2009-11-25drm/i915: Select CONFIG_SHMEMChris Wilson
The driver requires shmfs as the backing filesystem to handle the buffer objects, so ensure it is selected if the user chooses to build our driver. Fixes: Bug 14662 - Dell E5500 kernel panic with KMS http://bugzilla.kernel.org/show_bug.cgi?id=14662 The revealing nature of the panic is the NULL function pointer dereference in read_cache_page_async().

2009-11-25drm/i915: Fix CRT hotplug detect by checking really no channels attachedZhenyu Wang
For CRT hotplug detect status, we have four test results as blue channel only, green channel only, both blue and green channel, and no channel attached. Origin code only marks both blue and green channel case as connected, but ignore other possible connected states. This one trys to detect CRT by checking no channel attached case instead.

2009-11-24drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handlingClemens Ladisch
When the framebuffer driver does not publish detailed timing information for the current video mode, the correct value for the pixclock field is zero, not -1. Since pixclock is actually unsigned, the value -1 would be interpreted as 4294967295 picoseconds (i.e., about 4 milliseconds) by register_framebuffer() and userspace programs. This patch allows X.org's fbdev driver to work.

2009-11-24drm: make sure page protections are updated after changing vm_flagsJeremy Fitzhardinge
Some architectures compute ->vm_page_prot depending on ->vm_flags, so we need to update the protections after adjusting the flags. AFAIK this only affects running X under Xen; without this patch you get lots of coloured blobs on the screen, or maybe a complete lockup. Or anything really. But that still depends on lots of out-of-tree stuff, so I don't think there are any consequences for anyone else. But it is wrong in principle.

2009-11-24drm/radeon/kms: Report vga connector is connected according to ddc_probeJerome Glisse
On broken EDID we were reporting vga connector to be disconnected even if ddc probe did found a monitor. This patch report that the connector is connected on such case. This allow drm to add a fail safe mode (800x600 at the time of this patch) thus user can boot and later add a mode which match its monitor capabilities.

2009-11-24drm: mm always protect change to unused_nodes with unused_lock spinlockJerome Glisse
unused_nodes modification needs to be protected by unused_lock spinlock. Here is an example of an usage where there is no such protection without this patch. Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list) 2-spin_lock(spinlock protecting mm struct) 3-drm_mm_put_block(this function might modify unused_nodes list but doesn't protect modification with unused_lock) 4-spin_unlock(spinlock protecting mm struct) Process2: 1-drm_mm_pre_get(this function modify unused_nodes list) At this point Process1 & Process2 might both be doing modification to unused_nodes list. This patch add unused_lock protection into drm_mm_put_block to avoid such issue. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-11-24drm/radeon/kms: Disable TV load detect on RS400,RC410,RS480Jerome Glisse
RS400,RC410,RS480 chipset seems to report a lot of false positive with load detect on TV output. We haven't yet found a way to make load detect reliable on those chipset, thus just disable it for TV output. Would avoid user to experience phantom screen because X believe there is a monitor connected to the TV output.

2009-11-24drm/radeon/kms: read back register before writing in IIO.Dave Airlie
This fixes RH bugzilla #527874. On resume the atom posting wasn't working, however vbe posting was going fine, after 2 weeks over irc, and 8 hrs with the hardware, I tracked it down to the memory device table and it access the MC registers via IIO, it appears the rv515 atom iio table might not be fully functional, so adding a readback before doing a write either provides enough delay to make things resume correctly.

2009-11-24drm/radeon/kms: resume AGP by calling init.Dave Airlie
AGP resume was broken since we moved to the new init path, because we never re-enabled AGP on these systems at resume time. This patch just calls the AGP resume call which just does the reinit at resume time like the old path did. Since AGP is pretty much gpu independant I did it outside the gpu specific code.

The Lenovo W500 laptop hangs inside an SMI on brightness changes, I thought it just needed the VGA disable but it turned out to require slightly more work, setting the MC locations up just like the IGP chip requirements seems to make it all happy again and I can boot and play with brightness.

2009-11-04drm/radeon/kms: fix coherency issues on AGP cards.Dave Airlie
When we are evicting from VRAM->RAM we allocate the ttm object, but we don't set the caching policy on it before blitting into it. This means on AGP we end up blitting into cached pages, and the CPU later flushes out on top of them. This was mostly seen as font corruption. The other question is why we don't evict VRAM->GTT in a lot of cases, this would save us some cache transitions since a lot of objects that are evicted from VRAM will probably end up being pulled back in a few operations later, and evicting them to system memory involves 2 unnecessary cache transitions.

2009-11-02i915: fix intel graphics suspend breakage due to resume/lid event confusionLinus Torvalds
In commit c1c7af60892070e4b82ad63bbfb95ae745056de0 ("drm/i915: force mode set at lid open time") the intel graphics driver was taught to restore the LVDS mode on lid open. That caused problems with interaction with the suspend/resume code, which commonly runs at the same time (suspend is often caused by the lid close event, while lid open is commonly a resume event), which was worked around with in commit 06891e27a9b5dba5268bb80e41a283f51335afe7 ("drm/i915: fix suspend/resume breakage in lid notifier"). However, in the meantime the lid event code had also grown a user event notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915: generate a KMS uevent at lid open/close time"), and now _that_ causes problems with suspend/resume and some versions of Xorg reacting to those uevents by setting the mode. So this effectively reverts that commit 06324194ee, and makes the lid open protection logic against suspend/resume more explicit. This fixes at least one laptop. See http://bugzilla.kernel.org/show_bug.cgi?id=14484 for more details.
