[PATCH] drm: avoid spurious EBUSY due to nonblocking atomic modesets

by Daniel Vetter

When doing an atomic modeset with ALLOW_MODESET drivers are allowed to pull in arbitrary other resources, including CRTCs (e.g. when reconfiguring global resources). But in nonblocking mode userspace has then no idea this happened, which can lead to spurious EBUSY calls, both: - when that other CRTC is currently busy doing a page_flip the ALLOW_MODESET commit can fail with an EBUSY - on the other CRTC a normal atomic flip can fail with EBUSY because of the additional commit inserted by the kernel without userspace's knowledge For blocking commits this isn't a problem, because everyone else will just block until all the CRTC are reconfigured. Only thing userspace can notice is the dropped frames without any reason for why frames got dropped. Consensus is that we need new uapi to handle this properly, but no one has any idea what exactly the new uapi should look like. As a stop-gap plug this problem by demoting nonblocking commits which might cause issues by including CRTCs not in the original request to blocking commits. v2: Add comments and a WARN_ON to enforce this only when allowed - we don't want to silently convert page flips into blocking plane updates just because the driver is buggy.

I hope the "Fixes" tag will work, but yeah, my bad, cc:stable is definitely a good idea here. Added stable@ to cc. Thanks!

[PATCH 1/2] i2c: i801: Fix runtime PM

by Jarkko Nikula

Commit 9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") nullified the runtime PM suspend/resume callback pointers while keeping the runtime PM enabled. This causes that device stays in D0 power state and sysfs /sys/bus/pci/devices/.../power/runtime_status shows "error" when runtime PM framework attempts to autosuspend the device. This is due PCI bus runtime PM which checks for driver runtime PM callbacks and returns with -ENOSYS if they are not set. Fix this by having a shared dummy runtime PM callback that returns with success.

[PATCH] ARM: tegra: Fix restoration of PLLM when exiting suspend

by Jon Hunter

The suspend entry and exit code for 32-bit Tegra devices assumes that the PLLM (which is used to provide the clock for external memory) is always enabled on entry to suspend. Hence, the current code always disables the PLLM on entry to suspend and re-enables the PLLM on exit from suspend. Since the introduction of the Tegra124 EMC driver by commit 73a7f0a90641 ("memory: tegra: Add EMC (external memory controller) driver"), which is used to scale the EMC frequency, PLLM may not be the current clock source for the EMC on entry to suspend and hence may not be enabled. Always enabling the PLLM on exit from suspend can cause the actual status on the PLL to be different from that reported by the common clock framework. On kernels prior to v4.5, the code to set the rate of the PLLM had a test to verify if the PLL was enabled and if the PLL was enabled, setting the rate would fail. Since commit 267b62a96951 ("clk: tegra: pll: Update PLLM handling") the test to see if PLLM is enabled was removed. With these earlier kernels, if the PLLM is disabled on entering suspend and the EMC driver attempts to set the parent of the EMC clock to the PLLM on exiting suspend, then the set rate for the PLLM will fail and in turn cause the resume to fail. We should not be re-enabling the PLLM on resume from suspend unless it was enabled on entry to suspend. Therefore, fix this by saving the state of PLLM on entry to suspend and only re-enable it, if it was already enabled.
