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
