[ACTIVITY] (Linus Walleij) 2012-04-10 - 2012-04-13

by Linus Walleij

== Linus Walleij linusw == === Highlights === * I got Linux v3.4-rc2 to boot on Snowball and HREF500 after submitting a bunch of patches fixing some boot problems. Now I have a testbed for doing pinctrl on ux500. * Applied a bunch of pinctrl patches, full migration of Tegra to pinctrl and bug fixes from Dong Aisheng. * Finalized U9540 basic support patch on top the -rc2 tag for v3.5. * Looked at some NO_IRQ removal issues and irq_domain migration for the FPGA IRQ controller in the ARM Integrator and Versatile. Cooking a patch after some review from Russell. * Discussing power domain issues. * Booked and confirmed tickets to Connect 2.12 in Hong Kong. === Plans === * Send pinctrl fixes to Torvalds. * Send ux500 fixes to ARM SoC. * Review incoming pinctrl patches. * Convert ux500 (gpio-nomadik) to pinctrl for the kernel 3.5 timeframe. * 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 - the HWMON stuff. * Presentation for a dept. here about the platform perimeter from the ESC two weeks ago. Seems useful for getting some news in v3.4+. === Issues === * N/A Thanks, Linus Walleij

[Activity] (Omar Ramirez) Apr 2 - Apr 8

by Omar Ramirez Luna

== Omar Ramirez <omarrmz> == === Highlights === * Working on device tree for mailbox: Find a kernel that works with DT for pandaboard (OMAP4): - k3.4-rc1 doesn't recognize DT blob, k3.3 DT panics at boot. - DT has to be appended to zImage. Find a DT uboot: - secretlab.ca uboot doesn't have usb support for panda, having problems with fatload and mmc. - linaro uboot has problems recognizing dt blob in memory (bootm ${kern} - ${dtb}; doesn't work properly). * Sent "round 2" patches for the agitator, now merged. === Planned === * debugfs interface for big.LITTLE to know which cluster is being used. * Add independent thread switching to the agitator.

[PATCH 0/3] vmevent: Some fixes + a new event type

by Anton Vorontsov

Hi all, This small patch set fixes a bug in the vmevent core, plus makes the vmevent-test buildable w/o unneded SDL library. Plus, we add a new 'cross' event type: the event will trigger whenever a value crosses a user-specified threshold. It works two-way, i.e. when a value crosses the threshold from a lesser values side to a greater values side, and vice versa. We use the event type in an userspace low-memory killer: we get a notification when memory becomes low, so we start freeing memory by killing unneeded processes, and we get notification when memory hits the threshold from another side, so we know that we freed enough of memory. The patches are against git://github.com/penberg/linux.git vmevent/core Thanks! -- Anton Vorontsov Email: cbouatmailru(a)gmail.com
