2023-06-08drm/msm/dp: enable HDP plugin/unplugged interrupts at hpd_enable/disableKuogee Hsieh3-54/+35
The internal_hpd flag is set to true by dp_bridge_hpd_enable() and set to false by dp_bridge_hpd_disable() to handle GPIO pinmuxed into DP controller case. HDP related interrupts can not be enabled until internal_hpd is set to true. At current implementation dp_display_config_hpd() will initialize DP host controller first followed by enabling HDP related interrupts if internal_hpd was true at that time. Enable HDP related interrupts depends on internal_hpd status may leave system with DP driver host is in running state but without HDP related interrupts being enabled. This will prevent external display from being detected. Eliminated this dependency by moving HDP related interrupts enable/disable be done at dp_bridge_hpd_enable/disable() directly regardless of internal_hpd status.

Wait for AON bit in HOST_SS_CPR_RST_CLR to return 0 before starting VPUIP power up sequence, otherwise the VPU device may sporadically fail to boot. An error in power up sequence is propagated to the runtime power management - the device will be in an error state until the VPU driver is reloaded.

2023-06-08accel/ivpu: Do not trigger extra VPU reset if the VPU is idleAndrzej Kacprowski1-4/+5
Turning off the PLL and entering D0i3 will reset the VPU so an explicit IP reset is redundant. But if the VPU is active, it may interfere with PLL disabling and to avoid that, we have to issue an additional IP reset to silence the VPU before turning off the PLL.

2023-06-07drm/amd: Disallow s0ix without BIOS support againMario Limonciello1-2/+6
commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed improvements to power consumption over suspend when s0ix wasn't enabled in BIOS and the system didn't support S3. This patch however was misguided because the reason the system didn't support S3 was because SMT was disabled in OEM BIOS setup. This prevented the BIOS from allowing S3. Also allowing GPUs to use the s2idle path actually causes problems if they're invoked on systems that may not support s2idle in the platform firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails for any reason, which could lead to unexpected flows. The original commit also fixed a problem during resume from suspend to idle without hardware support, but this is no longer necessary with commit ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven") Revert commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") to make it match the expected behavior again.

2023-06-05drm/i915/gt: Use the correct error value when kernel_context() failsAndi Shyti1-4/+8
kernel_context() returns an error pointer. Use pointer-error conversion functions to evaluate its return value, rather than checking for a '0' return.

2023-06-03leds: qcom-lpg: Fix PWM period limitsBjorn Andersson1-4/+4
The introduction of high resolution PWM support changed the order of the operations in the calculation of min and max period. The result in both divisions is in most cases a truncation to 0, which limits the period to the range of [0, 0]. Both numerators (and denominators) are within 64 bits, so the whole expression can be put directly into the div64_u64, instead of doing it partially.

Since the event-filter-function.tc expects the 'exit_mmap()' directly calls 'kmem_cache_free()', this is vulnerable to code modifications. Choose the target function for the filter test from the sample event data so that it can keep test running correctly even if the caller function name will be changed.

2023-06-02KVM: selftests: Add test for race in kvm_recalculate_apic_map()Michal Luczaj2-0/+75
Keep switching between LAPIC_MODE_X2APIC and LAPIC_MODE_DISABLED during APIC map construction to hunt for TOCTOU bugs in KVM. KVM's optimized map recalc makes multiple passes over the list of vCPUs, and the calculations ignore vCPU's whose APIC is hardware-disabled, i.e. there's a window where toggling LAPIC_MODE_DISABLED is quite interesting.
