WiP VGA correctness
Status qemu coreboot config: +CONFIG_GENERIC_LINEAR_FRAMEBUFFER=y momentarily qemu linux config: +CONFIG_X86_SYSFB=y seems to be requirement for non legacy VESA bringup, but seems to break Heads?!? removal of vga 16 removal of vesa leaving simplefb NOTE: CONFIG_DRM_FBDEV_EMULATION is required and provides linux console support on top of modesetting driver modules/linux/coreboot: add modify helpers to generate in place oldconfigs and defconfigs WiP: kexec-boot: modifying kexec passed boot options on qemu for Tinycore. A bit confused on why kexec call just freezes there. Next time is investigating how to gdb into qemu for firmware, since we should have output on host console even if qemu is not able to get vga, and vga should be able to be reused from kexec call since: user@heads-tests:/media/boot$ zcat core.gz | cpio -ivt | grep -e vga -e fb -e drm -e virt lrwxrwxrwx 1 root root 17 May 8 2022 usr/sbin/fbset -> ../../bin/busybox drwxr-xr-x 3 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/virt drwxr-xr-x 2 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/virt/lib -rw-r--r-- 1 root root 1779 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/virt/lib/irqbypass.ko.gz -rw-r--r-- 1 root root 4556 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/net/vmw_vsock/vmw_vsock_virtio_transport.ko.gz -rw-r--r-- 1 root root 6898 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/net/vmw_vsock/vmw_vsock_virtio_transport_common.ko.gz drwxr-xr-x 3 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev -rw-r--r-- 1 root root 9612 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/udlfb.ko.gz drwxr-xr-x 2 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/core -rw-r--r-- 1 root root 2149 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/core/sysfillrect.ko.gz -rw-r--r-- 1 root root 1274 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/core/fb_sys_fops.ko.gz -rw-r--r-- 1 root root 1782 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/core/sysimgblt.ko.gz -rw-r--r-- 1 root root 2268 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/core/syscopyarea.ko.gz -rw-r--r-- 1 root root 7035 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/video/fbdev/hyperv_fb.ko.gz -rw-r--r-- 1 root root 3082 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/gpio/gpio-virtio.ko.gz drwxr-xr-x 3 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/drivers/virt drwxr-xr-x 2 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/drivers/virt/vboxguest -rw-r--r-- 1 root root 12506 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virt/vboxguest/vboxguest.ko.gz drwxr-xr-x 2 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/drivers/virtio -rw-r--r-- 1 root root 8029 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_ring.ko.gz -rw-r--r-- 1 root root 3847 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_pci_modern_dev.ko.gz -rw-r--r-- 1 root root 3718 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio.ko.gz -rw-r--r-- 1 root root 7084 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_pci.ko.gz -rw-r--r-- 1 root root 3377 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_input.ko.gz -rw-r--r-- 1 root root 6258 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_balloon.ko.gz -rw-r--r-- 1 root root 1042 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_dma_buf.ko.gz -rw-r--r-- 1 root root 3551 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/virtio/virtio_mmio.ko.gz -rw-r--r-- 1 root root 6916 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/block/virtio_blk.ko.gz -rw-r--r-- 1 root root 17961 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/net/virtio_net.ko.gz drwxr-xr-x 2 root root 0 May 8 2022 lib/modules/5.15.10-tinycore/kernel/drivers/crypto/virtio -rw-r--r-- 1 root root 7020 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/crypto/virtio/virtio_crypto.ko.gz -rw-r--r-- 1 root root 5924 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/iommu/virtio-iommu.ko.gz -rw-r--r-- 1 root root 10007 Dec 21 2021 lib/modules/5.15.10-tinycore/kernel/drivers/char/virtio_console.ko.gz Last line is virtio_console that qemu is using....
