https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290098 Chris Mecca <cm@chrismecca.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |cm@chrismecca.com --- Comment #24 from Chris Mecca <cm@chrismecca.com> --- Confirmed working on FreeBSD 15.0-RELEASE-p5 (amd64) with the patch attributed to Mark Peek reducing FB_SIZE from 32MB to 16MB in usr.sbin/bhyve/pci_fbuf.c. Tested with 9front-11498.c89461d55aa4.amd64 under bhyve with UEFI (edk2-bhyve) on an Intel Xeon E3 host (Hetzner EX44). Without patch: Assertion failed: (error == 0), function modify_bar_registration, file pci_emul.c, line 706. Abort trap. With patch: 9front boots successfully, VNC framebuffer works at 800x600, drawterm connects via cpu server. Patch: --- a/usr.sbin/bhyve/pci_fbuf.c +++ b/usr.sbin/bhyve/pci_fbuf.c -#define FB_SIZE (32*MB) +#define FB_SIZE (16*MB) -#define COLS_MAX 3840 -#define ROWS_MAX 2160 +#define COLS_MAX 1920 +#define ROWS_MAX 1200 The 32MB framebuffer window conflicts with available PCI address space on certain hardware configurations. 16MB works great for 9front specifically. -- You are receiving this mail because: You are the assignee for the bug.home | help
