2022-06-06platform/chrome: cros_ec_proto: update cros_ec_check_result() commentTzung-Bi Shih1-2/+5
At first glance, cros_ec_check_result() is quite like cros_ec_map_error(). They check for `ec_msg->result` and return corresponding errors. However, as calling from `pkt_xfer` and `cmd_xfer`, cros_ec_check_result() should not report furthermore errors. -EAGAIN is the only exception. See [1][2][3] for some known userland programs' code. The return code from ioctl only denotes the EC communication status. Userland programs would further analyze the `result` in struct cros_ec_command* for follow-up actions (e.g. [4]). To clarify, update the function comment.

Pull ptrace_stop cleanups from Eric Biederman: "While looking at the ptrace problems with PREEMPT_RT and the problems Peter Zijlstra was encountering with ptrace in his freezer rewrite I identified some cleanups to ptrace_stop that make sense on their own and move make resolving the other problems much simpler. The biggest issue is the habit of the ptrace code to change task->__state from the tracer to suppress TASK_WAKEKILL from waking up the tracee. No other code in the kernel does that and it is straight forward to update signal_wake_up and friends to make that unnecessary. Peter's task freezer sets frozen tasks to a new state TASK_FROZEN and then it stores them by calling "wake_up_state(t, TASK_FROZEN)" relying on the fact that all stopped states except the special stop states can tolerate spurious wake up and recover their state. The state of stopped and traced tasked is changed to be stored in task->jobctl as well as in task->__state. This makes it possible for the freezer to recover tasks in these special states, as well as serving as a general cleanup. With a little more work in that direction I believe TASK_STOPPED can learn to tolerate spurious wake ups and become an ordinary stop state. The TASK_TRACED state has to remain a special state as the registers for a process are only reliably available when the process is stopped in the scheduler. Fundamentally ptrace needs acess to the saved register values of a task. There are bunch of semi-random ptrace related cleanups that were found while looking at these issues. One cleanup that deserves to be called out is from commit 57b6de08b5f6 ("ptrace: Admit ptrace_stop can generate spuriuos SIGTRAPs"). This makes a change that is technically user space visible, in the handling of what happens to a tracee when a tracer dies unexpectedly.

2022-06-03firmware_loader: enable XZ by default if compressed support is enabledLinus Torvalds1-0/+1
Commit 23cfbc6ec44e ("firmware: Add the support for ZSTD-compressed firmware files") added support for ZSTD compression, but in the process also made the previously default XZ compression a config option. That means that anybody who upgrades their kernel and does a make oldconfig to update their configuration, will end up without the XZ compression that the configuration used to have. Add the 'default y' to make sure this doesn't happen. The whole compression question should probably be improved upon, since it is now possible to "enable" compression in the kernel config but not enable any actual compression algorithm, which makes it all very useless. It makes no sense to ask Kconfig questions that enable situations that are nonsensical like that. This at least fixes the immediate problem of a kernel update resulting in a nonbootable machine because of a missed option.

Pull initial Loongarch architecture code from Arnd Bergmann: "This is the majority of the loongarch architecture code, including the final system call interface and all core functionality. It still misses three sets of peripheral but vital patches to add support for other subsystems, which have yet to pass review: - The drivers/firmware/efi stub for booting from a standard UEFI firmware implementation. Both the original custom boot interface and a draft implementation of the EFI stub did not make it, so it is currently impossible to boot the kernel, until the loongarch specific portions get accepted into the UEFI subsystem - The drivers/irqchip/irq-loongson-*.c drivers are shared with the the MIPS port, but currently lack support for ACPI based booting, which will get merged through the irqchip subsystem. - Similarly, the drivers/pci/controller/pci-loongson.c needs to be modified for ACPI support, which will be merged through the PCI subsystem. While the port cannot actually be used before all the above are merged, having it in 5.19 helps to establish the user space ABI for the libc ports to build on, and to help any treewide changes in the mainline kernel get applied here as well.

2022-06-03drm/amd/display: FCLK P-state support updatesChaitanya Dhere2-5/+7
[Why] Previously we used to send FCLK P-state enable messages upon each call to update_clocks based on dml output. This resulted in increased message transactions between DC and PMFW. [How] Update the code to check safe_to_lower status and send the message based on dml input only on boot. This reduces message transactions. Also remove other unwanted code based on current code status. Signed-off-by: Chaitanya Dhere <chaitanya.dhere@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-06-03drm/amd/display: do not override CURSOR_REQ_MODE when SubVP is not enabledSamson Tam1-2/+5
[Why] HUBP_UNBOUNDED_REQ_MODE and CURSOR_REQ_MODE are normally set together. In hubp32_prepare_subvp_buffering() call, CURSOR_REQ_MODE is set based on whether SubVP is enabled or not. For non MPO case, both REQ_MODE registers are set to 1. But since SubVP is not enabled, then CURSOR_REQ_MODE is set to 0, overriding the previous value. [How] Do not set CURSOR_REQ_MODE to 0 if SubVP is not enabled. This will allow CURSOR_REQ_MODE to stay as 1 in the non MPO case. Add note to follow up and check case for single pipe MPO and SubVP enabled as this would cause both REQ_MODE registers to be set to 0 but SubVP enabled would override CURSOR_REQ_MODE to 1.
