1. DRM_NOUVEAU_GPUOBJ_FREE
Used to free GPU objects. The obvious usage case is for Gr objects,
but notifiers can also be destroyed in the same way.
GPU objects gain a destructor method and private data fields with
this change, so other specialised cases (like notifiers) can be
implemented on top of gpuobjs.
2. DRM_NOUVEAU_CHANNEL_FREE
3. DRM_NOUVEAU_CARD_INIT
Ideally we'd do init during module load, but this isn't currently
possible. Doing init during firstopen() is bad as X has a love of
opening/closing the DRM many times during startup. Once the
modesetting-101 branch is merged this can go away.
IRQs are enabled in nouveau_card_init() now, rather than having the
X server call drmCtlInstHandler(). We'll need this for when we give
the kernel module its own channel.
4. DRM_NOUVEAU_GETPARAM
Add CHIPSET_ID value, which will return the chipset id derived
from NV_PMC_BOOT_0.
4. Use list_* in a few places, rather than home-brewed stuff.

This extra increase was causing fence leaks on my system, due to create/user add already increasing it twice no need for a 3rd go.

This code comes directly from the X server.

When the GE is shut down, an empty command packet without a begin-link
must be sent. After this command is sent, wait for the hardware to go
idle. Finally, turn off the GE and disable MMIO.

The wrong offset was being passed to xgi_find_pcie_virt. This would
cause an oops in addFlush2D.

The core DRM lastclose routine automatically destroys all mappings and
releases SG memory. XP10 DRM and DDX assumed this data stayed around
until module unload. xgi_bootstrap was reworked to recreate all these
mappings. In addition, the drm_addmap for the GART backing store was
moved into the kernel. This causes a change to the ioctl protocol and
a version bump.

Based on review comments from airlied, XGI_CHECK_PCI_CONFIG is
removed. He believes (and I tend to agree) that this is a largely
unnecessary workaround for a bug elsewhere.

This patch removes some obviously dead code spotted by the Coverity
checker.

There were numerous unnecessary fields in xgi_cmd_info. The remaining
fields had pretty crummy names. Cut out the cruft, and rename the
rest. As a result, the unused parameter "triggerCounter" to
triggerHWCommandList can be removed.

Debug print fix in drm_release().
Forgotten local variable init in drm_setversion().
Unnecessary put_user() in drm_addmap_ioctl().
ioctl->cmd check broken in drm_ioctl(); workaround.

The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures. This also means that XFree86 4.2.0 support for i810 DRM
is lost.

As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM. There is a 1:1 mapping, so this
should be a noop. This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.

This was used to make all ioctl handlers return -errno on linux and errno on
*BSD. Instead, just return -errno in shared code, and flip sign on return from
shared code to *BSD code.

Generate the begin command once in a temporary buffer. Then,
depending on whether the command is to be written directly to the
hardware or to a secondary buffer, copy to command to the correct place.
|
|
Moved the getCurBatchBeginPort before its only caller. Modified
function to return the command ID instead of the port offset.
Function also now assumes input begin type is value.
Added code to ioctl handler to validate begin type.

xgi_cmdlist_initialize wasn't correctly checking for errors from
xgi_pcie_alloc. Furthermore, xgi_bootstrap, the one caller of
xgi_cmdlist_initialize, wasn't check its return value.
