I'm not entirely sure this is required and it won't work with the dpm restructing anyway. Signed-off-by:Alex Deucher <alexander.deucher@amd.com>

This is just used for a debugfs file, and we can easily reconstruct this number by just walking the list twice. Which isn't really bad for a debugfs file anyway. So let's rip this out. There's the other issue that the dev->vmalist itself is a bit useless, since that can be reconstructed with all the memory mapping information from proc. But remove that is a different topic entirely. Signed-off-by:

It's racy, and it's only used in debugfs. There are simpler ways to know whether something is going on (like looking at dmesg with full debugging enabled). And they're all much more useful. So let's just rip this out. Signed-off-by:

Now dev->ioctl_count tries to prevent the device from disappearing if it's still in use. And if we'd actually need this code it would be hopelessly racy and broken. But luckily the vfs already takes care of this. So we can just rip it out. Signed-off-by:

David Herrmann dutifully moved this locking along when moving the agp_init call out of the generic drm_dev_register into the pci specific load helpers. But afaict there's no need and the reason for that locking has been purely a historical accident - we need the lock around the driver dev node registration to paper over the midlayer init races, and the agp init simply ended up in there. The real fix for all this is of course to delay the dev (and sysfs/debugfs) interface registration until everything is fully set up. Until then stop the cargo-cult locking from spreading and remove the locking. Cc: David Herrmann <dh.herrmann@gmail.com> Signed-off-by:

Call drm_pci_agp_destroy directly, there's no point in the indirection. Long term we want to shuffle this into each driver's unload logic, but that needs cleared-up drm lifetime rules first. v2: Add a dummy function for !CONFIG_PCI, spotted my David Herrmann. v3: Fixup for the coding style police.

Wrapping a kfree is pointless. v2: Add a comment to the kerneldoc for drm_agp_init to explain where the kfree happens as requested by David. Note that for modeset drivers agp cleanup is fairly complicated anyway: The drm_agp_clear is a noop and drivers must call drm_agp_release on their own. Which they all seem to do properly.

The PCI bus helper is the only user of it. Call it directly before device-registration to get rid of the callback. Note that all drm_agp_*() calls are locked with the drm-global-mutex so we need to explicitly lock it during initialization. It's not really clear why it's needed, but lets be safe. v2: Rebase on top of the agp_init interface change. v3: Remove the rebase-fail where I've accidentally killed the ->irq_by_busid callback a bit too early.

Most place actually want to just check for dev->agp (most do, but a few don't so this fixes a few potential NULL derefs). The only exception is the agp init code which should check for the AGP driver feature flag. Signed-off-by:

Only the two intel drivers need this and they can easily check for working agp support in their driver ->load callbacks. This is the only reason why agp initialization could fail, so allows us to rip out a bit of error handling code in the next patch. Signed-off-by:

In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Also remove the dev_err call to avoid redundant error message. Signed-off-by:

The current values seem to be defined in a format that's specific to the i915, gma500 and radeon drivers. To make this more generally useful, use the values as defined in the specification. While at it, prefix the constants with DP_ for improved namespacing. Signed-off-by:

Gone with the new gem vma offset manager from David. We can also ditch the uapi header definition from the enum since userspace never used this. It ended up in there purely for historical reasons (for reusing the old drm mmap code essentially), not because userspace ever needed it. Cc: David Herrmann <dh.herrmann@gmail.com> Reviewed-by:

There's really no need for the drm core to keep a list of all devices of a given driver - the linux device model keeps perfect track of this already for us. The exception is old legacy ums drivers using pci shadow attaching. So rename the lists to make the use case clearer and rip out everything else. v2: Rebase on top of David Herrmann's drm device register changes. Also drop the bogus dev_set_drvdata for platform drivers that somehow crept into the original version - drivers really should be in full control of that field. v3: Initialize driver->legacy_dev_list outside of the loop, spotted by David Herrmann. v4: Rebase on top of the newly created host1x drm_bus for tegra.
