sh: pci: Support root complex config accesses on SH7786 PCIe. · 2c65d75e

Paul Mundt authored Sep 20, 2010

The SH7786 PCIe is presently unable to enumerate itself in root complex
mode, and has no visibility through either type 0 or type 1 accesses,
despite having a mostly sensible extended config space for each port.
Attempts to generate type 0 or type 1 config cycles result in completer
aborts, so we're ultimately forced to use SuperHyway transactions
instead.

As each port has a single port <-> device mapping that resolves for any
PCI_SLOT definition, we simply hijack devfn 0 for the SuperHyway
transaction and bump up the devfn limit.

With enumeration of the root complex now possible, we also need to insert
an early fixup to hide the BARs from the kernel. With all of that done,
it's now possible to use the pcieport services with all of the PCIe
ports, which is the first step to power management support.

sh: pci: Move Renesas PCI IDs to a better place. · cabdf8bf

Paul Mundt authored Sep 20, 2010

Previously these IDs were only used by one driver, so there was not much
need for having them generically defined. Now that this will no longer
hold true, move them over.

sh: pci: Give SH7786 PHY some time to settle. · 81df84f4

Paul Mundt authored Sep 19, 2010

The spec suggests waiting up to 500ms for the PHY to settle before
testing link state, but practice shows that 100ms is sufficient (this is
the delay value we also use on the other SH-4A PCI controllers, too).
This makes device detection much more reliable, although in the future it
should be a bit faster to simply serialize with a TLP IRQ.

usb: Fix up r8a66597-hcd section mismatches. · 0238a0d8

Paul Mundt authored Sep 16, 2010

The _remove() routine is flagged __init_or_module, despite only being
used in a __devexit context. As the rest of the driver is already
balanced out with __devinit, switch to __devexit and __devexit_p()
wrapping.

sh: Provide a non-multiplexed sys_recvmmsg path. · 51d149be

Paul Mundt authored Sep 14, 2010

Now that the rest of the socket calls are provided through their own
paths, do the same for sys_recvmmsg. It's unlikely we'll ever be able to
kill off the socketcall path, but this at least permits userspace to
gradually begin migrating.

sh: Add syscall entries for non multiplexed socket calls · 459ebb34

Carmelo AMOROSO authored Sep 01, 2010

Linux kernel already has socket syscalls that can be invoked
without the multiplexing sys_socketcall wrapper.
C library wrappers are ready to use them directly. It needs just
to define the missing syscall numbers and provide the related entries
into the syscalls table, like sh64 aleady does.

sh: Set CONFIG_SYSFS_DEPRECATED_V2=n · 248bc0d9

Matt Fleming authored Aug 21, 2010

As the help for the config option suggests, this option really shouldn't
be set by default for any recent distribution as it changes the layout
of sysfs. I spotted this while running debian when udev got very
confused by the sysfs layout and failed to create some device nodes.
