Subject: [PATCH v1 0/1] xen/arm: Disable the Cortex-a53-edac
Date: Thu, 6 Oct 2016 18:36:30 +0200 [thread overview]
Message-ID: <1475771791-9749-1-git-send-email-edgar.iglesias@gmail.com> (raw)
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
The Cortex-A53 EDAC (Error Detection And Correction) Linux driver
uses the implementation defined CPUMERRSR register.
Xen traps but does not yet handle accesses to this reg so dom0 panics
on an undefined instruction at boot.
For Xen-4.8, this patchs disables the A53 EDAC module by removing it from
the device tree.
For Xen-4.9 we may want to allow dom0 to access these regs.
Comments welcome!
Best regards,
Edgar
