Yes, we're a bit loose in QEMU on the handling of reserved bits. Note that most of the SCTLR bits like this are RAO/SBOP or RAZ/SBZP, so the guest should not be writing wrong values to them. thanks -- PMM
[Qemu-devel] [Bug 1679358] [NEW] ARM: SCTLR fields not being preserved
Public bug reported: 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. ** Affects: qemu Importance: Undecided Status: New -- 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.
