Re-implement the power management.
...
There's two choices when fb is or isn't loaded as we treat ourselves as a
PCI driver in the latter case.
If we are a PCI driver, then register the suspend/resume functions
directly. If not, then we register as a sysdev and pick up the
suspend/resume actions and pump them down into a generic *power
function.
It'll be nice when this little mess is sorted out with regard to being a
real PCI driver ;-/

that a device absolutely is, absolutely is not, or may or may not be
AGP. Modify the i915 DRM to use this to force all i9x5 devices to be
"AGP" (even the PCI-e devices).

Change the MGA initialization and cleanup a bit. The dev_private structure
...
is now allocated (and partially filled in) by the new
mga_driver_preinit function.
This allows the driver to detect the type of card (i.e., G200 class vs.
G400 class) on its own. The chipset value passed to mga_dma_init is now
ignored. This same technique is used by the radeon DRM.
As a result of this, mga_driver_pretakedown was converted to
mga_driver_postcleanup. This routine gets called in some other places
than might be expected, and it sets the dev_private pointer to NULL.
That little gem took over an hour to track down. :(

Added device_is_agp callback to drm_driver. This function is called by the
...
platform-specific drm_device_is_agp function. Added implementation of
this function the the Linux-specific portion of the MGA driver to
detect PCI G450 cards. Added code to the Linux-specific portion of the
generic DRM layer to not initialize AGP infrastructure if the card is
not AGP (this matches what already existed in BSD).
Bumped the driver date and the driver patch-level for MGA.
This mostly fixes bugzilla #3248 . The BSD side still needs an
implementation of mga_driver_device_is_agp.

Convert BSD code to mostly use bus_dma, the dma abstraction for dealing
...
with IOMMUs and such. There is one usage of the forbidden vtophys()
left in drm_scatter.c which will be fixed up soon. This required a KPI
change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
keeps track of os-specific bits, rather than just passing around the
vaddr/busaddr/size.

A fix for a locking bug which is triggered when a client tries to lock with

flag DMA_QUIESCENT (typically the X server), but gets interrupted by a

DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it

possibly DMA_READY without having the lock.

2005-03-08 23:47:11 +00:00
81459d6e50
Close a race which could allow for privilege escalation by users with DRI
...
privileges on Radeon hardware. Essentially, a malicious program could
submit a packet containing an offset (possibly in main memory) to be
rendered from/to, while a separate thread switched that offset in
userspace rapidly between a valid value and an invalid one.
radeon_check_and_fixup_offset() would pull the offset in from user
space, check it, and spit it back out to user space to be copied in
later by the emit code. It would sometimes catch the bad value, but
sometimes the malicious program could modify it after the check and get
an invalid offset rendered from/to.
Fix this by allocating a temporary buffer and copying the data in at once.
While here, make the cliprects stuff not do the VERIFYAREA_READ and
COPY_FROM_USER_UNCHECKED gymnastics, avoiding a lock order reversal on
FreeBSD. Performance impact is negligible -- no difference on r200 to
~1% improvement on rv200 in quake3 tests (P4 1Ghz, demofour at
1024x768, n=4 or 5).

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.

Add a hotplug event to DRM. Parameters match the ones from the general PCI

hotplug event plus the addition of one requesting RESET. Put your

to stop you from resetting your boot display.
