so Im hacking at linux kernel, using qemu via virtme. which just runs kernel on the hosts environment. generally things are fine, so thanks for that.
but when I build the graphics driver as module, I cannot allocate for it at modprobe. I searched vmalloc, balloon in qemu.org/doc search, mail-archives, google, and found nothing I recognized as responsive. /usr/bin/qemu-system-x86_64 -fsdev local,id=virtfs1,path=/,security_model=none,readonly,multidevs=remap -device virtio-9p-pci,fsdev=virtfs1,mount_tag=/dev/root -fsdev local,id=virtfs5,path=/usr/local/lib/python3.9/site-packages/virtme-0.1.1-py3.9.egg/virtme/guest,security_model=none,readonly,multidevs=remap -device virtio-9p-pci,fsdev=virtfs5,mount_tag=virtme.guesttools -machine accel=kvm:tcg -watchdog i6300esb -cpu host -parallel none -net none -echr 1 -serial none -chardev stdio,id=console,signal=off,mux=on -serial chardev:console -mon chardev=console -vga none -display none -kernel ./arch/x86/boot/bzImage -append 'virtme_link_mods=/home/jimc/projects/lx/wk-test/builds/v2/.virtme_mods/lib/modules/0.0.0 earlyprintk=serial,ttyS0,115200 console=ttyS0 psmouse.proto=exps "virtme_stty_con=rows 24 cols 154 iutf8" TERM=xterm-256color rootfstype=9p rootflags=version=9p2000.L,trans=virtio,access=any raid=noautodetect ro nokaslr multidevs=remap dynamic_debug.verbose=3 dynamic_debug.dyndbg=+pmf module.dyndbg=+pmf main.dyndbg=+pmf init=/bin/sh -- -c "mount -t tmpfs run /run;mkdir -p /run/virtme/guesttools;/bin/mount -n -t 9p -o ro,version=9p2000.L,trans=virtio,access=any virtme.guesttools /run/virtme/guesttools;exec /run/virtme/guesttools/virtme-init"' -machine dump-guest-core=on bash-5.0# modprobe i915 [ 48.790310] modprobe: vmalloc: allocation failure: 140800168 bytes, mode:0xcc0(GFP_KERNEL), nodemask=(null),cpuset=/,mems_allowed=0 [ 48.792303] CPU: 0 PID: 148 Comm: modprobe Not tainted 5.10.0-rc6-v2-00002-g99821aff738d #61 [ 48.793448] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-3.fc33 04/01/2014 I bet this has been asked before somehow, but I couldnt find it. are there options I can sprinkle in ?
