[Qemu-devel] [Bug 1679358] Re: ARM: SCTLR fields not being preserved
** Tags added: arm ** Summary changed: - ARM: SCTLR fields not being preserved + ARM: RES0/RES1 SCTLR fields not read-only ** Changed in: qemu Status: New => Confirmed -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1679358 Title: ARM: RES0/RES1 SCTLR fields not read-only Status in QEMU: Confirmed Bug description: There are fields in SCTLR that are RAO/SBOP or WI or in the case of the RR field, accessible only in secure mode. Currently it seems that qemu just propagates any write to SCTLR to the register and this screwed up in a bootloader that I am debugging.

[Qemu-devel] [Bug 1679358] Re: ARM: SCTLR fields not being preserved
Well, I wouldn't object to a patch to fix it (it would have to correctly handle the various different versions of the CPU architecture we implement, etc), but I'm not planning on writing one today myself. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1679358 Title: ARM: SCTLR fields not being preserved Status in QEMU: New Bug description: There are fields in SCTLR that are RAO/SBOP or WI or in the case of the RR field, accessible only in secure mode.

[Qemu-devel] [Bug 1679358] Re: ARM: SCTLR fields not being preserved
So there won't be a fix in the future? I'm working with debugging a proprietary bootloader that I do not have the source code for. I wonder if this becomes an issue for any other platform targets. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1679358 Title: ARM: SCTLR fields not being preserved Status in QEMU: New Bug description: There are fields in SCTLR that are RAO/SBOP or WI or in the case of the RR field, accessible only in secure mode.
