bjorn3 d528fb73b4 drivers: Use map_bar instead of physmap where possible 
Physmap requires root, while map_bar in the future could be run as
unprivileged process given a pcid handle for the target device.

bjorn3 018d795eb0 drivers/graphics: Avoid unnecessary force probes 
Force probes can be rather expensive on real hardware so according to
the drm_mode_get_connector docs it should only be done at startup, on a
hotplug event and when explicitly requested by the user.

bjorn3 2436639271 drivers/graphics: Avoid duplicate get_connector calls 2026-05-09 12:07:58 +02:00
bjorn3 15c3327adb drivers/graphics/ihdgd: Remove unnecessary reset call 
alloc_buffers already starts as empty.

bjorn3 1dcf00dc8e drivers/graphics/driver-graphics: Replace hw_cursor_size with has_cursor_plane 
Clients get the cursor size using get_cap. hw_cursor_size is only used
to determine the existence of a cursor plane nowadays.

bjorn3 8fdd5f3998 drivers/graphics/ihdgd: Replace DeviceFb with GpuBuffer for dumb buffers 
Dumb buffers only have a size like GpuBuffer, not width, height and
stride like DeviceFb.

bjorn3 6311833765 drivers/graphics/bgad: Remove bgad 
The only thing it does it changing the size of the region that the
graphics adapter sees as framebuffer. It doesn't actually tell vesad to
resize the framebuffer nor does it implement an actual full graphics
driver. For basic usage the bootloader setup framebuffer is sufficient
and for anything more advanced, virtio-gpu is a much better option that
we already have a full graphics driver for.
 2026-04-14 21:18:43 +02:00
bjorn3 317a0178b6 Introduce scheme-utils crate and HandleMap type 
HandleMap deduplicates the id assignment for handles and unlike most
existing implementations handles overflow just fine.

bjorn3 bf5286d25d drivers/graphics: Replace CpuBackedBuffer::sync_range with CpuBackedBuffer::sync_rect 
This can be a bit more efficient by doing bounds checks before the main
loop.

bjorn3 6473d987c3 drivers/graphics/ihdgd: List correct pipes for Alchemist 2026-03-28 00:02:38 +01:00
bjorn3 f152bbad23 drivers/graphics/ihdgd: Implement support for mapping memory to the GPU 
This is done by adding entries to the global GTT page table. At startup
it only contains entries for a small chunk of memory reserved for the
GPU. This small chunk is rarely enough to contain all framebuffers we
need to allocate.
 2026-03-27 22:45:26 +01:00
bjorn3 70bba179c4 drivers/graphics/ihdgd: Introduce GpuBuffer 
Unlike DeviceFb a GpuBuffer only has a size, not a width, height and
stride. In the future GpuBuffer can be used for dumb buffers as well as
any other kind of memory we may need to allocate on the gpu.

bjorn3 8ae815aca7 drivers/graphics: Replace width and height methods on Buffer with size 
A buffer is not necessarily a framebuffer. It may also be a blob of
bytes.

bjorn3 fcee1d7d86 drivers/graphics/ihdgd: Measure fb stride in bytes rather than pixels 
This is how stride is generally stored.

bjorn3 7177fe0a86 drivers/graphics: Implement shadow buffer for dumb buffers 
This is necessary to get even remotely acceptable performance when dumb
buffers are backed by write-combining memory.

bjorn3 d08300c8b5 drivers/graphics: Make objects generic over GraphicsAdapter rather than specific driver data 2026-03-20 23:19:50 +01:00
bjorn3 5e7fc9d71a drivers/graphics: Remove refcounting for all KmsObject's 
Doing the refcounting outside the enum doesn't allow refcounting a
downcasted object. And most objects don't need refcounting after all.

bjorn3 5b88dadc4f drivers/graphics: Move connector<->crtc binding to KmsConnector 
A connector can only get input from one CRTC and the CRTC_ID property is
on the connector. There is no CONNECTOR_IDS property on CRTCs.
