https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=191564 Bug ID: 191564 Summary: [vt] UEFI boot shows that screen is not cleared as kernel starts Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: emaste@freebsd.org Created attachment 144346 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=144346&action=edit screenshot of UEFI vt(4) boot The UEFI loader uses UEFI's console services for I/O; the vt_efifb driver takes over for vt(4)'s framebuffer when the kernel boots, but does not clear the screen first, so some of the previous output remains on screen until it is scrolled off. See the attached screenshot - the loader's output finished with "Start @ 0xffff...." at the bottom, and the kernel's output started with "GDB: no debug ports present" at the top. -- You are receiving this mail because: You are the assignee for the bug.
