Hi everyone,
This Thursday is a public holiday in Germany, so I won't be online and
Deepak is travelling, so let's cancel this weeks meeting. If something
important comes up, you can normally find me on #linaro-storage anyway
or send an email.
I think we can still do the meeting next week as a final preparation
for Connect, but it will likely be a short meeting since we are about
to meet (most of us) in person soon after that.
Arnd
=== Venkatraman S <svenkatr> ===
=== Highlights ===
* Submitted eMMC HPI patch v2 with complete changes upto OMAP controller driver
* Review eMMC BKOPS support and packed CMD support
* Submit various cleanup patches for OMAP MMC
=== Plans ===
* Collect profiling and application responsiveness data for HPI. Check
if the changes
in block layer / elevator can be minimized
* Update etherpad for Linaro connect storage work items, review state
of various features
* Cleanup and send erase block support for elevators to storage domain folks
=== Misc ===
* On leave for 2 days this week (May 15 & 16)
=== Highlights ===
* The mxs-common-clk series was finally pulled into arm-soc
* The late_initcall series was pulled into arm-soc
* Sent a series to convert outstanding imx and mxs device drivers to
adopt pinctrl support based on the dummy state support from Dong
Aisheng. It's on arm-soc now.
* Added device tree support for mxs i2c and audio drivers.
* Fixed various comments people put on mxs device tree branch. With
ack tags from subsystem maintainers collected, requesting Arnd and
Olof to pull the branch for upcoming v3.5 merge window.
* Sent a series to enable audio (DT) support for imx51-babbage and
imx53-qsb board.
* Reviewed and collected various imx device tree patches,
imx6q-sabrelite audio support from Richard Zhao, imx53-qsb DA9053
patch from Paul Liu. Came up the imx/dt/for-3.5 branch which has
been pulled into arm-soc now.
* Sent a couple of patches to update/fix pinctrl-mxs driver.

== Thomas Abraham <thomas-ab> ==
=== Highlights ===
* Reworked the dw-mmc and spi patches based on review comments.
* Adding gpio interrupt and wakeup interrupt support in Samsung pinctrl driver.
=== Plans ===
* Complete the gpio interrupt and wakeup interrupt support in Samsung
pinctrl driver.
* Add device tree support for Samsung pinctrl driver.
== Linus Walleij linusw ==
=== Highlights ===
* Finalized and sent out ux500 pinctrl patches, they're already
ACKed by Stephen from nVidia so I will now funnel this into the
ARM SoC tree. Blueprint updated.
* Most Ux500 patches reported last week have landed in the
ARM SoC tree.
* Helped out in mainlining the ux500 crypto and hash drivers.
Patches are pending in Herbert Xu's tree, with some final touches
around the platform data and variant handling.
* Reviewed the incoming MIPS Lantiq pinctrl driver.
* Reviewed various incoming Ux500 devicetree patches from
Lee Jones.
* Discussed cyclic DMA callback and TX residue semantics with
Russell King, Mark Brown and some ALSA SoC developers.
* Mailed with Hongbo Zhang about DB8500 PRCMU API.
* Noticed incoming patches to siblings of the issue found in the
VIC IRQ handler, paged Julia Lawall about the possibility to
check for this type of bug using coccinelle, she promptly
identified two more suspicious drivers so I sent out patches
for those.
=== Plans ===
* Get Ux500 pinctrl into ARM SoC
* Finalize pinctrl for the upcoming 3.5 merge window.
* Review incoming pinctrl patches.
* Test the PL08x patches on the Ericsson Research
PB11MPCore and submit platform data for using
pl08x DMA on that platform.
* Look into other Ux500 stuff in need of mainlining...
like
- Ux500 clocks (looks like a new assignee might look into this)
- the HWMON stuff.
=== Issues ===
* NONE
Thanks,
Linus Walleij
===== highlights ====
1. Admin Tasks
- Followup for Board shipment
- collected 2 nos, V11 Snowball Board, kernel boots
- Further testing to be carried out
2. Sysadmin
- In the process of getting approval for firewall authentication for
git operations
- complete ubuntu distro setup on Virtual Box
3. DT Tasks
- DT for btemp is almost done, review in process
collected first level review comments from linusw and lee
- Adding platform specific data structure for btemp and to other
ab8500 device components
which helps to build and test the same
4. Support
- spend some time to look into the Uboot DT issue highlighted by
mathieu poirier.
- Supported Raj (newly joined member) for his on boarding activities
===== Plan ====
* Complete new staff tasks
* Continue to code and complete ab8500 DT components
* Review UBoot modification made by mathieu

Hi.
We're using the 3.3 kernel from the TI landing team. The problem we are
facing is with real time audio. We are, through gst-poll, calling poll
every 10th ms to get audio samples. Problem is that it doesn't respond
fast enough, and we only manage to get the samples every 15-30th ms.
We have turned off the 32khz and tickless kernel flags in the kernel,
which seems to have helped some. Problem is that it's not stable at all,
some times it's fast enough, and gives a nice long tone, other times it
have long delays like before.
Do you have any suggestions as to other kernel configs that might help
with this?
Any help would be greatly appreciated.
=== Highlights ===
* Setup ubuntu distro on virtual box. {IT policy does not allow linux
distro on Laptop}
* Completed On Boarding Activities
* Spent time on sysadmin activities to get permission for server
access, distro upgrade etc.,
* Spent some time to look into UBoot DT Issue highlighted by Mathieu Poirier
* DT Study
* Started device tree binding for ab8500 battery temperature sensor.
=== Plans ===
* Complete new staff tasks
* Continue to code and complete ab8500 DT components
* Complete sysadmin activity pending if any
=== Issues ===
SysAdmin activities including Ubuntu distro setup consuming more time.
=== Highlights ===
* Addressed comments people put on arch_initcall cleanup series v1,
and sent out v2 which turns out a pull-request to Arnd for seeking the
exposure on linux-next.
* Reviewed and collected imx pinctrl platform changes from Dong
Aisheng, and sent out a series to add pinctrl support for a number of
outstanding imx and mxs device drivers.
* Sent out a series to have basic imx28 device tree support rebased on
common-clk and pinctrl, and basic imx23 DT support is also added.
* Sent out a series to convert gpio-mxs driver to device tree.
* Sent out a series to convert mxs-mmc driver to device tree.
* Reviewed mxs-dma device tree series v2 from Dong Aisheng and have it
rebased on common-clk and pinctrl.
* Reviewed and collected a few imx6q patches adding UART2 low-level
debug, SPI NOR, and SSI dts changes.
* Helped FSL Landing team enable imx53-qsb audio support on their v3.4 tree.
Regards,
Shawn
