Various kernel options are known to interfere with flashrom's attempts to access physical memory through /dev/mem. Some (like CONFIG_STRICT_DEVMEM) are important security measures that cannot be disabled without recompiling the kernel, and are likely to be used more widely over time.
However, complete access to physical memory is unnecessary for some use cases. For example, the SPI interface on an Intel NIC can be accessed by mmapping a BAR resource file in the PCI device directory in sysfs. Has anyone considered implementing such an alternative access method for PCI devices in flashrom?
Hello Ed,
The issue is on our radar but we have not made any plans how to approach it. RFCs, PoCs and Patches very welcome ;)
