Update VBTs

Open crawfxrd opened this issue 1 year ago • 0 comments

The gaze16-3060-b display no longer works pre-OS after this coreboot commit:

  • coreboot/coreboot@4c7e97b26a34: Update fsp submodule to upstream master branch
[DEBUG]  PCI: 00:02.0 init
[INFO ]  GMA: Found VBT in CBFS
[INFO ]  GMA: Found valid VBT in CBFS
[INFO ]  framebuffer_info: bytes_per_line: 4096, bits_per_pixel: 32
[INFO ]                     x_res x y_res: 1024 x 768, size: 3145728 at 0xd0000000
[DEBUG]  PCI: 00:02.0 init finished in 6 msecs

Using the sample VBT allows the display to work again pre-OS.

[DEBUG]  PCI: 00:00:02.0 init
[INFO ]  GMA: Found VBT in CBFS
[INFO ]  GMA: Found valid VBT in CBFS
[INFO ]  framebuffer_info: bytes_per_line: 7680, bits_per_pixel: 32

[DEBUG]  PCI: 00:00:02.0 init finished in 6 msecs

Test:

  • Verify boot splash shows on the display
  • Verify display renders firmware-setup
