Sorry for multiposting, as I can't guess where is the right list to post. I've written a driver for ACPI WDAT (Watchdog Action Table) based watchdog timer and I want this driver to be included in the future FreeBSD versions. Please someone tell me how should I do.
Simply said, WDAT is an abstraction for the real WDT hardware. For instance, to add a newer generation WDT to ichwd(4), one must know the detailed hardware registers, etc.. Actually I tried to add Apollo Lake Celeron and Coffee Lake Xeon support to ichwd(4) and I couldn't. With WDAT, the necessary IO port accesses to operate the WDT are comprehensively described in it and no hardware knowledge is required. With this driver, I have successfully managed to use the WDT on Advantech ARK-1124C, Dell R210 and Dell R240. * R210 is also supported by ichwd(4). Others are not supported yet. The unfortunate thing is that not all systems have WDAT defined. Thanks in advance for your attention. -- Tetsuya Uemura <t_uem...@macome.co.jp>
