2015-01-27drm/nv4c/mc: disable msiIlia Mirkin
commit 4761703bd04bbdf56396d264903cc5a1fdcb3c01 upstream. Several users have, over time, reported issues with MSI on these IGPs. They're old, rarely available, and MSI doesn't provide such huge advantages on them. Just disable.

2014-09-17drm/nouveau: Bump version from 1.1.1 to 1.1.2Mario Kleiner
commit 7820e5eef0faa4a5e10834296680827f7ce78a89 upstream. Linux 3.16 fixed multiple bugs in kms pageflip completion events and timestamping, which were originally introduced in Linux 3.13. These fixes have been backported to all stable kernels since 3.13. However, the userspace nouveau-ddx needs to be aware if it is running on a kernel on which these bugs are fixed, or not. Bump the patchlevel of the drm driver version to signal this, so backporting this patch to stable 3.13+ kernels will give the ddx the required info.

2014-07-09drm/nv50-/mc: fix kms pageflip events by reordering irq handling order.Mario Kleiner
commit dcfb1009df3b4ad8d2e0779dd45b438629d6858a upstream. Whenever a single nouveau_mc_intr() main gpu irq-handler invocation was responsible for calling both, the vblank-irq handler (display engine irq) and kms-pageflip completion handler (from fifo irq), the order of invocation was wrong. nouveau_finish_flip() was called before drm_handle_vblank() for the vblank of pageflip completion, so the emitted pageflip event contained stale vblank count and timestamp from previous vblank. This caused failure in userspace to timestamp properly. Reorder order of invocation of engine irq handlers: Put NVDEV_ENGINE_DISP always on top, and thereby before NVDEV_ENGINE_FIFO, so that drm_handle_vblank() gets called to update vblank timestamps and count before potential pageflip events make use of that information. This works on nv-50 and later, where kms-pageflip completion triggers an irq either after a separate vblank irq, or both pageflip and vblank trigger one common irq invocation, but never before vblank irqs. v2 (Ben): - removed mods for nv04-nv40, it doesn't help there anyway - this is considered a hack, and a better solution should be found Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit e291af3f2259e9e105dfd72416fd5796513791a4 upstream. nv04_disp_scanoutpos() must abort to trigger simple timestamping fallback if vtotal/htotal regs return zero. This happens if the output isn't a digital output, but a vga analog output, as the regs don't get initialized in that case. Fixes timestamping failure on nv-40 and earlier with vga output.

commit af4870e406126b7ac0ae7c7ce5751f25ebe60f28 upstream. Cards with nv04 display engine can't reliably use vblank counts and timestamps computed via drm_handle_vblank(), as the function gets invoked after sending the pageflip events.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "As far as the number of commits goes, the top spot belongs to ACPI this time with cpufreq in the second position and a handful of PM core, PNP and cpuidle updates. They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper.
