Thanks for catching this!

I'd think so.

* [PATCH] powerpc/p3060qds: Fix select of 'MPC8xxx_GPIO'
From: Paul Bolle @ 2011-11-12 23:50 UTC (permalink / raw)
To: Shengzhou Liu, Wolfram Sang
Cc: Anatolij Gustschin, linuxppc-dev, linux-kernel
The driver for the Freescale P3060 QDS got added by commit 96cc017c5b
("[...] Add support for P3060QDS board"). Its Kconfig entry selects
MPC8xxx_GPIO. But at the time that driver got added MPC8xxx_GPIO was
already renamed to GPIO_MPC8XXX, by commit c68308dd50c ("gpio: move
mpc8xxx/512x gpio driver to drivers/gpio").
So make this driver select GPIO_MPC8XXX.

0) Bravely untested: I haven't got the hardware nor the PPC toolchain
needed to build this. And it seems this needs (build) testing anyhow.
1) Sent to the people who wrote the two patches mentioned in the commit
explanation and CC'd the non-authors who signed-off these patches.
2) The config tools do not complain about selects that cannot be met
because they concern a Kconfig symbol that doesn't even exist. Shouldn't
they be made to complain in that case?

* yenta_socket and Machine check in kernel mode

Hi,
The error message "Caused by (from SRR1=214b030): Transfer error ack signal"
is everywhere in my (PowerBook G4) messages.log. I checked, and the module
that cause it is yenta_socket.
That's the messages.log after a rmmod && modprobe (the [...] as for hundred

I'm using the git 3.2.0-rc1 kernel, but I have the same problem with the 2.6.38.
There's something I can do (apart from blacklisting it, and don't use PCMCIA)?
Thanks

* [PATCH 1/5, v3] fsl-rio: Split rio driver into two parts, RapidIO endpoint and message unit
From: Liu Gang @ 2011-11-12 12:02 UTC (permalink / raw)
To: linuxppc-dev, Alexandre.Bounine
Cc: r58472, r61911, linux-kernel, Lian Minghuan, Liu Gang, akpm,
B11780
The Freescale PowerPC RapidIO controller consists of a RapidIO endpoint and
a RapidIO message unit(RMU). Or use RapidIO message manager(RMan) to
replace the RMU in DPAA architecture. Therefore, we should split the code
into two function modules according to the hardware architecture. Add new
struct for RMU module, and new initialization function to set up RMU
module. This policy is very conducive to adding new module like RMan, or
adding multi-ports or message units support.

From: Liu Gang @ 2011-11-12 12:02 UTC (permalink / raw)
To: linuxppc-dev, Alexandre.Bounine
Cc: Jin Qing, r58472, r61911, linux-kernel, Liu Gang, akpm, B11780
In-Reply-To: <1321099352-21462-1-git-send-email-Gang.Liu@freescale.com>
This document is created for powerpc rapidio and rmu nodes in dts file.
These nodes can support two rapidio ports and message units. In addition,
It explicates the properties and gives examples about rapidio and rmu nodes.

+Message unit node:
+
+For SRIO controllers that implement the message unit as part of the controller

+"fsl-srio-dbell-unit" and "fsl-srio-port-write-unit").
+
+See srio.txt for more details about generic SRIO controller details.
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,srio-rmu-vX.Y", "fsl,srio-rmu".
+
+ The version X.Y should match the general SRIO controller's IP Block
+ revision register's Major(X) and Minor (Y) value.
+
+ - reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: A standard property. Specifies the physical address and

+ and doorbell units.
+
+ - fsl,liodn
+ Usage: optional-but-recommended (for devices with PAMU)
+ Value type: <prop-encoded-array>
+ Definition: The logical I/O device number for the PAMU (IOMMU) to be
+ correctly configured for SRIO accesses. The property should
+ not exist on devices that do not support PAMU.
+
+ The LIODN value is associated with all RMU transactions
+ (msg-unit, doorbell, port-write).
+
+Sub-Nodes for RMU: The RMU node is composed of multiple sub-nodes that

+ SRIO port.
+
+ - fsl,liodn
+ Usage: optional-but-recommended (for devices with PAMU)
+ Value type: <prop-encoded-array>
+ Definition: The logical I/O device number for the PAMU (IOMMU) to be
+ correctly configured for SRIO accesses. The property should
+ not exist on devices that do not support PAMU.
+
+ For HW (ie, the P4080) that only supports a LIODN for both
+ memory and maintenance transactions then a single LIODN is
+ represented in the property for both transactions.
+
+ For HW (ie, the P304x/P5020, etc) that supports an LIODN for
+ memory transactions and a unique LIODN for maintenance
+ transactions then a pair of LIODNs are represented in the
+ property. Within the pair, the first element represents the
+ LIODN associated with memory transactions and the second element
+ represents the LIODN associated with maintenance transactions
+ for the port.
+
+Note: All other standard properties (see ePAPR) are allowed but are optional.
+
+Example:
+
+ rapidio: rapidio@ffe0c0000 {
+ #address-cells = <2>;
+ #size-cells = <2>;
+ reg = <0xf 0xfe0c0000 0 0x11000>;
+ compatible = "fsl,srio";
+ interrupts = <16 2 1 11>; /* err_irq */
+ fsl,srio-rmu-handle = <&rmu>;
+ ranges;
+
+ port1 {
+ cell-index = <1>;
+ #address-cells = <2>;
+ #size-cells = <2>;
+ fsl,liodn = <34>;
+ ranges = <0 0 0xc 0x20000000 0 0x10000000>;
+ };
+
+ port2 {
+ cell-index = <2>;
+ #address-cells = <2>;
+ #size-cells = <2>;
+ fsl,liodn = <48>;
+ ranges = <0 0 0xc 0x30000000 0 0x10000000>;
+ };

* [PATCH 2/5, v3] fsl-rio: Add two ports and rapidio message units support
From: Liu Gang @ 2011-11-12 12:02 UTC (permalink / raw)
To: linuxppc-dev, Alexandre.Bounine
Cc: Jin Qing, r58472, r61911, linux-kernel, Liu Gang, akpm, B11780
In-Reply-To: <1321099352-21462-1-git-send-email-Gang.Liu@freescale.com>
Usually, freescale rapidio endpoint can support one or two 1x or 4X
LP-Serial link interfaces, and rapidio message transactions can be
implemented by two message units. This adds the support of two
rapidio ports and initializes message unit 0 and message unit 1. And
these ports and message units can work simultaneously.

Thanks -- not sure why this never showed up in my builds of all the powerpc=
configs, _or_ the linux-next builds. Maybe srio isn't enabled in any of t=
hem?=20
In any case it looks fine to me. Having the search_exception_tables live i=
n module.h seems odd, but that is an independent issue for later.
I can queue this unless someone else has already done so.

Will this code still work on other QE parts, like the MPC8323?

Hi,
QE Microcode Initialization using qe_upload_microcode() does not work on P1=
021 if the IRAM-Ready register is not set after the microcode upload. This =
patch adds a definition for the "I-RAM Ready" register and sets it uppon mi=
crocode upload completion.

Thanks -- not sure why this never showed up in my builds of all the
powerpc configs, _or_ the linux-next builds. Maybe srio isn't enabled
in any of them?
In any case it looks fine to me. Having the search_exception_tables
live in module.h seems odd, but that is an independent issue for later.
I can queue this unless someone else has already done so.
Paul.

* Disabling TCP slow start after idle
From: David Laight @ 2011-11-11 15:30 UTC (permalink / raw)
To: linuxppc-dev, linux-kernel
We have some connections that suffer very badly from the TCP
'slow start' algorithm. These are connections that will
always be local - they may be MAC-Switch-MAC using RGMII
crossover, they might also be connected via an external
switch. In either case the RTT is most likely to be almost
zero, certainly below 1ms.
The traffic is single packets (carrying another protocol)
so we have Nagle disabled and the send and receive sides
run separately. So the traffic is neither bulk, nor
command/response.
This means that there is very rarely any unacked data,
so almost every packet is sent using 'slow start'.
If the external switch drops a packet (they do!) then
slow start stops more packets being sent, and nothing
progresses for about 1.5 seconds by which time there
is a significant amount of traffic queued and, in some
cases, data has to be discarded.
Similar issues happen if the receiving system decides
to defer the ack until a timer tick (instead of
sending one after every second packet). In this case
only 4 packets are sent. (We fixed this one be sending
a software ACK every 4 packets.)
Quite cleary the 'slow start' algorithm just doesn't
work in these cases.
I found this https://lkml.org/lkml/2010/4/9/427
discussion about a socket option to disable slow start.
But it seems that some people are completely against the idea.
I'd have thought that the global option would be more of a
problem - since that will affect ftp connections to remote
hosts where slow start is alomost certainly benefitial.
I'd have thought it would be sensible to allow one (or more)
of the following (either as a sysctl, socket option, or
code change):
1) Disable slow start for the local subnet.
2) Disable slow start for connections with very low RTT.
3) Disable slow start for a minimum period with no traffic
(after the last packet is acked).
I'm not sure of the resolution used by the Linux RTT
calculations. I know NetBSD had a recent set of patches
to fix calculation errors with low RTT because the code
had been written when all RTT were much longer.

That doesn't really answer the question.

Don't you mean defined before they are referenced?
What's wrong with defining them in pre?

* [PATCH] fsl-rio: fix compile error
From: Liu Gang @ 2011-11-11 13:48 UTC (permalink / raw)
To: linuxppc-dev, Alexandre.Bounine
Cc: r58472, linux-kernel, r61911, paul.gortmaker, Liu Gang, akpm,
B11780
The "#include <linux/module.h>" was replaced by "#include <linux/export.h>"
in the patch "powerpc: various straight conversions from module.h --> export.h".
This will cause the following compile problem:
arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_mcheck_exception':
arch/powerpc/sysdev/fsl_rio.c:296: error: implicit declaration of function 'search_exception_tables'.
The file fsl_rio.c needs the declaration of function "search_exception_tables"
in the header file "linux/module.h".

I have been unable to convince our BSP teams that the minor performance=20
improvement of a 32-bit kernel vs 36-bit is not worth the hassle. We ship=
=20
a lot of lower-end e500 systems that will never have more than 2GB of memor=
y.
The P1022DS is an example. We ship 32-bit and 36-bit versions of U-Boot,=20
the kernel, and the device tree. I recently added code to U-boot to=20
detect if you have a mismatched U-Boot and device tree, because it is so=20
easy to mess that up. I would like nothing more than to abandon 32-bit=20
for all e500, but I don't see Freescale allowing that any time soon.
