The AArch32 DBGDIDR defines properties like the number of breakpoints, watchpoints and context-matching comparators. On an AArch64 CPU, the register may not even exist if AArch32 is not supported at EL1. Currently we hard-code use of DBGDIDR to identify the number of breakpoints etc; this works for all our TCG CPUs, but will break if we ever add an AArch64-only CPU. We also have an assert() that the AArch32 and AArch64 registers match, which currently works only by luck for KVM because we don't populate either of these ID registers from the KVM vCPU and so they are both zero. Clean this up so we have functions for finding the number of breakpoints, watchpoints and context comparators which look in the appropriate ID register. This allows us to drop the "check that AArch64 and AArch32 agree on the number of breakpoints etc" asserts: * we no longer look at the AArch32 versions unless that's the right place to be looking * it's valid to have a CPU (eg AArch64-only) where they don't match * we shouldn't have been asserting the validity of ID registers in a codepath used with KVM anyway Backports commit 88ce6c6ee85d902f59dc65afc3ca86b34f02b9ed from qemu |
