[PATCH 0/2] IRQ-related changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

The following two patches are enabling SPARSE_IRQ
numbering scheme on OMAP. I lightly tested on a pandaboard
and seems to be working fine so far:

# cat /proc/interrupts
           CPU0       CPU1
 39:          1          0         GIC  TWL6030-PIH
 44:       1758          0         GIC  DMA
 69:       7615          0         GIC  gp timer
 88:        195          0         GIC  i2c_omap
 89:          0          0         GIC  i2c_omap
 93:          0          0         GIC  i2c_omap
 94:          0          0         GIC  i2c_omap
102:          0          0         GIC  serial idle
104:          0          0         GIC  serial idle
105:          0          0         GIC  serial idle
106:        743          0         GIC  serial idle, OMAP UART2
115:       2356          0         GIC  mmc0
160:          0          0        GPIO  mmc0
376:          0          0     twl6030  twl4030_pwrbutton
379:          0          0     twl6030  rtc0
IPI:       1111       9537
LOC:          0          0 
Err:          0

The first patch just removes the direct access to irq_desc
array and converts it to irq_to_desc(). Second patch simply
selects HAVE_GENERIC_HARDIRQS and HAVE_SPARSE_IRQ. I boot
tested with and without enabling:

 -> General setup
  -> IRQ subsystem
   -> SPARSE_IRQ

and both kernels boot fine.

Felipe Balbi (2):
  arm: omap: gpio: don't access irq_desc array directly
  arm: omap: select HAVE_SPARSE_IRQ
