Subject: [RFC PATCH 00/11] Add UEFI support for RISC-V
Date: Thu, 25 Jun 2020 16:45:05 -0700 [thread overview]
Message-ID: <20200625234516.31406-1-atish.patra@wdc.com> (raw)
This series adds UEFI support for RISC-V.
Linux kernel: 5.8-rc2
U-Boot: master
OpenSBI: master
Patch 1-6 are preparatory patches that fixes some of the geric efi and riscv issues.
Patch 7-9 adds the efi stub support for RISC-V which was reviewed few months back.
http://lists.infradead.org/pipermail/linux-riscv/2020-April/009586.html
Patch 10 just renames arm-init code so that it can be used across different
architectures. Patch 11 adds the runtime services for RISC-V.
The patches can also be found in following git repo.
https://github.com/atishp04/linux/tree/uefi_riscv_5.9_v1
The patches have been verified on Qemu using bootefi command in U-Boot for both
RV32 and RV64.
For RV32, maximum allocated memory should be 1G as RISC-V kernel can not map
beyond 1G of physical memory for RV32.
EDK2 can boot quite far into Linux with current series. Currently, we are seeing
some traps from drivers (spi/network). At first glance, they don't seem to be
caused by efi. I thought it is better to get some early feedback on the series
while EDK2 issue is being debugged.
That's why uefi runtime services are not actually well tested in RISC-V.
Any suggestions to test the efi run time services are appreciated.
Changes from previous version:
1. Added full ioremap support.
2. Added efi runtime services support.
3. Fixes mm issues
Anup Patel (1):
RISC-V: Move DT mapping outof fixmap
Atish Patra (10):
efi: Fix gcc error around __umoddi3 for 32 bit builds
RISC-V: Setup exception vector early
RISC-V: Add early ioremap support
RISC-V: Set maximum number of mapped pages correctly
riscv: Parse all memory blocks to remove unusable memory
include: pe.h: Add RISC-V related PE definition
RISC-V: Add PE/COFF header for EFI stub
RISC-V: Add EFI stub support.
efi: Rename arm-init to efi-init common for all arch
RISC-V: Add EFI runtime services
