drm/vmwgfx: Make all surfaces shareable

2024-01-30T19:18:18+00:00

There is no real need to have a separate pool for shareable and non-shareable surfaces. Make all surfaces shareable, regardless of whether the drm_vmw_surface_flag_shareable has been specified.

drm/vmwgfx: Allow querying of the SVGA PCI id from the userspace

2022-03-11T18:29:35+00:00

Mesa3D loaders require knowledge of the devices PCI id. SVGAv2 and v3 have different PCI id's, but the same driver is used to handle them both. To allow Mesa3D svga driver to be loaded automatically for both SVGAv2 and SVGAv3 make the kernel return the PCI id of the currently running device.

drm/vmwgfx: Allow checking for gl43 contexts

2021-12-09T18:16:29+00:00

To make sure we're running on top of hardware that can support GL4.3 we need to add a way of querying for those capabilities. DRM_VMW_PARAM_GL43 allows userspace to check for presence of GL4.3 capable contexts.

drm/vmwgfx: Introduce VMware mks-guest-stats

2021-06-12T04:00:53+00:00

VMware mks-guest-stats mechanism allows the collection of performance stats from guest userland GL contexts, as well as from vmwgfx kernelspace, via a set of sw- defined performance counters. The userspace performance counters are (de)registerd with vmware-vmx-stats hypervisor via new iocts. The vmwgfx kernelspace counters are controlled at build-time via a new config DRM_VMWGFX_MKSSTATS. * Add vmw_mksstat_{add|remove|reset}_ioctl controlling the tracking of mks-guest-stats in guest winsys contexts * Add DRM_VMWGFX_MKSSTATS config to drivers/gpu/drm/vmwgfx/Kconfig controlling the instrumentation of vmwgfx for kernelspace mks-guest-stats counters * Instrument vmwgfx vmw_execbuf_ioctl to collect mks-guest-stats according to DRM_VMWGFX_MKSSTATS Signed-off-by: Martin Krastev Reviewed-by: Zack Rusin Signed-off-by: Zack Rusin Link: https://patchwork.freedesktop.org/patch/msgid/20210609172307.131929-3-zackr@vmware.com

drm/vmwgfx: Add surface define v4 command

2020-03-23T21:48:57+00:00

Surface define v4 added new member buffer_byte_stride. With this patch add buffer_byte_stride in surface metadata and create surface using new command if support is available. Also with this patch replace device specific data types with kernel types.

drm/vmwgfx: add ioctl for messaging from/to guest userspace to/from host

2020-01-15T10:54:16+00:00

Up to now, guest userspace does logging directly to host using essentially the same rather complex port assembly stuff as the kernel. We'd rather use the same mechanism than duplicate it (it may also change in the future), hence add a new ioctl for relaying guest/host messaging (logging is just one application of it).

drm/vmwgfx: Add surface dirty-tracking callbacks

2019-11-06T14:45:32+00:00

Add the callbacks necessary to implement emulated coherent memory for surfaces. Add a flag to the gb_surface_create ioctl to indicate that surface memory should be coherent. Also bump the drm minor version to signal the availability of coherent surfaces.
