2010-12-14ARM: GIC: move enablement of PPI interrupts to gic.cRussell King1-0/+1
Avoid adding nasty genirq-specific code to local timers to enable PPI interrupts. Instead, provide a gic function to do this. Signed-off-by: Russell King <[email protected]>
2010-12-14ARM: GIC: private a standard get_irqnr_preamble assembler macroRussell King1-0/+7
Provide a standard get_irqnr_preamble assembler macro for platforms to use, which retrieves the base address of the GIC CPU interface from gic_cpu_base_addr. Allow platforms to override this by defining HAVE_GET_IRQNR_PREAMBLE.

2010-12-14ARM: GIC: consolidate gic_cpu_base_addr to common GIC codeRussell King1-0/+2
Every architecture using the GIC has a gic_cpu_base_addr pointer for GIC 0 for their entry assembly code to use to decode the cause of the current interrupt. Move this into the common GIC code.

2010-12-14ARM: GIC: Remove MMIO address from gic_cpu_init, rename to gic_secondary_initRussell King1-1/+1
We don't need to re-pass the base address for the CPU interfaces to the GIC for secondary CPUs, as it will never be different from the boot CPU - and even if it was, we'd overwrite the boot CPU's base address. Get rid of this argument, and rename to gic_secondary_init().

2010-12-14ARM: GIC: provide a single initialization function for boot CPURussell King1-1/+1

2010-12-07ARM: 6475/1: Introduce asm/hardware/entry-macro-gic.SMagnus Damm1-0/+68
This patch is the identical GIC demux implementation merge V3. Instead of implementing same code over and over simply share it in entry-macro-gic.S. The shared code is based on the realview implementation. Each GIC demux instance still has to setup the base address of the controller using the get_irqnr_preamble macro. The rest of the GIC specific code can be shared. Signed-off-by: Magnus Damm <[email protected]> Acked-by: Srinidhi Kasagar <[email protected]> Signed-off-by: Russell King <[email protected]>

PL330 is a configurable DMA controller PrimeCell device. The register map of the device is well defined. The configuration of a particular implementation can be read from the six configuration registers CR0-4,Dn. This patch implements a driver for the specification:- http://infocenter.arm.com/help/topic/com.arm.doc.ddi0424a/DDI0424A_dmac_pl330_r0p0_trm.pdf The exported interface should be sufficient to implement a driver for any DMA API.

The L310 cache controller's interface is almost identical to the L210. One major difference is that the PL310 can have up to 16 ways. This change uses the cache's part ID and the Associativity bits in the AUX_CTRL register to determine the number of ways. Also, this version prints out the CACHE_ID and AUX_CTRL registers.

When we reach the loop, len is at least 1, we only stay in the loop when len is at least MAX_BYTE_COUNT + 1, MAX_BYTE_COUNT is subtracted in each iteration. So when we leave the loop, or didn't take it, len is at least 1. Testing whether len is non-zero appears redundant.

2009-12-02ARM: 5841/1: a driver for on-chip ETM and ETBAlexander Shishkin1-0/+165
This driver implements support for on-chip Embedded Tracing Macrocell and Embedded Trace Buffer. It allows to trigger tracing of kernel execution flow and exporting trace output to userspace via character device and a sysrq combo. Trace output can then be decoded by a fairly simple open source tool [1] which is already sufficient to get the idea of what the kernel is doing.

2009-10-29iop: enable generic timeMikael Pettersson1-1/+0
This updates the IOP platform to use the kernel's generic time framework. With clockevent support in place, this reduces to selecting GENERIC_TIME and removing the platform's private timer ->offset() operation (iop_gettimeoffset). Tested on n2100, compile-tested for all plat-iop machines. Signed-off-by: Mikael Pettersson <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2009-10-29iop: clockevent supportMikael Pettersson1-0/+12
This updates the IOP platform to expose the interrupting timer 0 as a clockevent object. The timer interrupt handler is changed to call the clockevent ->event_handler() instead of timer_tick(), and ->set_next_event() and ->set_mode() operations are added to allow the mode of the timer to be updated (required for ONESHOT/NOHZ mode). Timer 0 must now be properly initialised, which requires a new write_tcr0() function from the mach-specific code. The mode of timer 0 must be read at the start of ->set_mode(), which requires a new read_tmr0() function from the mach- specific code. Initial setup of timer 0 is also rewritten to be more robust. Tested on n2100, compile-tested for all plat-iop machines. Signed-off-by: Mikael Pettersson <[email protected]> Signed-off-by: Dan Williams <[email protected]>
2009-10-29iop: clocksource supportMikael Pettersson1-0/+5
This updates the IOP platform to expose the free-running timer 1 as a clocksource object. This timer is now also properly initialised, which requires a new write_tcr1() function from the mach-specific code. Apart from the explicit initialisation, there is no functional change in how timer 1 is programmed. Tested on n2100, compile-tested for all plat-iop machines.
