git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci Pull PCI changes (including maintainer change) from Jesse Barnes: "This pull has some good cleanups from Bjorn and Yinghai, as well as some more code from Yinghai to better handle resource re-allocation when enabled. There's also a new initcall_debug feature from Arjan which will print out quirk timing information to help identify slow quirks for fixing or refinement (Yinghai sent in a few patches to do just that once the new debug code landed). Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas. He's been a core PCI and Linux contributor for some time now, and has kindly volunteered to take over. I just don't feel I have the time for PCI review and work that it deserves lately (I've taken on some other projects), and haven't been as responsive lately as I'd like, so I approached Bjorn asking if he'd like to manage things. He's going to give it a try, and I'm confident he'll do at least as well as I have in keeping the tree managed, patches flowing, and keeping things stable."

2012-02-23mips/PCI: get rid of device resource fixupsBjorn Helgaas
Tell the PCI core about host bridge address translation so it can take care of bus-to-resource conversion for us. Here's the wrinkle on Cobalt: we can't generate normal I/O port addresses on PCI because the GT-64111 doesn't do any address translation, so we have this: CPU I/O port addresses [io 0x0000-0xffffff] PCI bus I/O port addresses [io 0x10000000-0x10ffffff] Legacy-mode IDE controllers start out with the legacy bus addresses, e.g., 0x1f0, assigned by pci_setup_device(). These are outside the range of addresses GT-64111 can generate on PCI, but pcibios_fixup_device_resources() converted them to CPU addresses anyway by adding io_offset. Therefore, we had to pre-adjust them in cobalt_legacy_ide_fixup(). With io_offset = 0xf0000000, we had this: res->start = 0x1f0 initialized in pci_setup_device() res->start = 0x100001f0 -= io_offset in cobalt_legacy_ide_fixup() res->start = 0x1f0 += io_offset in pcibios_fixup_device_resources() The difference after this patch is that the generic pci_bus_to_resource() only adds the offset if the bus address is inside a host bridge window. Since 0x1f0 is not a valid bus address and is not inside any windows, it is unaffected, so we now have this: region->start = 0x1f0 initialized in pci_setup_device() res->start = 0x1f0 no offset by pci_bus_to_resource() That means we can remove both pcibios_fixup_device_resources() and cobalt_legacy_ide_fixup(). I would *rather* set the host bridge offset to zero (which corresponds to what the GT-64111 actually does), and have both CPU and PCI addresses of [io 0x10000000-0x10ffffff]. However, that would require changes to generic code that assumes legacy I/O addresses, such as pic1_io_resource ([io 0x0020-0x00021]), and we'd have to keep a Cobalt IDE fixup. Of course, none of this changes the fact that references to I/O port 0x1f0 actually go to port 0x100001f0, not 0x1f0, on the Cobalt PCI bus. Fortunately the VT82C586 IDE controller only decodes the low 24 address bits, so it does work.

2012-02-23mips/PCI: replace pci_probe_only with pci_flagsBjorn Helgaas
Some architectures (alpha, mips, powerpc) have an arch-specific "pci_probe_only" flag. Others use PCI_PROBE_ONLY in pci_flags for the same purpose. This moves mips to the pci_flags approach so generic code can use the same test across all architectures.

2012-01-11MIPS: Set default pci cache line size.Ralf Baechle
On MIPS the generic PCI code has always defaulted to L1_CACHE_BYTES because the architecutre PCI code did not provide a better default. In particular on systems with S-caches or T-caches this was suboptimal. Provide a better default by setting pci_dfl_cache_line_size based on the size of the line size of the lowest level of the cache hierarchy.

2012-01-06PCI: Pull PCI 'latency timer' setup up into the coreMyron Stowe
The 'latency timer' of PCI devices, both Type 0 and Type 1, is setup in architecture-specific code [see: 'pcibios_set_master()']. There are two approaches being taken by all the architectures - check if the 'latency timer' is currently set between 16 and 255 and if not bring it within bounds, or, do nothing (and then there is the gratuitously different PA-RISC implementation). There is nothing architecture-specific about PCI's 'latency timer' so this patch pulls its setup functionality up into the PCI core by creating a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over-ridden by architecture-specific code.

2011-03-29MIPS: Octeon: Rewrite interrupt handling code.David Daney
This includes conversion to new style irq_chip functions, and correctly enabling/disabling per-CPU interrupts. The hardware interrupt bit to irq number mapping is now done with a flexible map, instead of by bit twiddling the irq number. [ tglx: Adjusted to new irq_cpu_on/offline callbacks and __irq_set_affinity_lock ] Signed-off-by: David Daney <ddaney@caviumnetworks.com> Cc: linux-mips@linux-mips.org Cc: ralf@linux-mips.org LKML-Reference: <1301081931-11240-5-git-send-email-ddaney@caviumnetworks.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2010-10-29MIPS: Octeon: Rewrite DMA mapping functions.David Daney
All Octeon chips can support more than 4GB of RAM. Also due to how Octeon PCI is setup, even some configurations with less than 4GB of RAM will have portions that are not accessible from 32-bit devices. Enable the swiotlb code to handle the cases where a device cannot directly do DMA. This is a complete rewrite of the Octeon DMA mapping code.

2010-10-07MIPS: Add missing #inclusions of <linux/irq.h>David Howells
Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should really include it. Note that this can replace #inclusions of <asm/irq.h>. This is required for the patch to sort out irqflags handling function naming to compile on MIPS. The problem is that these files require access to things like setup_irq() - which isn't available by #including <linux/interrupt.h> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Ralf Baechle <ralf@linux-mips.org>
