Subject: [PATCH 0/2] hw/core: Don't dump incompletely reset cpu
Date: Wed, 27 Aug 2025 15:38:20 +1000 [thread overview]
Message-ID: <20250827053822.4094239-1-richard.henderson@linaro.org> (raw)
The start of CPUState reset.hold happens before any subclasses,
which can result in attempting to dump uninitialized data.
In the case of Sparc, this will SIGSEGV.
