Hi Ilias,
I have been testing with grub, and with the efi selftest. Here are the
steps to test with a riscv grub:
1. Get grubriscv64.efi from e.g. the following .deb package
wget http://launchpadlibrarian.net/754414418/grub-efi-riscv64-
unsigned_2.12-5ubuntu5.1_riscv64.deb <http://
launchpadlibrarian.net/754414418/grub-efi-riscv64-
unsigned_2.12-5ubuntu5.1_riscv64.deb>
If you are on Debian or Ubuntu you can use
dpkg -x grub-efi-riscv64-unsigned_2.12-5ubuntu5.1_riscv64.deb target_dir
for extraction.
On other distros
ar -x grub-efi-riscv64-unsigned_2.12-5ubuntu5.1_riscv64.deb
mkdir -p target_dir
tar --zstd -xf data.tar.zst -C target_dir
target_dir/usr/lib/grub/riscv64-efi/monolithic/grubnetriscv64.efi
is the file I am using. That one has all the network modules included.
Best regards
Heinrich
2. Compile U-boot with qemu-riscv64_smode_defconfig. Enable CMD_WGET.
3. Create a tap interface:
$ sudo ip tuntap add dev tap0 mode tap
$ sudo ip addr add 10.0.0.0/24 <http://10.0.0.0/24> dev tap0
$ sudo ip link set dev tap0 up
4. Start an http server in a directory containing grubriscv64.efi and a
test file (e.g. a riscv kernel)
$ sudo python3 -m http.server 80 --bind 10.0.0.0
5. Launch U-boot:
$ qemu-system-riscv64 \
-machine virt \
-nographic \
-kernel u-boot \
-netdev tap,id=net0,ifname=tap0,script=no,downscript=no \
-device virtio-net-device,netdev=net0
6. Inside U-boot's console
=> setenv ipaddr 10.0.0.1
=> setenv netmask 255.255.255.0
=> wget 10.0.0.0:80/grubriscv64.efi <http://10.0.0.0/grubriscv64.efi>
=> bootefi $loadaddr
7. Print debug, check address and installed protocols (optional):
grub> set debug="peimage,net"
grub> net_ls_addr
grub> lsefi
8. Download a test file, e.g. a kernel, through http (here Image is a
riscv linux kernel):
grub> linux (http,10.0.0.0:80)/Image
9. Try boot it:
grub> boot
Best,
Adriano

Add support for EFI_HTTP_PROTOCOL,

This series depends on the series 'wget: Expose wget to

also found at:
https://github.com/0n41rd4/u-boot/commits/http-driver-wget
<https://github.com/0n41rd4/u-boot/commits/http-driver-wget>
The fist two patches of this series are not efi specific and
have also
been sent to the corresponding maintainers, but this series
depends on
them, so they are added here for redundancy. A branch with both
series
of patches, concatenated, is at:
https://github.com/0n41rd4/u-boot/commits/efi-http-driver
<https://github.com/0n41rd4/u-boot/commits/efi-http-driver>
It would help a lot if we had pointers (or an EFI app) using this
protocol to test. Are you using any of that for devel/debugging?
Thanks
