[Xen-devel] [PATCH 0/2] Fix Xen boot on XGene



Hi all,

the following commit:

commit 21550029f709072aacf3b90edd574e7d3021b400
Author: Julien Grall <julien.grall@xxxxxxxxxx>

    xen/arm: gic-v2: Automatically detect aliased GIC400


removed PLATFORM_QUIRK_GIC_64K_STRIDE and introduced an heuristic to
check whether the two GICC pages have a 64K stride. However the
heuristic needs device tree to report a GICC region size of 128K to work
properly. That is not the case for some versions of XGene (including the
one I am using, kindly provided by CloudLab.us).

The patch series fixes the issue by reintroducing platform quirks,
PLATFORM_QUIRK_GIC_64K_STRIDE, and forcing GICC size to 128K if
PLATFORM_QUIRK_GIC_64K_STRIDE.

We should consider this series for 4.8.
