[Qemu-devel] [Bug 1409246] Re: ARM GIC / PL061 error on uni-processor system

[Christopher Horler]

now I look further I notice that the pl061_platform_data structures are
not fully initialised in the kernel

linux-3.18.1/arch/arm/mach-realview/realview_pba8.c

so this probably isn't a qemu bug

Title:
  ARM GIC / PL061 error on uni-processor system

Status in QEMU:
  New

Bug description:
  address@hidden:~/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?
