booting from floppy hangs in pure64 #125

Open effbiae opened 2 days ago

effbiae commented 2 days ago

with this makefile:

# set b to the path to the BareMetal-OS directory
b=../BareMetal-OS
B=$(shell readlink -f $b)
y=$B/sys

qemu: floppy.img
        qemu-system-x86_64 -machine q35 -m 256 -smp sockets=1,cpus=4 \
                -serial stdio \
                -drive format=raw,file="floppy.img",index=0,if=floppy 

floppy.img:
        cd $B && ./baremetal.sh build
        dd if=/dev/zero of=floppy.img count=2880 bs=512
        cat $y/bios-floppy.sys $y/pure64-bios.sys $y/kernel.sys $y/monitor.bin | \
                dd of=floppy.img conv=notrunc

when i run make, baremetal hangs in pure64 note output to terminal from serial is:


[ Pure64 ]
boot bios
pml4 ok
acpi ok
bsp ok
pic ok
smp ok
kernel start

It happens because of the floppy driver only in QEMU. That's what Ian and I noticed. It works great on real machine & BOCHS

If you are already using QEMU then don't use floppy image but baremetal_os.img

Here is the bochs config file that works for Ian and me bo_flo.cfg.zip

bochs -f bo_flo.cfg -q

effbiae commented 1 day ago

thanks for your feedback, isoux

has an issue been raised with qemu?

when i run bochs with

bochs -f /dev/null -q 'boot:a' 'floppya: 1_44=floppy.img, status=inserted'

it also hangs in pure64

i had to edit your config to run on my system but it still hangs

full log showing hang in pure64:

Not at all, Jack.

has an issue been raised with qemu?

I don't think so, Ian just told me it doesn't work on QEMU. With me, the QEMU freezes when it starts reading the floppy, but not before.

I Tried again and everything works on real machine and bochs (2.8). Try running the ./baremetal.sh setup; ...build; ...install; ...demos. I don't have time right now to really look at your make file and bosh output, but if you don't succeed following Ian's sh script then wait for Ian to answer you.

p.s. If you disable the ata0 disk (in bosh config), then it can cause problems because somewhere in the code is hard coded init of HD.

i ran with this config and got a hang, too.

I did some browsing...

I try your Makefile

<...>
cat $y/bios-floppy.sys $y/pure64-bios.sys $y/kernel.sys $y/monitor.bin | \
                 dd of=floppy.img conv=notrunc

1. You must add one line more at end: dd if=$y/bmfs-lite.img of=floppy.img bs=1024 seek=64 conv=notrunc

2. QEMU work but very very slow about 5 - 10 min (strange) to load floppy. This is reason you view freezing at kernel start/ After that it still do not working (You only see cli) because of init_HD func at Pure64 (or You must add switch to qemu for proper HD image)

  1. BOCH on my present system from (apt install bochs is 2.7) and work as your = with error, but on another system I did compiling bochs 2.8 and works well! I try image than your make produced!

If you want, I can create a branch on my repo where I will speed up the floppy for QEMU and turn off the initialization for HD, so you can try it on QEMU? By the time I realized all this, I was tired. At least for me on a real machine with a real floppy drive everything works great also with BOCHS 2.8

effbiae commented 1 day ago

I don't want to push you when you're tired. I just want a fast way to build an image and run an app... I'll look harder at building a hard disk image

IanSeyler commented 1 day ago

I’ll take a look at this tomorrow.

effbiae commented 1 day ago

hi ian,

this issue isn't important for me any more. i now create a hard disk image for qemu and bochs.

please checkout https://github.com/effbiae/thebug for the pressing issue
