx/Makefile

Tue, 31 Jan 2023 03:35:35 +0000

drm/vmwgfx: Use the common gem mmap instead of the custom codeBefore vmwgfx supported gem it needed to implement the entire mmap logicexplicitly. With GEM support that's not needed and the generic codecan be used by simply setting the vm_ops to vmwgfx specific ones on thegem object itself.Removes a lot of code from vmwgfx without any functional difference.Signed-off-by: Zack Rusin Reviewed-by: Thomas Zimmermann Reviewed-by: Martin Krastev Reviewed-by: Maaz Mombasawala Link: https://patchwork.freedesktop.org/patch/msgid/20230131033542.953249-2-zack@kde.org List of files: /linux-6.15/drivers/gpu/drm/vmwgfx/Makefile

df42523c - drm/vmwgfx: Port the framebuffer code to drm fb helpers

Sat, 22 Oct 2022 04:02:32 +0000

drm/vmwgfx: Port the framebuffer code to drm fb helpersInstead of using vmwgfx specific framebuffer implementation use the drmfb helpers. There's no change in functionality, the only differenceis a reduction in the amount of code inside the vmwgfx module.drm fb helpers do not deal correctly with changes in crtc preferred modeat runtime, but the old fb code wasn't dealing with it either.Same situation applies to high-res fb consoles - the old code waslimited to 1176x885 because it was checking for legacy/deprecatedmemory limites, the drm fb helpers are limited to the initial resolutionset on fb due to first problem (drm fb helpers being unable to handlehotplug crtc preferred mode changes).This also removes the kernel config for disabling fb support which hasn'tbeen used or supported in a very long time.Signed-off-by: Zack Rusin Reviewed-by: Maaz Mombasawala Reviewed-by: Martin Krastev Reviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20221022040236.616490-14-zack@kde.org List of files: /linux-6.15/drivers/gpu/drm/vmwgfx/Makefile

8afa13a0 - drm/vmwgfx: Implement DRIVER_GEM

Mon, 06 Dec 2021 17:26:12 +0000

drm/vmwgfx: Implement DRIVER_GEMThis is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfxwas written before GEM and has always used TTM. Over the years theTTM buffers started inherting from GEM objects but vmwgfx neverimplemented GEM making it quite awkward. We were directly settingvariables in GEM objects to not make DRM crash.This change brings vmwgfx inline with other DRM drivers and allows usto use a lot of DRM helpers which have depended on drivers with GEMsupport.Due to historical reasons vmwgfx splits the idea of a buffer and surfacewhich makes it a littly tricky since either one can be used in mostof our ioctl's which take user space handles. For now our BO's areGEM objects and our surfaces are opaque objects which are backed byGEM objects. In the future I'd like to combine those into a singleBO but we don't want to break any of our existing ioctl's so it willtake time to do it in a non-destructive way.Signed-off-by: Zack Rusin Reviewed-by: Martin Krastev Link: https://patchwork.freedesktop.org/patch/msgid/20211206172620.3139754-5-zack@kde.org List of files: /linux-6.15/drivers/gpu/drm/vmwgfx/Makefile

8aadeb8a - drm/vmwgfx: Remove the dedicated memory accounting

Mon, 06 Dec 2021 17:26:09 +0000

drm/vmwgfx: Remove the dedicated memory accountingvmwgfx shared very elaborate memory accounting with ttm. It was movedfrom ttm to vmwgfx in changef07069da6b4c ("drm/ttm: move memory accounting into vmwgfx v4")but because of complexity it was hard to maintain. Some parts of the codeweren't freeing memory correctly and some were missing accounting alltogether. While those would be fairly easy to fix the fundamental reasonfor memory accounting in the driver was the ability to invoke shrinkerwhich is part of TTM code as well (with support for unified memoryhopefully coming soon).That meant that vmwgfx had a lot of code that was either unused orduplicating code from TTM. Removing this code also prevents excessivecalls to global swapout which were common during memory pressurebecause both vmwgfx and TTM would invoke the shrinker when memoryusage reached half of RAM.Fixes: f07069da6b4c ("drm/ttm: move memory accounting into vmwgfx v4")Signed-off-by: Zack Rusin Reviewed-by: Martin Krastev Link: https://patchwork.freedesktop.org/patch/msgid/20211206172620.3139754-2-zack@kde.org List of files: /linux-6.15/drivers/gpu/drm/vmwgfx/Makefile

f6be2326 - drm/vmwgfx: Introduce a new placement for MOB page tables

Fri, 05 Nov 2021 19:38:45 +0000

drm/vmwgfx: Introduce a new placement for MOB page tablesFor larger (bigger than a page) and noncontiguous mobs we haveto create page tables that allow the host to find the memory.Those page tables just used regular system memory. Unfortunatelyin TTM those BO's are not allowed to be busy thus can't befenced and we have to fence those bo's because we don't wantto destroy the page tables while the host is still executingthe command buffers which might be accessing them.To solve it we introduce a new placement VMW_PL_SYSTEM whichis very similar to TTM_PL_SYSTEM except that it allowsfencing. This fixes kernel oops'es during unloading of the driver(and pci hot remove/add) which were caused by busy BO's inTTM_PL_SYSTEM being present in the delayed deletion list inTTM (TTM_PL_SYSTEM manager is destroyed before the delayeddeletions are executed)Signed-off-by: Zack Rusin Reviewed-by: Martin Krastev Cc: Christian König Cc: Thomas Hellström Link: https://patchwork.freedesktop.org/patch/msgid/20211105193845.258816-5-zackr@vmware.com List of files: /linux-6.15/drivers/gpu/drm/vmwgfx/Makefile
