Need to overhaul the mess that is driver ioctls
|
|
believing userspace causes oopses
|
|
This reverts commit 6671ad1917698b6174a1af314b63b3800d75248c.
The vblank ioctl needs to update the userspace parameters when interrupted by
a signal, which was prevented by this. Let's see if this breaks other ioctls...

taken from modesetting branch but could be useful outside it.

Rip out the whole head thing and replace it with an idr and drm_minor
structure.

Merge in the latest master bits and update the remaining drivers (except
mach64 which math_b is working on). Also remove the 9xx hack from the i915
driver; it seems to be correct.

Make DRM devices use real Linux devices instead of class devices, which are
going away. While we're at it, clean up some of the interfaces to take
struct drm_device * or struct device * and use the global drm_class where
needed instead of passing it around.
|
|
Set bo init minor to 0.
Add the version function to header.
|
|
Implement a version check IOCTL for drivers that don't use
drmMMInit from user-space.
Remove the minor check from the kernel code. That's really up
to the driver.
Bump major.
|
|
Remove need for lock for now.
May create races when we clean memory areas or on takedown.
Needs to be fixed.
Really do a validate on buffer creation in order to avoid problems with
fixed memory buffers.

set pinning."

We now always create a drm_ref_object for user objects and this is then the only
things that holds a reference to the user object. This way unreference on will
destroy the user object when the last drm_ref_object goes way.

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.

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.

ioctl wrapper
|
|
|
|
- move pre/post modeset ioctl to core
- fixup i915 buffer swap
- fix outstanding signal count code
- create new core vblank init routine
- test (works with glxgears)
- simplify i915 interrupt handler

This reverts commit 6e860d08d0f5b1e9a2d711aaf9fd6b982aa8039e.
As I said not a good plan - this macro will have to stay for now,
trying to do the vbl code with the inline was a bit messy - may need specialised
drm wait on functions
|
|
This cleans this code up a lot and uses the generic Linux idr which is
designed for this.

This is the first bunch of ioctls

This makes the drms use of the list handling macros a lot cleaner
and more along the lines of how they should be used.

retain the op operation for validate/fence operations
