Dave Airlie eac498baea addmap-base-2 patch from Jon Smirl:
sets up the DRM to have the ability to have permanent maps while the driver
    is loaded...
2004-08-24 10:43:45 +00:00
Erdi Chen 25e319c1ef This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:
DRM_IOCTL_VIA_DMA_INIT DRM_IOCTL_VIA_CMDBUFFER DRM_IOCTL_VIA_FLUSH
The first ioctl sets up an area in AGP memory that will be used as the ring
    buffer. The second ioctl copies a command buffer from user space memory
    to the ring buffer. The third ioctl waits for engine idle until it
    returns.
The motivation for this patch is to avoid the wait for engine idle call
    before each buffer flush in the current DRI driver. With this patch,
    the DRI driver can continue to flush its buffer as long as there is
    free space in the ring buffer.
This patch adds an additional copy operation on the command buffer. This
    buffer copying is necessary to support multiple DRI clients rendering
    simultaneously. Otherwise, more CPU time will be spent in the busy loop
    waiting for engine idle between DRI context switch. Even in the single
    client case, the tradeoff is reasonable in comparision to the kernel
    call to check for free buffer space for the client to render directly
    to the ring buffer.

Keith Whitwell 82157579b5 drm_ctx_dtor.patch Submitted by: Erdi Chen 2004-02-20 22:55:12 +00:00
Eric Anholt 66c9e3053f - Tie the DRM to a specific device: setunique no longer succeeds when given
a busid that doesn't correspond to the device the DRM is attached to.
    This is a breaking of backwards-compatibility only for the
    multiple-DRI-head case with X Servers that don't use interface 1.1.
- Move irq_busid to drm_irq.h and make it only return the IRQ for the
    current device. Retains compatibility with previous X Servers, cleans
    up unnecessary code. This means no irq_busid on !__HAVE_IRQ, but can be
    changed if necessary.
- Bump interface version to 1.2. This version when set signifies that the
    control ioctl should ignore the irq number passed in and enable the
    interrupt handler for the attached device. Otherwise it errors out when
    the passed-in irq is not equal to the device's.
- Store the highest version the interface has been set to in the device.
- Fix a recursion on DRM_LOCK in irq_uninstall on FreeBSD. This leaves
    irq_uninstall being done without the lock in some cases, but it was
    racey anyways.

Michel Daenzer 2655ccddf4 Memory layout transition:
the 2D driver initializes MC_FB_LOCATION and related registers sanely
the DRM deduces the layout from these registers
clients use the new SETPARAM ioctl to tell the DRM where they think the
    framebuffer is located in the card's address space
the DRM uses all this information to check client state and fix it up if
    necessary
This is a prerequisite for things like direct rendering with IGP chips and
    video capturing.

Eric Anholt b79d1b341f Move to "old-style" probing as documented in linux/Documentation/pci.txt.
This should resolve the probe problems with radeon framebuffer due to
    pci_driver attachment being exclusive.

Eric Anholt 06cb132e86 - Introduce a new ioctl, DRM_IOCTL_SET_VERSION. This ioctl allows the
server or client to notify the DRM that it expects a certain version of
    the device dependent or device independent interface. If the major
    doesn't match or minor is too large, EINVAL is returned. A major of -1
    means that the requestor doesn't care about that portion of the
    interface. The ioctl returns the actual versions in the same struct.
- Introduce DRM DI interface version 1.1. If the server requests version
    1.1, then the DRM sets the unique itself according to the busid of the
    device it probed, which may then be accessed as normal using getunique.
- Request version 1.1 in libdrm's drmOpenByBusID, allowing the X Server to
    request based on a BusID. Introduce a wrapper for DRM_IOCTL_SET_VERSION
    and bump libdrm minor version.
- Pass the busid in DRIScreenInit if libdrm can handle both a busid and
    name. This allows drmOpenByBusID to be used to find the DRM instead of
    just the driver name, which allows us in the future to tie a DRM more
    strongly to the device it probed to. Introduce a function
    DRICreatePCIBusID which creates a busid in the form pci:oooo:bb:dd.f
    similar to linux's pci_name() function. This matches the format used by
    the DRM in version 1.1. libdrm knows how to match both this format and
    the old PCI🅱️d:f format.
- Use the new DRICreatePCIBusID function in the *_dri.c to request the new,
    more exact busid format.

Eric Anholt 2950f9e682 - Move IRQ functions from drm_dma.h to new drm_irq.h and disentangle them
from __HAVE_DMA. This will be useful for adding vblank sync support to
    sis and tdfx. Rename dma_service to irq_handler, which is more
    accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
    the right number of underscores. This may have been a problem in the
    case that the server died without doing its DRM_IOCTL_CONTROL to
    uninit.

Eric Anholt ff58476011 - Converted Linux drivers to initialize DRM instances based on PCI IDs, not
just a single instance. Moved the PCI ID lists from <card>_drv.c in BSD
    to <card>.h. The PCI ID lists include a driver private field, which may
    be used by drivers for chip family or other information. Based on work
    by jonsmirl.
- Make tdfx_drv.c and tdfx.h match other drivers.
- Fixed up linking of sis shared files.
Tested with Radeon and SiS on Linux and FreeBSD, including a Linux setup
    with
2 SiS cards in a machine, but only one head being used (with DRI)

David Dawes c2d7ff1bf9 Bring some drm module changes over from the XFree86 trunk:
- Reset 'bound' flag for an agp entry after undbind succeeded in
    drm_agpsupport.h (Egbert Eich).
- Ignore hw_lock for drm device if lock was set by a different instance (ie
    Xserver) to prevent second server from spinning in driver release
    function (currently only relevant for i8xx drm drivers) (David Dawes).
- Use the agpgart "key" for the unique handle for bindings rather than the
    memory address (the key is guaranteed to be unique) (David Dawes).
