The branch main has been updated by ngie: URL: https://cgit.FreeBSD.org/src/commit/?id=f224591746bdaf14ad5f63de4738a3146cc2f55f commit f224591746bdaf14ad5f63de4738a3146cc2f55f Author: Enji Cooper <ngie@FreeBSD.org> AuthorDate: 2026-01-04 08:27:57 +0000 Commit: Enji Cooper <ngie@FreeBSD.org> CommitDate: 2026-01-06 01:43:04 +0000 Add ASMC_DEBUG make option This allows folks to enable debug statements in asmc(4) using kernel configs via the `options ASMC_DEBUG` directive. While here, remove a duplicate `device vt_efifb` directive in `NOTES` as it's already handled in the `GENERIC` config MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D54511 --- sys/amd64/conf/NOTES | 7 ++++--- sys/conf/options.amd64 | 3 +++ sys/dev/asmc/asmc.c | 20 +++++++++++--------- sys/modules/asmc/Makefile | 2 +- 4 files changed, 19 insertions(+), 13 deletions(-) diff --git a/sys/amd64/conf/NOTES b/sys/amd64/conf/NOTES index d48fd10c0e62..efcc03623c05 100644 --- a/sys/amd64/conf/NOTES +++ b/sys/amd64/conf/NOTES @@ -43,9 +43,6 @@ cpu HAMMER # aka K8, aka Opteron & Athlon64 # Optional devices: # -# vt(4) drivers. -device vt_efifb # EFI framebuffer - # 3Dfx Voodoo Graphics, Voodoo II /dev/3dfx CDEV support.
