Subject: [Patch v4 5/5] hw/ppc: Pass errp to load_image_targphys() and report errors
Date: Fri, 17 Oct 2025 23:54:27 +0530 [thread overview]
Message-ID: <20251017182426.1423403-2-vishalc@linux.ibm.com> (raw)
In-Reply-To: <20251017181250.1421446-2-vishalc@linux.ibm.com>
Pass errp to load_image_targphys() calls in ppc machine initialization
to capture detailed error information when loading firmware, kernel,
and initrd images.
Use error_reportf_err() instead of error_report() to print the
underlying error details along with context about which image failed
to load.
