https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D262638 Bug ID: 262638 Summary: overly strict check of hpet region size Product: Base System Version: 13.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jfc@mit.edu FreeBSD warns during boot of my HPE Proliant DL325 (AMD EPYC 7402P): hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed001ff on acpi0 hpet0: memory region width 512 too small device_attach: hpet0 attach returned 6 The hpet driver requires at least 1024 bytes of address space. This appear= s to be overly strict because the address space used depends on the number of counters. See HPET_TIMER_CAP_CNF and related macros. My 512 byte address space should be sufficient for 8 counters. (I have not checked what the configuration registers say. I can hack up my kernel to report them if the answer is imporant.) --=20 You are receiving this mail because: You are the assignee for the bug.=
