Revert "ACPICA: executer/exsystem: Warn about sleeps greater than 10 ms"

2022-05-21T16:02:26Z

Commit 6eaf08770ee8 ("ACPICA: executer/exsystem: Warn about sleeps greater than 10 ms") made acpi_ex_system_do_sleep() log a warning for sleep times greater than 10 ms, but such sleep times are used in power management AML because of the PCI specification requirements. This results with logging warnings that cannot really be acted on in any useful way which is annoying and these warnings show up in the logs on many production systems, so revert commit 6eaf08770ee8.

ACPICA: executer/exsystem: Warn about sleeps greater than 10 ms

2022-04-13T18:24:58Z

ACPICA commit 2a0d1d475e7ea1c815bee1e0692d81db9a7c909c Quick boottime is important, so warn about sleeps greater than 10 ms. Distribution Linux kernels reach initrd in 350 ms, so excessive delays should be called out. 10 ms is chosen randomly, but three of such delays would already make up ten percent of the boottime.

ACPICA: executer/exsystem: Inform users about ACPI spec violation

2022-04-13T18:24:58Z

ACPICA commit 05ba545ce7859392250b18c10081db25c90ed8d7 Values greater than 100 microseconds violate the ACPI specification, so warn users about it. From ACPI Specification version 6.2 Errata A, 19.6.128 *Stall (Stall for a Short Time)*: > The implementation of Stall is OS-specific, but must not relinquish > control of the processor. Because of this, delays longer than 100 > microseconds must use Sleep instead of Stall. Link: https://github.com/acpica/acpica/commit/05ba545c Signed-off-by: Bob Moore Signed-off-by: Rafael J.

ACPICA: executer/exsystem: Add units to time variable names

2022-04-13T18:24:57Z

ACPICA commit b69cbef7a83eadb102a1ff6c6f6fc5abce34805a `how_long` refers to different units in both functions, so make it more clear, what unit they expect. That also makes one comment superfluous.
