Fwd: [PATCHv2 0/5] coupled cpuidle state support
Andy, TI seems to be happy with the cpuidle driver based on Colin's couple C-state work. Santosh has provided a branch at the end of this message that is rebased on top of 3.4-rc2. Can we fold this into the TILT tree for April? Daniel, You should provided a consolidated version of your fixes and cleanups to the various LTs too. /Amit -- Forwarded message -- From: Santosh Shilimkar santosh.shilim...@ti.com Date: Mon, Apr 9, 2012 at 10:11 AM Subject: Re: [PATCHv2 0/5] coupled cpuidle state support To: Colin Cross ccr...@android.com Cc: linux-ker...@vger.kernel.org, linux-arm-ker...@lists.infradead.org, linux...@lists.linux-foundation.org, Kevin Hilman khil...@ti.com, Len Brown len.br...@intel.com, Trinabh Gupta g.trin...@gmail.com, Arjan van de Ven ar...@linux.intel.com, Deepthi Dharwar deep...@linux.vnet.ibm.com, Greg Kroah-Hartman gre...@suse.de, Kay Sievers kay.siev...@vrfy.org, Daniel Lezcano daniel.lezc...@linaro.org, Amit Kucheria amit.kuche...@linaro.org, Lorenzo Pieralisi lorenzo.pieral...@arm.com, Rob Lee rob@linaro.org On Friday 30 March 2012 06:23 PM, Santosh Shilimkar wrote: Colin, On Friday 16 March 2012 05:07 AM, Colin Cross wrote: On Wed, Mar 14, 2012 at 11:29 AM, Colin Cross ccr...@android.com wrote: [...] v2: * removed the coupled lock, replacing it with atomic counters * added a check for outstanding pokes before beginning the final transition to avoid extra wakeups * made the cpuidle_coupled struct completely private * fixed kerneldoc comment formatting * added a patch with a helper function for resynchronizing cpus after aborting idle * added a patch (not for merging) to add trace events for verification and performance testing I forgot to mention, this patch series is on v3.3-rc7, and will conflict with the cpuidle timekeeping patches. If those go in first (which is likely), I will rework this series on top of it. I left it on v3.3-rc7 now to make testing easier. I have re-based your series against Len Browns next branch [1] which has time keeping and other cpuidle patches. Have also folded the CPU hotplug fix which I posted in the original coupled idle patch. As you know, we have been playing around this series for OMAP for last few weeks. This version series seems to work as intended and found it pretty stable in my testing. Apart from the cpu hotplug fix and the trace event comment, series looks fine to me.

Re: [RFC] Scheduler recorder and playback
Hi Dmitry,
I use a somewhat older compiler that doesn't whine so much, so I don't
see those warnings (don't get me started on how annoying gcc is lately).
Sent me a compile log and I'll fix them.

Why would you use anything other than the kick-ass ARM toolchain that
Linaro is providing for over a year now? ;-)

Click on view package details link which at the beginning of the package list, right. This is OK! Click to expand Linaro-meta. Download the .dsc and the tar.gz file for linaro-meta.

ARM porting jam on Wednesday
Dear ARM fans, Linaro Developer Platform team organises every week an ARM porting Jam. Next one will be on Wednesday 11th April (we moved from Friday cause weekend does not help in remembering which patches are still to send upstream). The idea is to gather all developers together to fix user space portability issues across the board. There are several things to work on: - the list of bugs being worked on is at launchpad [1] with more useful web interface at [2] 1. https://bugs.launchpad.net/ubuntu/+bugs?field.tag=arm-porting-queueorderby;=-id 2. http://people.linaro.org/~rsalveti/arm-porting-queue/arm-porting-queue-report.html - list from 'make multiarch cross-building work' process which is described at [3][4] with logfiles available at [5] - now that the release is close non-trivial fixes should rather go into Debian than Ubuntu. As this is cross compiler related you do not even have to use ARM devices. 3. http://wiki.linaro.org/Platform/DevPlatform/CrossCompile/MultiarchCrossBuildStatus 4. http://wiki.debian.org/Multiarch/CrossDependencies 5. http://people.linaro.org/~wookey/buildd/precise/sbuild-ma/status.html - You can also help with libffi related issues if you can - list is available at Debian wiki [6] 6. http://wiki.debian.org/ArmHardFloatTodo#libffi Interested in making the software in Ubuntu run better on ARM?

Right, LT kernels work fine with DT boot, we have done DT boot on OMAP4
since last Autumn. We still need to add at least this for a long time

I don't know if that's all that's required.
Last week we tried v3.3 mainline and it dies in some problem about UART.
Omar, you should look here
http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=summary
use tilt-tracking and omap_5430evm_defconfig
That's workable on 4430, 4460 (and Omap5) with DT boot. We have a race
bug about mmc probe outstanding but we can't reproduce it at the moment.
Otherwise for 4460 it should be running on all cylinders.

I'm fairly new to DT and I'm trying to boot it with pandaboard and
k3.3, however above hunk deletes omap serial initialization, which
causes a panic on boot, because pdata is NULL:
static void serial_omap_start_tx(struct uart_port *port)
{
...
if (pdata-set_noidle)
Perhaps because this change skips the following path:
omap_serial_init-omap_serial_board_init-omap_serial_init_port
Where pdata is built in omap_device_build.
I'm just trying to confirm that I'm not alone or doing some silly
thing before getting in depth with the code.
Here it is the panic:

Last time I looked, at v3.3 since that's where we're stuck right now,
dts for Panda is still really minimal. But all over the kernel, there's
dt stuff gone in that's not getting tested even with DT boot path. If
it didn't happen inbetweentimes it might be worth trying at the same
time to generate a maximum dts that exercises the new goodies.
I don't know if that's all that's required.
Last week we tried v3.3 mainline and it dies in some problem about UART.
Have you tried 3.4-rc kernels?
No. Normally I would have rebased immediately but as I explained in
another post, we are camped at v3.3 until our new contributors make it
to the 3.4-rc1 rendezvous point. Since just the -core and -pm topics
are already 650 patches, and it's 1400 total, making a throwaway test
rebase when there's other things still to do is too expensive.
Omar, you should look here
http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=summary
use tilt-tracking and omap_5430evm_defconfig
That's workable on 4430, 4460 (and Omap5) with DT boot. We have a race
bug about mmc probe outstanding but we can't reproduce it at the moment.
Otherwise for 4460 it should be running on all cylinders.
Can someone on the LT, working with Omar, take some time to dig into what all
is needed to boot mainline with DT support? I'm a little surprised
too that it doesn't
just work out of the box. :/
Jassi already took a look last week at v3.3 DT status when he generated
a minimal config for mainline LAVA tests for Andrey.
Jassi maybe you can give pure mainline 3.4-rc1 or HEAD a go and identify
what needs sorting for DT boot path.

AFAIK, Amit Pundir is the ARM LT POC on the android team side and the main reason getting him the board was for that and not for testing. Yes that was the plan but I was mainly doing weekly/monthly testing only, so Zach asked me to forward VE Board to Abhishek for daily/weekly tip testing. So currently VE board is with Abhishek. Regards, Amit Pundir Jon: I am sure if you talk to Amit you can strike a deal with him to help you out on the weekly testing (e.g. every other week). -- Alexander Sack Technical Director, Linaro Platform Teams http://www.linaro.org | Open source software for ARM SoCs http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog ___ linaro-android mailing list linaro-andr...@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-android ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
