[TCP]: Appropriate Byte Count support

This is an updated version of the RFC3465 ABC patch originally
for Linux 2.6.11-rc4 by Yee-Ting Li. ABC is a way of counting
bytes ack'd rather than packets when updating congestion control.

The orignal ABC described in the RFC applied to a Reno style
algorithm. For advanced congestion control there is little
change after leaving slow start.

[TCP]: fix congestion window update when using TSO deferal

TCP peformance with TSO over networks with delay is awful.
On a 100Mbit link with 150ms delay, we get 4Mbits/sec with TSO and
50Mbits/sec without TSO.

The problem is with TSO, we intentionally do not keep the maximum
number of packets in flight to fill the window, we hold out to until
we can send a MSS chunk. But, we also don't update the congestion window
unless we have filled, as per RFC2861.

This patch replaces the check for the congestion window being full
with something smarter that accounts for TSO.

13 years ago[PATCH] PCI: fix for Toshiba ohci1394 quirk
Jesse Barnes [Wed, 9 Nov 2005 04:13:02 +0000]
[PATCH] PCI: fix for Toshiba ohci1394 quirk

After much testing and agony, I've discovered that my previous ohci1394
quirk for Toshiba laptops is not 100% reliable.  It apparently fails to
do the interrupt line change either correctly or in time, since in about
2 out of 5 boots, the kernel's irqdebug code will *still* disable irq 11
when the ohci1394 driver is loaded (at pci_enable_device time I think).

This patch switches things around a little in the workaround.  First, it
removes the mdelay.  I didn't see a need for it and my testing has shown
that it's not necessary for the quirk to work.

Secondly, instead of trying to change the interrupt line to what ACPI
tells us it should be, this patch makes the quirk use the value in the
PCI_INTERRUPT_LINE register.  On this laptop at least, that seems to be
the right thing to do, though additional testing on other laptops and/or
with actual firewire devices would be appreciated.

[PATCH] PCI: Change MSI to use physical delivery mode always

MSI hardcoded delivery mode to use logical delivery mode. Recently
x86_64 moved to use physical mode addressing to support physflat mode.
With this mode enabled noticed that my eth with MSI werent working.

msi_address_init()  was hardcoded to use logical mode for i386 and x86_64.
So when we switch to use physical mode, things stopped working.

Since anyway we dont use lowest priority delivery with MSI, its always
directed to just a single CPU. Its safe  and simpler to use
physical mode always, even when we use logical delivery mode for IPI's
or other ioapic RTE's.

[PATCH] pciehp: clean-up how we request control of hotplug hardware

This patch further tweaks how we request control of hotplug
controller hardware from BIOS. We first search the ACPI namespace
corresponding to a specific hotplug controller looking for an
_OSC or OSHP method. On failure, we successively move to the
ACPI parent object, till we hit the highest level host bridge
in the hierarchy. This allows for different types of BIOS's
which place the _OSC/OSHP methods at various places in the acpi
namespace, while still not encroaching on the namespace of
some other root level host bridge.

This patch also introduces a new load time option (pciehp_force)
that allows us to bypass all _OSC/OSHP checking. Not supporting
these methods seems to be be the most common ACPI firmware problem
we've run into. This will still _not_ allow the pciehp driver to
work correctly if the BIOS really doesn't support pciehp (i.e. if
it doesn't generate a hotplug interrupt). Use this option with
caution.  Some BIOS's may deliberately not build any _OSC/OSHP
methods to make sure it retains control the hotplug hardware.
Using the pciehp_force parameter for such systems can lead to
two separate entities trying to control the same hardware.

all host bridges. This allows us to gain control of each hotplug

Reduce the PCI Express hotplug driver's dependence on ACPI.
We don't walk the acpi namespace anymore to build a list of
bridges and devices. We go to ACPI only to run the _OSC or

method to get hotplug device parameters like cache line size,
latency timer and SERR/PERR enable from BIOS.

Note that one of the side effects of this patch is that pciehp
does not automatically enable the hot-added device or its DMA
bus mastering capability now. It expects the device driver to

[PATCH] PCI: add pci_find_next_capability()

Some devices have more than one capability of the same type.  For
example, the PCI header for the PathScale InfiniPath looks like:

04:01.0 InfiniBand: Unknown device 1fc1:000d (rev 02)
Subsystem: Unknown device 1fc1:000d
Flags: bus master, fast devsel, latency 0, IRQ 193
Memory at fea00000 (64-bit, non-prefetchable) [size=2M]
Capabilities: [c0] HyperTransport: Slave or Primary Interface
Capabilities: [f8] HyperTransport: Interrupt Discovery and Configuration

There are _two_ HyperTransport capabilities, and the PathScale driver
wants to look at both of them.

The current pci_find_capability() API doesn't work for this, since it
only allows us to get to the first capability of a given type.  The
patch below introduces a new pci_find_next_capability(), which can be
used in a loop like

for (pos = pci_find_capability(pdev, <ID>);
     pos;
     pos = pci_find_next_capability(pdev, pos, <ID>)) {

13 years ago[PATCH] kbuild: build breaks after -imacros was introduced
Zachary Amsden [Mon, 7 Nov 2005 23:27:51 +0000]
[PATCH] kbuild: build breaks after -imacros was introduced

I have to revert the recent addition of -imacros to the Makefile to get my
tool chain to build.  Without the change, below, I get:

Note that this looks entirely like a toolchain bug.  Here is the offending command:

[pid 12163] execve("/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", ["/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0", "-lang-asm", "-nostdinc", "-Iinclude", "-Iinclude/asm-i386/mach-default", "-D__GNUC__=3", "-D__GNUC_MINOR__=2", "-D__GNUC_PATCHLEVEL__=2", "-D__GXX_ABI_VERSION=102", "-D__ELF__", "-Dunix", "-D__gnu_linux__", "-Dlinux", "-D__ELF__", "-D__unix__", "-D__gnu_linux__", "-D__linux__", "-D__unix", "-D__linux", "-Asystem=posix", "-D__NO_INLINE__", "-D__STDC_HOSTED__=1", "-Acpu=i386", "-Amachine=i386", "-Di386", "-D__i386", "-D__i386__", "-D__tune_i386__", "-D__KERNEL__", "-D__ASSEMBLY__", "-isystem", "/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/include", "-imacros", "include/linux/autoconf.h", "-MD", "arch/i386/kernel/.entry.o.d", "arch/i386/kernel/entry.S", "-o", "/tmp/ccOlsFJR.s"]

Which should execute properly, I think.  But it does not:

zach-dev:linux-2.6.14-zach-work $ make
  CHK     include/linux/version.h
  CHK     include/linux/compile.h
  CHK     usr/initramfs_list
  AS      arch/i386/kernel/entry.o
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/tradcpp0: output filename specified twice
make[1]: *** [arch/i386/kernel/entry.o] Error 1
make: *** [arch/i386/kernel] Error 2

gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

Deprecating the -imacros fixes the build for me.  It does not appear to be a
simple argument overflow problem in trapcpp0, since deprecating all the defines
reproduces the problem as well.  Also, switching -imacros to -include fixes the
problem.

[ARM] 3096/1: Add SharpSL Zaurus power and battery management core driver

Patch from Richard Purdie

This patch adds a power and battery management core driver which with
the addition of the right device files, supports the c7x0 and cxx00
series of Sharp Zaurus handhelds.

The driver is complex for several reasons. Battery charging is manually
monitored and controlled. When suspended, the device needs to
periodically partially resume, check the charging status and then
re-suspend. It does without bothering the higher linux layers as
a full resume and re-suspend is unnecessary. The code is carefully
written to avoid interrupts or calling code outside the module under
these circumstances. It also vets the various wake up sources and
monitors the device's power situation.

Hooks to limit the backlight intensity and to notify the battery
monitoring code of backlight events are connected/added as the
backlight is one of the biggest users of power on the device.

This patch adds support for the LinkSys NSLU2 running with

a cost engineered ARM, XScale 420 based system similar to
the the Intel IXDP425 evaluation board. It uses the
IXP4XX ARCH.

While this patch applies independently of other patches
the resultant kernel requires further patches to successfully
use onboard devices, including the onboard flash. Since these
patches are independent of this one they will be submitted
separately.

A defconfig is not included here because not all of
the required drivers are actually in the kernel.
We intend to provide one as soon as the patches
will be incorporated in mainstream.

Benjamin Herrenschmidt [Thu, 10 Nov 2005 04:04:24 +0000]
[PATCH] ppc64: fix PCI IO mapping

phbs_remap_io(), which maps the PCI IO space into the kernel virtual space,
is called too early on powermac, and thus doesn't work.

This fixes it by removing the call from all platforms and putting it back
into the ppc64 common code where it belongs, after the actual probing of
the bus.

That means that before that call, only the ISA IO space (if any) is mapped,
any PIO access (from quirks for example) will fail. This happens not to be
a problem for now, but we'll have to rework that code if it becomes one in
the future.

If the call to xprt_transmit() fails due to socket buffer space
exhaustion, we do not need to re-encode the RPC message when we
loop back through call_transmit.

Re-encoding can actually end up triggering the WARN_ON() in
call_decode() if we re-encode something like a read() request and
auth->au_rslack has changed.
It can also cause us to increment the RPCSEC_GSS sequence number
beyond the limits of the allowed window.

[PATCH] powerpc: Consolidate asm compatibility macros

This patch consolidates macros used to generate assembly for
compatibility across different CPUs or configs.  A new header,
asm-powerpc/asm-compat.h contains the main compatibility macros.  It
uses some preprocessor magic to make the macros suitable both for use
in .S files, and in inline asm in .c files.  Headers (bitops.h,
uaccess.h, atomic.h, bug.h) which had their own such compatibility
macros are changed to use asm-compat.h.

ppc_asm.h is now for use in .S files *only*, and a #error enforces
that.  As such, we're a lot more careless about namespace pollution
here than in asm-compat.h.

While we're at it, this patch adds a call to the PPC405_ERR77 macro in
futex.h which should have had it already, but didn't.
