2009-01-07drm: fix ordering of driver unload vs agp unload.Dave Airlie
For KMS drivers, we really need to cleanup the driver before disabling the AGP subsystem. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-01-07drm/i915: Don't allow objects to get bound while VT switched.Eric Anholt
This avoids a BUG_ON in the enter_vt path due to objects being in the GTT when we shouldn't have ever let them be (as we're not supposed to touch the device during that time). This was triggered by a change in the 2D driver to use the GTT mapping of objects after pinning them to improve software fallback performance.

2009-01-06Check fops_get() return valueLaurent Pinchart
Several subsystem open handlers dereference the fops_get() return value without checking it for nullness. This opens a race condition between the open handler and module unloading. A module can be marked as being unloaded (MODULE_STATE_GOING) before its exit function is called and gets the chance to unregister the driver. During that window open handlers can still be called, and fops_get() will fail in try_module_get() and return a NULL pointer. This change checks the fops_get() return value and returns -ENODEV if NULL.

2008-12-29DRM: i915: add mode setting supportJesse Barnes
This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.

2008-12-29DRM: add mode setting supportDave Airlie
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.

2008-12-29drm: fix leak of uninitialized data to userspaceVegard Nossum
...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.

2008-12-29drm: move to kref per-master structures.Dave Airlie
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: Dave Airlie <airlied@redhat.com>

2008-12-19drm/i915: GEM on PAE has problems - disable it for now.Dave Airlie
On PAE systems, GEM allocates pages using shmem, and passes these pages to be bound into AGP, however the AGP interfaces + the x86 set_memory interfaces all take unsigned long not dma_addr_t.

Since applying the fix suggested by the errata (disabling MSI), we've had issues with interrupts being stuck on despite IIR being 0 on GM965 hardware. Most reporters of the issue have confirmed that turning MSI back on fixes things, and given the difficulties experienced in getting reliable MSI working on Linux, it's believable that the errata was about software issues and not actual hardware issues.
