This is done by 1) Wake up lock waiters when we close the master file descriptor. Not when the master structure is removed, since the latter requires the waiters themselves to release the refcount on the master structure -> Deadlock. 2) Send a SIGTERM to all clients waiting for the lock. Normally these clients will get a SIGPIPE when the X server dies, but clients may also spin trying to grab the DRM lock, without getting any sort of notification.

Add mode setting support to the DRM layer. This is a fairly big chunk of work that allows DRM drivers to provide full output control and configuration capabilities to userspace. It was motivated by several factors: - the fb layer's APIs aren't suited for anything but simple configurations - coordination between the fb layer, DRM layer, and various userspace drivers is poor to non-existent (radeonfb excepted) - user level mode setting drivers makes displaying panic & oops messages more difficult - suspend/resume of graphics state is possible in many more configurations with kernel level support This commit just adds the core DRM part of the mode setting APIs. Driver specific commits using these new structure and APIs will follow.

...so drm_getunique() is trying to copy some uninitialized data to userspace. The ECX register contains the number of words that are left to copy -- so there are 5 * 4 = 20 bytes left. The offset of the first uninitialized byte (counting from the start of the string) is also 20 (i.e. 0xf65d2294&((1 << 5)-1) == 20). So somebody tried to copy 40 bytes when the string was only 19 long. In drm_set_busid() we have this code: dev->unique_len = 40; dev->unique = drm_alloc(dev->unique_len + 1, DRM_MEM_DRIVER); ... len = snprintf(dev->unique, dev->unique_len, pci:%04x:%02x:%02x.%d", ...so it seems that dev->unique is never updated to reflect the actual length of the string. The remaining bytes (20 in this case) are random uninitialized bytes that are copied into userspace. This patch fixes the problem by setting dev->unique_len after the snprintf(). airlied- I've had to fix this up to store the alloced size so we have it for drm_free later.

This is step one towards having multiple masters sharing a drm device in order to get fast-user-switching to work. It splits out the information associated with the drm master into a separate kref counted structure, and allocates this when a master opens the device node. It also allows the current master to abdicate (say while VT switched), and a new master to take over the hardware. It moves the Intel and radeon drivers to using the sarea from within the new master structures. Signed-off-by: NDave Airlie <airlied@redhat.com>

GEM allows the creation of persistent buffer objects accessible by the graphics device through new ioctls for managing execution of commands on the device. The userland API is almost entirely driver-specific to ensure that any driver building on this model can easily map the interface to individual driver requirements. GEM is used by the 2d driver for managing its internal state allocations and will be used for pixmap storage to reduce memory consumption and enable zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: NDave Airlie <airlied@redhat.com>

Bugzilla Bug #9457 Add refcounting of user waiters to the DRM hardware lock, so that we can use DRM_LOCK_CONT flag more conservatively. Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager Signed-off-by: NDave Airlie <airlied@linux.ie>

Keep hashed user tokens, with the following changes: 32-bit physical device addresses are mapped directly to user-tokens. No duplicate maps are allowed, and the addresses are assumed to be outside of the range 0x10000000 through 0x30000000. The user-token is identical to the 32-bit physical start-address of the map. 64-bit physical device addressed are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. Other map types, like upcoming TTM maps are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. Implement hashed map lookups. Signed-off-by: NDave Airlie <airlied@linux.ie>

Rename the driver hooks in the DRM to something a little more understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating.

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). Fix up i810/i830 and i915 drivers to always return AGP as they don't always report the capability. Fix the MGA to not report AGP for a card that has an AGP chip behind a PCI bridge.
