Subject: [PATCH V2 00/15] genirq endian fixes; bcm7120/brcmstb IRQ updates
Date: Wed, 29 Oct 2014 19:17:53 -0700 [thread overview]
Message-ID: <1414635488-14137-1-git-send-email-cernekee@gmail.com> (raw)
I don't know if this will make everyone 100% happy but hopefully we're
inching slightly closer to a solution...
V1->V2:
- Rework big endian support per the discussion on the list
- Get rid of the global compile-time irq_reg_{readl,writel} accessors
and make them private to generic-chip.c, so that on multiplatform
kernels, different irqchip drivers can specify different MMIO behavior
- Rebase on Linus's head of tree
Patch 06/15 still feels a bit like premature optimization to me. Perhaps
we can drop it if nobody reports a measurable performance advantage in
any known configuration?
Kevin Cernekee (15):
irqchip: Replace irq_reg_{readl,writel} with {readl,writel}
sh: Eliminate unused irq_reg_{readl,writel} accessors
genirq: Generic chip: Move irq_reg_{readl,writel} accessors into
generic-chip.c
genirq: Generic chip: Change irq_reg_{readl,writel} arguments
genirq: Generic chip: Add big endian I/O accessors
genirq: Generic chip: Optimize for fixed-endian systems
irqchip: brcmstb-l2: Eliminate dependency on ARM code
irqchip: bcm7120-l2: Eliminate bad IRQ check
irqchip: Remove ARM dependency for bcm7120-l2 and brcmstb-l2
irqchip: bcm7120-l2: Make sure all register accesses use base+offset
irqchip: bcm7120-l2: Fix missing nibble in gc->unused mask
irqchip: bcm7120-l2: Use gc->mask_cache to simplify suspend/resume
functions
irqchip: bcm7120-l2: Extend driver to support 64+ bit controllers
irqchip: Decouple bcm7120-l2 from brcmstb-l2
irqchip: bcm7120-l2: Enable big endian register accesses on BE kernels
