Build sparc32 openbios
by BALARD Arnaud 03 Mar '19

03 Mar '19

Hi, Openbios ! I try to build a bios sparc32 for qemu. I use the script "./config/scripts/switch-arch sparc32" Initializing build tree ok Creating taget config.mak ok Creating taget rules.mak ok Creating config files ok When I do the "make build-verbose" I get the following error : "PATH/openbios/arch/sparc32/context.c: In function 'switch_to': "PATH/openbios/arch/sparc32/context.c:116:5: error: PIC register clobbered by 'l7' in 'asm' Asm_volatile_("\n\tcall_switch_context" ^~~ Rules.mak:219 « target/arch/sparc32/context.o » failed Make[1]: *** [target/arch/sparc32/context.o error 1 Makefile:32 target "subdir-sparc32" failed Make: *** [subdir-sparc32] error 2 I was try to build ppc and sparc64, that's ok, I can boot on my ppc's bios (not on sparc64, I think I need to do another thing). Do you know what I'm doing wrong for sparc 32 ?

[PATCH v2 0/5] SPARC32/SPARC64: allocate and map both kernel and initrd memory
by Mark Cave-Ayland 15 Feb '19

15 Feb '19

Bootloaders such as SILO will have already allocated and mapped the memory for the kernel and initrd before jumping into the kernel, so this patchset does the same for a kernel/initrd loaded directly by QEMU. Otherwise if the kernel/initrd grow beyond the default 1:1 memory region mapped by the PROM then the kernel will panic when clearing the memory on startup. In order for this to work on SPARC32 then the corresponding QEMU patch at https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg06635.html must also be applied.
