2019-05-14ACPI: PM: Set enable_for_wake for wakeup GPEs during suspend-to-idleRajat Jain
I noticed that recently multiple systems (chromebooks) couldn't wake from S0ix using LID or Keyboard after updating to a newer kernel. I bisected and it turned up commit f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle"). I checked that the issue got fixed if that commit was reverted. I debugged and found that although PNP0C0D:00 (representing the LID) is wake capable and should wakeup the system per the code in acpi_wakeup_gpe_init() and in drivers/acpi/button.c: localhost /sys # cat /proc/acpi/wakeup Device S-state Status Sysfs node LID0 S4 *enabled platform:PNP0C0D:00 CREC S5 *disabled platform:GOOG0004:00 *disabled platform:cros-ec-dev.1.auto *disabled platform:cros-ec-accel.0 *disabled platform:cros-ec-accel.1 *disabled platform:cros-ec-gyro.0 *disabled platform:cros-ec-ring.0 *disabled platform:cros-usbpd-charger.2.auto *disabled platform:cros-usbpd-logger.3.auto D015 S3 *enabled i2c:i2c-ELAN0000:00 PENH S3 *enabled platform:PRP0001:00 XHCI S3 *enabled pci:0000:00:14.0 GLAN S4 *disabled WIFI S3 *disabled pci:0000:00:14.3 localhost /sys # On debugging, I found that its corresponding GPE is not being enabled. The particular GPE's "gpe_register_info->enable_for_wake" does not have any bits set when acpi_enable_all_wakeup_gpes() comes around to use it. I looked at code and could not find any other code path that should set the bits in "enable_for_wake" bitmask for the wake enabled devices for s2idle. [I do see that it happens for S3 in acpi_sleep_prepare()]. Thus I used the same call to enable the GPEs for wake enabled devices, and verified that this fixes the regression I was seeing on multiple of my devices. [ rjw: The problem is that commit f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle") forgot to add the acpi_enable_wakeup_devices() call for s2idle along with acpi_enable_all_wakeup_gpes(). ] Fixes: f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle") Link: https://bugzilla.kernel.org/show_bug.cgi?id=203579 Signed-off-by: Rajat Jain <rajatja@google.com> [ rjw: Subject & changelog ] Cc: 5.0+ <stable@vger.kernel.org> # 5.0+ Signed-off-by: Rafael J.

2019-05-14backlight: lm3630a: Add firmware node supportBrian Masney
Add fwnode support to the lm3630a driver and optionally allow configuring the label, default brightness level, and maximum brightness level. The two outputs can be controlled by bank A and B independently or bank A can control both outputs. If the platform data was not configured, then the driver defaults to enabling both banks. This patch changes the default value to disable both banks before parsing the firmware node so that just a single bank can be enabled if desired. There are no in-tree users of this driver. Driver was tested on a LG Nexus 5 (hammerhead) phone.

I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero: twl6040 0-004b: Failed to write 2d = 19: -121 And then any following register access will produce errors. There 2d offset above is register ACCCTL that gets written on twl6040 powerup. With error checking added to the related regcache_sync() call, the -EREMOTEIO error is reproducable on twl6040 powerup at least duovero. To fix the error, we need to wait until twl6040 is accessible after the powerup. Based on tests on omap4 duovero, we need to wait over 8ms after powerup before register write will complete without failures. Let's also make sure we warn about possible errors too. Note that we have twl6040_patch[] reg_sequence with the ACCCTL register configuration and regcache_sync() will write the new value to ACCCTL.

2019-05-14perf/x86/intel: Allow PEBS multi-entry in watermark modeStephane Eranian
This patch fixes a restriction/bug introduced by: 583feb08e7f7 ("perf/x86/intel: Fix handling of wakeup_events for multi-entry PEBS") The original patch prevented using multi-entry PEBS when wakeup_events != 0. However given that wakeup_events is part of a union with wakeup_watermark, it means that in watermark mode, PEBS multi-entry is also disabled which is not the intent. This patch fixes this by checking is watermark mode is enabled.

2019-05-14drm/nouveau: fix duplication of nv50_head_atom structPeteris Rudzusiks
nv50_head_atomic_duplicate_state() makes a copy of nv50_head_atom struct. This patch adds copying of struct member named "or", which previously was left uninitialized in the duplicated structure. Due to this bug, incorrect nhsync and nvsync values were sometimes used. In my particular case, that lead to a mismatch between the output resolution of the graphics device (GeForce GT 630 OEM) and the reported input signal resolution on the display. xrandr reported 1680x1050, but the display reported 1280x1024. As a result of this mismatch, the output on the display looked like it was cropped (only part of the output was actually visible on the display). git bisect pointed to commit 2ca7fb5c1cc6 ("drm/nouveau/kms/nv50: handle SetControlOutputResource from head"), which added the member "or" to nv50_head_atom structure, but forgot to copy it in nv50_head_atomic_duplicate_state().

configuration Where possible, we want the failsafe link configuration (one which won't hang the OR during modeset because of not enough bandwidth for the mode) to also be supported by the sink. This prevents "link rate unsupported by sink" messages when link training fails. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2019-05-14drm/nouveau/core: initial support for boards with TU117 chipsetBen Skeggs
Modesetting only, still waiting on ACR/GR firmware from NVIDIA for Turing graphics/compute bring-up. Each subsystem was compared with traces, along with various tests to check that things generally work as they should, and appears compatible enough with the current TU106 code to enable support.
