2019-12-23clk: samsung: exynos5420: Keep top G3D clocks enabledMarek Szyprowski
In Exynos542x/5800 SoCs, the G3D leaf clocks are located in the G3D power domain. This is similar to the other hardware modules and their power domains. However there is one thing specific to G3D clocks hierarchy. Unlike other hardware modules, the G3D clocks hierarchy doesn't have any gate clock between the TOP part of the hierarchy and the part located in the power domain and some SoC internal busses are sourced directly from the TOP muxes. The consequence of this design if the fact that the TOP part of the hierarchy has to be enabled permanently to ensure proper operation of the SoC power related components (G3D power domain and Exynos Power Management Unit for system suspend/resume). This patch adds an explicit call to clk_prepare_enable() on the last MUX in the TOP part of G3D clock hierarchy to keep it enabled permanently to ensure that the internal busses get their clock regardless of the main G3D clock enablement status. This fixes following imprecise abort issue observed on Odroid XU3/XU4 after enabling Panfrost driver by commit 1a5a85c56402 "ARM: dts: exynos: Add Mali/GPU node on Exynos5420 and enable it on Odroid XU3/4"): panfrost 11800000.gpu: clock rate = 400000000 panfrost 11800000.gpu: failed to get regulator: -517 panfrost 11800000.gpu: regulator init failed -517 Power domain G3D disable failed ... panfrost 11800000.gpu: clock rate = 400000000 8<--- cut here --- Unhandled fault: imprecise external abort (0x1406) at 0x00000000 pgd = (ptrval) [00000000] *pgd=00000000 Internal error: : 1406 [#1] PREEMPT SMP ARM Modules linked in: CPU: 7 PID: 53 Comm: kworker/7:1 Not tainted 5.4.0-rc8-next-20191119-00032-g56f1001191a6 #6923 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) Workqueue: events deferred_probe_work_func PC is at panfrost_gpu_soft_reset+0x94/0x110 LR is at ___might_sleep+0x128/0x2dc ...

2019-12-23ALSA: hda - Apply sync-write workaround to old Intel platforms, tooTakashi Iwai
Klaus Ethgen reported occasional high CPU usages in his system that seem caused by HD-audio driver. The perf output revealed that it's in the unsolicited event handling in the workqueue, and the problem seems triggered by some communication stall between the controller and the codec at the runtime or system resume. Actually a similar phenomenon was seen in the past for other Intel platforms, and we already applied the workaround to enforce sync-write for CORB/RIRB verbs for Skylake and newer chipsets (commit 2756d9143aa5 "ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips"). Fortunately, the same workaround is applicable to the old chipset, and the experiment showed the positive effect. Based on the experiment result, this patch enables the sync-write workaround for all Intel chipsets. The only reason I hesitated to apply this workaround was about the possibly slightly higher CPU usage. But if the lack of sync causes a much severer problem even for quite old chip, we should think this would be necessary for all Intel chips.

2019-12-23rseq/selftests: Clarify rseq_prepare_unload() helper requirementsMathieu Desnoyers
The rseq.h UAPI now documents that the rseq_cs field must be cleared before reclaiming memory that contains the targeted struct rseq_cs, but also that the rseq_cs field must be cleared before reclaiming memory of the code pointed to by the rseq_cs start_ip and post_commit_offset fields. While we can expect that use of dlclose(3) will typically unmap both struct rseq_cs and its associated code at once, nothing would theoretically prevent a JIT from reclaiming the code without reclaiming the struct rseq_cs, which would erroneously allow the kernel to consider new code which is not a rseq critical section as a rseq critical section following a code reclaim.

2019-12-23kunit: Place 'test.log' under the 'build_dir'SeongJae Park
'kunit' writes the 'test.log' under the kernel source directory even though a 'build_dir' option is given. As users who use the option might expect the outputs to be placed under the specified directory, this commit modifies the logic to write the log file under the 'build_dir'.

2019-12-23kunit: Create default config in '--build_dir'SeongJae Park
If both '--build_dir' and '--defconfig' are given, the handling of '--defconfig' ignores '--build_dir' option. This commit modifies the behavior to respect '--build_dir' option.

2019-12-23docs/kunit/start: Use in-tree 'kunit_defconfig'SeongJae Park
The kunit doc suggests users to get the default `kunitconfig` from an external git tree. However, the file is already located under the `arch/um/configs/` of the kernel tree. Because the local file is easier to access and maintain, this commit updates the doc to use it.

livepatch test configures the system and debug environment to run tests. Some of these actions fail without root access and test dumps several permission denied messages before it exits. Fix test-state.sh to call setup_config instead of set_dynamic_debug as suggested by Petr Mladek <pmladek@suse.com> Fix it to check root uid and exit with skip code instead.

This function is only called from port sync and it is identical to what will be executed again in intel_update_crtc() over port sync pipes. If it is really necessary at least it deserves a better name and a comment, leaving it to people working on port sync.
