2005-04-20A fix for a locking bug which is triggered when a client tries to lock withThomas Hellstrom
flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock.

2004-08-24addmap-base-2 patch from Jon Smirl:Dave Airlie
sets up the DRM to have the ability to have permanent maps while the driver is loaded...
2004-08-24This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:Erdi Chen
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.

2004-02-20drm_ctx_dtor.patch Submitted by: Erdi ChenKeith Whitwell
2003-11-05- Tie the DRM to a specific device: setunique no longer succeeds when givenEric Anholt
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.
2003-11-04Memory layout transition:Michel Daenzer
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.
2003-10-24Switch pci enumeration call to work on both 2.4 and 2.6 pci_for_each_dev isJon Smirl
not supported on 2.6
2003-10-23Move to "old-style" probing as documented in linux/Documentation/pci.txt.Eric Anholt
This should resolve the probe problems with radeon framebuffer due to pci_driver attachment being exclusive.
2003-10-23- Introduce a new ioctl, DRM_IOCTL_SET_VERSION. This ioctl allows theEric Anholt
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:b:d:f format. - Use the new DRICreatePCIBusID function in the *_dri.c to request the new, more exact busid format.
2003-10-19Fix probing on 2.5+ kernels, which require that drivers have .id_table set.Eric Anholt
We use PCI_ANY_ID to ask that our probe is called for every available device. Submitted by: jonsmirl
2003-10-17- Move IRQ functions from drm_dma.h to new drm_irq.h and disentangle themEric Anholt
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.
