* drm/i915: fix modeset devname allocation + agp init return check.Dave Airlie2008-12-29
| | | | | | | | | | devname needs to be allocated before the irq is installed, so the irq routines get the correct name in /proc. Also check the return value from the AGP init function, and fixup the exit points. Signed-off-by: Dave Airlie <airlied@redhat.com>

* DRM: i915: add mode setting supportJesse Barnes2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* DRM: add mode setting supportDave Airlie2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm: fix leak of uninitialized data to userspaceVegard Nossum2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ...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.

* drm: move to kref per-master structures.Dave Airlie2008-12-29
| | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the tuner modules were moved to common/tuners, a separate customize option were added for tuners. However, the automatic selection of the tuners were still using the older option. This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the tuners. This patch fixes this error by replacing DVB_FE_CUSTOMISE by MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected. The patch were generated by this small script: for i in `find drivers/media -name Kconfig`; do cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a mv a $i done Also, manually reordered the tuner entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At some point the Flexcop driver was changed to support newer Flexcop cards. These modifications however broke the detection of Cablestar 2 DVB-C cards. The reason is that the earlier version of the driver used to retry unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297) seems to be very dependent on these retries and adding them back fixes Cablestar detection. This patch restores this behaviour for the CableStar2.

* | | edac: fix edac core deadlock when removing a deviceHarry Ciao2008-12-23

Since we have no idea which work in current edac_poller's workqueue is the work we are conerned about, we wait for all work in the edac_poller's workqueue to be proceseed. This is done via flush_cpu_workqueue() which inserts a wq_barrier into the tail of the workqueue and then sleeping on the completion of this wq_barrier. The edac_poller will wake up sleepers when it is found. EDAC core creates only one kernel worker thread, edac_poller, to run the works of all current edac devices. They share the same callback function of edac_device_workq_function(), which would grab the mutex of device_ctls_mutex first before it checks the device. This is exactly where edac_poller and rmmod would have a great chance to deadlock. In below call trace of rmmod > ... > edac_device_del_device > edac_device_workq_teardown > flush_workqueue > flush_cpu_workqueue, device_ctls_mutex would have already been grabbed by edac_device_del_device(). So, on one hand rmmod would sleep on the completion of a wq_barrier, holding device_ctls_mutex; on the other hand edac_poller would be blocked on the same mutex when it's running any one of works of existing edac evices(Note, this edac_dev.work is likely to be totally irrelevant to the one that is being removed right now)and never would have a chance to run the work of above wq_barrier to wake rmmod up. edac_device_workq_teardown() should not be called within the critical region of device_ctls_mutex. Just like is done in edac_pci_del_device() and edac_mc_del_mc(), where edac_pci_workq_teardown() and edac_mc_workq_teardown() are called after related mutex are released. Moreover, an edac_dev.work should check first if it is being removed. If this is the case, then it should bail out immediately. Since not all of existing edac devices are to be removed, this "shutting flag" should be contained to edac device being removed. The current edac_dev.op_state can be used to serve this purpose. The original deadlock problem and the solution have been witnessed and tested on actual hardware. Without the solution, rmmod an edac driver would result in below deadlock: root@localhost:/root> rmmod mv64x60_edac EDAC DEBUG: mv64x60_dma_err_remove() EDAC DEBUG: edac_device_del_device() EDAC DEBUG: find_edac_device_by_dev() (hang for a moment) INFO: task edac-poller:2030 blocked for more than 120 seconds.

Also, This sets the default level to "info", which is what all the ACPI drivers use. So to enable messages from drivers, you only have to supply the "layer" (a.k.a. "component"). For non-"info" ACPI core and ACPI interpreter messages, you have to supply both level and layer masks, as before.
