Module Name:    src
Committed By:   rin
Date:           Thu Mar 25 05:33:59 UTC 2021

Modified Files:
        src/sys/dev/acpi: com_acpi.c
        src/sys/dev/ic: com.c comvar.h
        src/sys/dev/pci: com_puc.c

Log Message:
Introduce sc_poll_ticks and obsolete COM_HW_POLL bit in sc_hwflags.
Polling is scheduled at every sc_poll_ticks ticks.

This is useful to work around H/W bug, by which interrupts are lost
*sometimes*; interrupt-based I/O mostly works and no need for polling
every counter ticks.
