Module Name: src Committed By: riastradh Date: Wed Apr 12 06:39:16 UTC 2023
Modified Files: src/sys/arch/amd64/conf: GENERIC src/sys/arch/x86/pci: files.pci ichlpcib.c tco.c tco.h src/sys/dev/ic: i82801lpcreg.h src/sys/dev/pci: files.pci ichsmb.c Log Message: ichsmb(4), tco(4): Add support for TCO on newer Intel chipsets. TCO (`Total Cost of Ownership', Intel's bizarre name for a watchdog timer) used to hang off the Intel I/O platform controller hub's (ICH) low-pin-count interface bridge (LPC IB), or ichlpcib(4). On newer devices, it hangs off the ICH SMBus instead. Tested on INTEL 100SERIES_SMB (works) and INTEL 100SERIES_LP_SMB (doesn't work, still not sure why). XXX kernel revbump: This breaks the module ABI -- tco(4) modules older than the change to make ta_has_rcba into ta_version will incorrectly attach at buses they do not understand. (However, the tco(4) driver is statically built into GENERIC, so maybe it's safe for pullup since the module wouldn't have worked anyway.)
