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.
2003-10-23- 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.
2003-10-03Stylistic preparation for SMPng locking work: DRM_LOCK/DRM_UNLOCK have sideEric Anholt
effects, so make them look like functions (add parenthesis).
2003-10-02Mostly whitespace cleanups and style(9) fixes focused on "if(" -> "if ("Eric Anholt
Change some nearby memset()s to bzero()s or to calloc allocations to take advantage of M_ZERO). Reverse some error tests to reduce high levels of indentation. Move the sg_cleanup() call out of the maplist loop in DRM(takedown)-- I can't see any need for it to be inside.
2003-08-19- Remove $FreeBSD$ tags as they weren't too useful and merges are now beingEric Anholt
done through perforce. - Add copyright headers to drm_os_*bsd.h, still need to research the other copyright-less files better.
2003-04-25Merge from FreeBSD-current.Eric Anholt
2003-04-24Remove more gamma DMA infrastructure. Most of this code was copied straightEric Anholt
from linux, so it could be added back if some driver needed it in the future.
2003-04-24Remove more gamma DMA code. This isn't all of it, but it's a major portion.Eric Anholt
2003-04-24Remove a bunch of dead code and fix spelling of a couple of comments.Eric Anholt
2003-03-11Merge back from FreeBSD-current, adding FreeBSD ID tags to aid futureEric Anholt
merging. Also includes an update to radeon PCI IDs.
