This should let us allocate buffers without holding the hardware lock.
While here, add DRM_DEBUG info for the drm_bo ioctls, so you can see something
more specific than just the cmd value per ioctl.
|
|
This cleans up the create/validate interfaces for this very uncommon path, and
makes pinned object creation much easier to use for the X Server.

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.

Fixes the getclient test and dritest -c.

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.

For reasons that I don't understand, the drm_addmap call would succeed
in xgi_driver_load, but writes to the map later would oops. Moving it
to xgi_bootstrap fixes this problem.

With this, all modules build again.

This might break something, stdint.h inclusion in drm.h maybe required
but I'm not sure yet what platforms have it what ones don't.

The ioctlss XGI_ESC_DEVICE_INFO, XGI_ESC_MEM_COLLECT,
XGI_ESC_PCIE_CHECK, XGI_ESC_GET_SCREEN_INFO, XGI_ESC_PUT_SCREEN_INFO,
XGI_ESC_MMIO_INFO, and XGI_ESC_SAREA_INFO, are completely unnecessary.
The will be doubly useless when the driver is converted to the DRM
infrastructure.

Actually a NV04-NV50 ttm backend for both PCI and PCIEGART, but PCIGART
support for G8X using the current mm has been hacked on top of it.
