* drm/i915: lock correct mutex around object unreference.Dave Airlie2009-01-16
| | | | | | This makes sure the mutex is held around the unreference. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/i915: add support for physical memory objectsDave Airlie2009-01-16
| | | | | | | | | | | | | | This is an initial patch to do support for objects which needs physical contiguous main ram, cursors and overlay registers on older chipsets. These objects are bound on cursor bin, like pinning, and we copy the data to/from the backing store object into the real one on attach/detach. notes: possible over the top in attach/detach operations. no overlay support yet.

* drm: initial KMS config fixesJesse Barnes2009-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When mode setting is first initialized, the driver will call into drm_helper_initial_config() to set up an initial output and framebuffer configuration. This routine is responsible for probing the available connectors, encoders, and crtcs, looking for modes and putting together something reasonable (where reasonable is defined as "allows kernel messages to be visible on as many displays as possible"). However, the code was a bit too aggressive in setting default modes when none were found on a given connector. Even if some connectors had modes, any connectors found lacking modes would have the default 800x600 mode added to their mode list, which in some cases could cause problems later down the line. In my case, the LVDS was perfectly available, but the initial config code added 800x600 modes to both of the detected but unavailable HDMI connectors (which are on my non-existent docking station). This ended up preventing later code from setting a mode on my LVDS, which is bad. This patch fixes that behavior by making the initial config code walk through the connectors first, counting the available modes, before it decides to add any default modes to a possibly connected output. It also fixes the logic in drm_target_preferred() that was causing zeroed out modes to be set as the preferred mode for a given connector, even if no modes were available.

* drm/i915: set vblank enabled flag correctly across IRQ install/uninstallJesse Barnes2009-01-10
| | | | | | | | | | | | | | | | | | | In the absence of kernel mode setting, many drivers disable IRQs across VT switch. The core DRM vblank code is missing a check for this case however; even after IRQ disable, the vblank code will still have the vblank_enabled flag set, so unless we track the fact that they're disabled at IRQ uninstall time, when we VT switch back in we won't actually re-enable them, which means any apps waiting on vblank before the switch will hang. This patch does that and also adds a sanity check to the wait condition to look for the irq_enabled flag in general, as well as adding a wakeup to the IRQ uninstall path. Fixes fdo bug #18879 with compiz hangs at VT switch. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Dave Airlie <airlied@linux.ie>

* | Check fops_get() return valueLaurent Pinchart2009-01-06
|/ | | | | | | | | | | | | | | | | | | | | | 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.

* 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.
