Since this feature is incomplete (see comments in previous versions of this series: $ git grep saarp hw/mips/cps.c:98: saar_present = (bool)env->saarp; target/mips/cpu.h:1103: int saarp; and I don't know how to test this, I'll defer to Aleksandar regarding this patch. > } > object_property_set_bool(OBJECT(&s->itu), true, "realized", &err); > if (err != NULL) { >

Hello, Philippe, Good that you brought this to my attention - but Marc-André and I already had a discussion about this in this series' cover letter responses (unfortunately not followed up by me as a response to this patch, sorry about that): https://lists.gnu.org/archive/html/qemu-devel/2019-12/msg00056.html In essence, our conclusion was that the real fix would be certainly outside of the scope of this series, since it requires some really (non-straightforward) mips-specific code changes, so we agreed that Marc-André submit this patch as-is, and later on (certainly within timeframe of 5.0) I will submit the fix addressing the root cause (absence of "saar" property, and incomplete handling of SAAR and SAARI config registers). In other words, this patch is fine at this moment, and formally: Reviewed-by: Aleksandar Markovic <amarkovic@wavecomp.com> (Marc-André, just please remove "RFC" from the title, and remove the sentence "Note: I haven't been able to test this code. Help welcome." from the commit message, since we have the deal on how and who will fix the underlining problem.) Thanks to both of you! Aleksandar

There is no "saar" property. Note: I haven't been able to test this code. Help welcome.
