* drm/cirrus: rewrite and modernize driver.Gerd Hoffmann2019-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Time to kill some bad sample code people are copying from ;) This is a complete rewrite of the cirrus driver. The cirrus_mode_set() function is pretty much the only function which is carried over largely unmodified. Everything else is upside down. It is a single monster patch. But given that it does some pretty fundamental changes to the drivers workflow and also reduces the code size by roughly 70% I think it'll still be alot easier to review than a longish baby-step patch series. Changes summary: - Given the small amout of video memory (4 MB) the cirrus device has the rewritten driver doesn't try to manage buffers there. Instead it will blit (memcpy) the active framebuffer to video memory. - All gem objects are stored in main memory and are manged using the new shmem helpers. ttm is out. - It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24 or RG16 at blit time if needed, to avoid the pitch becoming larger than what the cirrus hardware can handle. - The simple display pipeline is used. - The generic fbdev emulation is used. - It's a atomic driver now. - It runs wayland.

| * drm: flip cirrus driver status to "obsolete".Gerd Hoffmann2017-01-101-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also update Kconfig help text, explaining things: Cirrus is obsolete, the hardware was designed in the 90ies and can't keep up with todays needs. More background: https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/ Better alternatives are: - stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+) - qxl (DRM_QXL, qemu -vga qxl, works best with spice) - virtio (VIRTIO_GPU), qemu -vga virtio) Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* drm/cirrus: make fbdev support really optionalTobias Jakobi2016-07-181-4/+0
| | | | | | | | | | Currently enabling QEMU Cirrus DRM support automatically pulls in fbdev dependency. However this dep is unnecessary since DRM core already handles this for us (DRM_FBDEV_EMULATION).

* drm: Add separate Kconfig option for fbdev helpersDaniel Vetter2013-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

* drm/kms: driver for virtual cirrus under qemuDave Airlie2012-05-171-0/+11
This is the initial driver for emulated cirrus GPU found in qemu. This driver only supports the emulated GPU and doesn't attempt to bind to any real cirrus GPUs. This driver is intended to be used with xf86-video-modesetting in userspace. It requires at least version 0.3.0 This follow the same design as ast and mgag200, and is based on work done by Matthew Garrett previously. This GPU has no hw cursor, and it can't scanout 32-bpp, only packed 24-bpp. i.e. it sucks. Reviewed-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
