Hi, I wanted to directly sent the qemu binaries for test, but it
seems too big, so I attach the patch for qemu about the feature, to
help validate the seabios patch.
With the patched qemu compiled:
Alternate the bios.bin that qemu used to the patched, put the
logo picture in the pc-bios folder or other place, invoker it as
qemu-system-x86_64 -boot splash_time=<N>,splash_filename=<N>
Time unit is ms. Default splash picture is bootsplash.bmp stored
in the directory where bios.bin stay.
qemu in 32bit mode could be applied also.
jpeg decoder have its limitation, it only accept jpg file with
width=16*N, height=16*N. Strange thing is for some picture it have a
good visual effect, while some with observable quality loss.
bmp decoder only accept 24bpp file, with a resolution that a VESA
mode could support. Recommended is 640x480(mostly used).
It seems the latest qemu code from git have some problem in
compiling and its TCG. If this problem still exist when u get it,
following could solve it:
git reset --hard f44c99607a46484c52f03aed373e3a3a194af721
invoke it with option --enable-kvm, to bypass TCG.
If you get a better method to share the testing binaries, pls let
me know. Feel free to put any comments.
