* drm/radeon/kms: consolidate GART code, fix segfault after GPU lockup V2Jerome Glisse2011-11-04
| | | | | | | | | | | | | | After GPU lockup VRAM gart table is unpinned and thus its pointer becomes unvalid. This patch move the unpin code to a common helper function and set pointer to NULL so that page update code can check if it should update GPU page table or not. That way bo still bound to GART can be unbound (pci_unmap_page for all there page) properly while there is no need to update the GPU page table. V2 move the test for null gart out of the loop, small optimization Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm/radeon/kms: set HPD polarity in hpd_init()Alex Deucher2011-11-03
| | | | | | | | | | | | Polarity needs to be set accordingly to connector status (connected or disconnected). Set it up in hpd_init() so first hotplug works reliably no matter what is the initial set of connector. hpd_init() also covers resume so HPD will work correctly after resume as well.

* drm/radeon/kms: add MSI module parameterAlex Deucher2011-11-03
| | | | | | | | | | | | | | | | | | Allow the user to override whether MSIs are enabled or not on supported ASICs. MSIs are disabled by default on IGP chips as they tend not to work. However certain IGP chips only seem to work with MSIs enabled. I suspect this is a chipset or bios issue, but I'm not sure what the proper fix is. This will at least make diagnosing and working around the problem much easier.

* vmwgfx: Reinstate the update_layout ioctlThomas Hellstrom2011-11-02
| | | | | | | | | | | | | | | | | | | | | | | | We need to redefine a connector as "connected" if it matches a window in the host preferred GUI layout. Otherwise "smart" window managers would turn on Xorg outputs that we don't want to be on. This reinstates the update_layout and adds the following information to the modesetting system. a) Connection status <-> Equivalent to real hardware connection status b) Preferred mode <-> Equivalent to real hardware reading EDID c) Host window position <-> Equivalent to a real hardware scanout address dynamic register. It should be noted that there is no assumption here about what should be displayed and where. Only how to access the host windows. This also bumps minor to signal availability of the new IOCTL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 47356eb67285014527a5ab87543ba1fae3d1e10a introduced a mechanism to record the backlight level only at disabling time, but it also introduced a regression. Since intel_lvds_enable() may be called without disabling (e.g. intel_lvds_commit() calls it unconditionally), the backlight gets back to the last recorded value. For example, this happens when you dim the backlight, close the lid and open the lid, then the backlight suddenly goes to the brightest. This patch fixes the bug by recording the backlight level always when changed via intel_panel_set_backlight(). And, intel_panel_{enable|disable}_backlight() call the internal function not to update the recorded level wrongly.

| | * drm/i915: fix transcoder PLL select maskingJesse Barnes2011-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transcoder A will always use PLL A and transcoder B will use PLL B. But transcoder C could use either, so always mask the select bits off before or'ing in a new value.
