2016-11-02drm/msm/mdp5: no scaling support on RGBn pipes for 8x16Rob Clark2-7/+4
Looks like cut/paste error from the other device cfgs (which do support scaling on RGBn pipes). Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-11-02drm/msm/mdp5: handle non-fullscreen base plane caseRob Clark1-18/+28
If the bottom-most layer is not fullscreen, we need to use the BASE mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT). The blend_setup() code pretty much handled this already, we just had to figure this out in _atomic_check() and assign the stages appropriately. Also fix the case where there are zero enabled planes, where we also need to enable BORDER_OUT. Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-11-02drm/msm: Set CLK_IGNORE_UNUSED flag for PLL clocksArchit Taneja4-0/+4
The DSI/HDMI PLLs in MSM require resources like interface clocks, power domains to be enabled before we can access their registers. The clock framework doesn't have a mechanism at the moment where we can tie such resources to a clock, so we make sure that the KMS driver enables these resources whenever a PLL is expected to be in use. One place where we can't ensure the resource dependencies are met is when the clock framework tries to disable unused clocks. The KMS driver doesn't know when the clock framework calls the is_enabled clk_op, and hence can't enable interface clocks/power domains beforehand. We set the CLK_IGNORE_UNUSED flag for PLL clocks for now. This needs to be revisited, since bootloaders can enable display, and we would want to disable the PLL clocks if there isn't a display driver using them.

2016-11-02drm/msm/dsi: Queue HPD helper work in attach/detach callbacksArchit Taneja1-2/+12
The msm/dsi host drivers calls drm_helper_hpd_irq_event in the mipi_dsi_host attach/detatch callbacks. mipi_dsi_attach()/mipi_dsi_detach() from a panel/bridge driver could be called from a context where the drm_device's mode_config.mutex is already held, resulting in a deadlock. Queue it as work instead. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-11-01drm/nouveau/acpi: fix check for power resources supportPeter Wu1-1/+2
Check whether the kernel really supports power resources for a device, otherwise the power might not be removed when the device is runtime suspended (DSM should still work in these cases where PR does not). This is a workaround for a problem where ACPICA and Windows 10 differ in behavior. ACPICA does not correctly enumerate power resources within a conditional block (due to delayed execution of such blocks) and as a result power_resources is set to false even if _PR3 exists.

2016-10-29x86/smpboot: Init apic mapping before usageThomas Gleixner1-1/+6
The recent changes, which forced the registration of the boot cpu on UP systems, which do not have ACPI tables, have been fixed for systems w/o local APIC, but left a wreckage for systems which have neither ACPI nor mptables, but the CPU has an APIC, e.g. virtualbox. The boot process crashes in prefill_possible_map() as it wants to register the boot cpu, which needs to access the local apic, but the local APIC is not yet mapped. There is no reason why init_apic_mapping() can't be invoked before prefill_possible_map(). So instead of playing another silly early mapping game, as the ACPI/mptables code does, we just move init_apic_mapping() before the call to prefill_possible_map(). In hindsight, I should have noticed that combination earlier. Sorry for the churn (also in stable)!

2016-10-28ARC: module: elide loop to save reference to .eh_frameVineet Gupta2-10/+9
The loop was really needed in .debug_frame regime where wanted make it as SH_ALLOC so that apply_relocate_add() would process it. That's not needed for .eh_frame, so we check this in apply_relocate_add() which gets called for each section. Note that we need to save reference to "section name strings" section in module_frob_arch_sections() since apply_relocate_add() doesn't get that Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2016-10-28ARC: boot log: refactor cpu name/release printingVineet Gupta3-24/+34
The motivation is to identify ARC750 vs. ARC770 (we currently print generic "ARC700"). A given ARC700 release could be 750 or 770, with same ARCNUM (or family identifier which is unfortunate). The existing arc_cpu_tbl[] kept a single concatenated string for core name and release which thus doesn't work for 750 vs. 770 identification. So split this into 2 tables, one with core names and other with release. And while we are at it, get rid of the range checking for family numbers. We just document the known to exist cores running Linux and ditch others. With this in place, we add detection of ARC750 which is - cores 0x33 and before - cores 0x34 and later with MMUv2 Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2016-10-28ARC: boot log: refactor printing abt features not captured in BCRsVineet Gupta2-45/+43
On older arc700 cores, some of the features configured were not present in Build config registers. To print about them at boot, we just use the Kconfig option i.e. whether linux is built to use them or not. So yes this seems bogus, but what else can be done. Moreover if linux is booting with these enabled, then the Kconfig info is a good indicator anyways. Over time these "hacks" accumulated in read_arc_build_cfg_regs() as well as arc_cpu_mumbojumbo(). so refactor and move all of those in a single place: read_arc_build_cfg_regs(). This causes some code redcution too: | bloat-o-meter2 arch/arc/kernel/setup.o.0 arch/arc/kernel/setup.o.1 | add/remove: 0/0 grow/shrink: 2/1 up/down: 64/-132 (-68) | function old new delta | setup_processor 610 670 +60 | cpuinfo_arc700 76 80 +4 | arc_cpu_mumbojumbo 752 620 -132 Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
