We can, by virtue of a vblank interrupt firing in the middle of setting up the unpin work (i.e. after we set the unpin_work field and before we write to the ringbuffer) enter intel_finish_page_flip() prior to receiving the pending flip notification. Therefore we can expect to hit intel_finish_page_flip() under normal circumstances without a pending flip and even without installing the pending_flip_obj. This is exacerbated by aperture thrashing whilst binding the framebuffer References: Bug 28079 - "glresize" causes kernel panic in intel_finish_page_flip. https://bugs.freedesktop.org/show_bug.cgi?id=28079Reported-by:

References: Bug 15733 - Crash when accessing nonexistent GTT entries in i915 https://bugzilla.kernel.org/show_bug.cgi?id=15733 On G33 and above, the size of the GTT space is determined by the GMCH control register. Prior to this revision, the size is determined by the size of the aperture. So we must careful to map and fill the appropriate range depending on chipset. Signed-off-by:

Add power monitoring support to the i915 driver for use by the IPS driver. Export the available power info to the IPS driver through a few new inter-driver hooks. When used together, the IPS driver and this patch can significantly increase graphics performance on Ironlake class chips. Signed-off-by:

This doesn't change the clock limits (minimums), i.e. it won't make it output 720x576 PAL nor 720x480 NTSC, but it will work with modes like 1080i etc. (including GLX and textured Xvideo, not sure about the overlay). Tested on i915 + analog VGA, it would be worth checking if newer chips (and which ones) still support interlaced mode. Signed-off-by:

The BSD (bit stream decoder) ring is used for accessing the BSD engine which decodes video bitstream for H.264 and VC1 on G45+. It is asynchronous with the render ring and has access to separate parts of the GPU from it, though the render cache is coherent between the two. Signed-off-by:

The active list and request list move into the ringbuffer structure, so each can track its active objects in the order they are in that ring. The flushing list does not, as it doesn't matter which ring caused data to end up in the render cache. Objects gain a pointer to the ring they are active on (if any). Signed-off-by:

With the advent of the BSD ring, be clear about which ring this is. The docs are pretty consistent with calling this the Render engine at this point.

This is preparation for supporting multiple ringbuffers on Ironlake. The non-copy-and-paste changes are: - de-staticing functions - I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files. - i915_gem_add_request had only half its implementation copy-and-pasted out of the middle of it.

The i915's implementation of KMS requires GEM in order to manage the memory and execution domains of the framebuffer and associated resources. By the point at which we detect broken a BIOS and need to disable GEM, we have already registered ourselves as a KMS driver with several subsystems. Rather than introducing a fragile unwind and attempt to continue with UMS, spit out an error and unload the driver.

This reverts commit 480b02df, since Rafael reports that it causes occasional kernel paging request faults in load_module(). Dropping the module lock and re-taking it deep in the call-chain is definitely not the right thing to do. That just turns the mutex from a lock into a "random non-locking data structure" that doesn't actually protect what it's supposed to protect. Requested-and-tested-by:

This adds: alias: devname:<name> to some common kernel modules, which will allow the on-demand loading of the kernel module when the device node is accessed. Ideally all these modules would be compiled-in, but distros seems too much in love with their modularization that we need to cover the common cases with this new facility. It will allow us to remove a bunch of pretty useless init scripts and modprobes from init scripts. The static device node aliases will be carried in the module itself. The program depmod will extract this information to a file in the module directory: $ cat /lib/modules/2.6.34-00650-g537b60d1-dirty/modules.devname # Device nodes to trigger on-demand module loading. microcode cpu/microcode c10:184 fuse fuse c10:229 ppp_generic ppp c108:0 tun net/tun c10:200 dm_mod mapper/control c10:235 Udev will pick up the depmod created file on startup and create all the static device nodes which the kernel modules specify, so that these modules get automatically loaded when the device node is accessed: $ /sbin/udevd --debug ... static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184 static_dev_create_from_modules: mknod '/dev/fuse' c10:229 static_dev_create_from_modules: mknod '/dev/ppp' c108:0 static_dev_create_from_modules: mknod '/dev/net/tun' c10:200 static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235 udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666 udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666 A few device nodes are switched to statically allocated numbers, to allow the static nodes to work. This might also useful for systems which still run a plain static /dev, which is completely unsafe to use with any dynamic minor numbers. Note: The devname aliases must be limited to the *common* and *single*instance* device nodes, like the misc devices, and never be used for conceptually limited systems like the loop devices, which should rather get fixed properly and get a control node for losetup to talk to, instead of creating a random number of device nodes in advance, regardless if they are ever used. This facility is to hide the mess distros are creating with too modualized kernels, and just to hide that these modules are not compiled-in, and not to paper-over broken concepts.
