Public bug reported:
chorler@linux-foxtrot:~/projects/src/qemu> git describe
v2.2.0-369-gab0302e
When booting Linux 3.19.1 (default buildroot), configured for realview-
pb-a8 on qemu from git (as above).
The following message appears (line 253/ 254 of attached log):
"GIC CPU mask not found - kernel will fail to boot."
The kernel does boot - so perhaps this is a misleading error message?
(though temporarily tweaking commit 6b9680bb does remove the message)
later the following three lines appear when pl061 is probed (resulting in
ENODEV):
pl061_gpio dev:gpio0: invalid IRQ base in pdata
pl061_gpio dev:gpio1: invalid IRQ base in pdata
pl061_gpio dev:gpio2: invalid IRQ base in pdata
(from linux-3.18.1/drivers/gpio/gpio-pl061.c line 253)
qemu/hw/arm/realview.c
has some code that suggests to me pl061 is required for the MMC.
Where should I look to see how to initialise the irq_base member of the
platform data in QEmu?
