https://bugs.launchpad.net/linux-linaro/+bug/709245 - USB Disk IO Slow

by Mounir Bsaibes

This bug was assigned to Mian Yousaf who is no longer working with Linaro. https://bugs.launchpad.net/linux-linaro/+bug/709245 - USB Disk IO Slow Per Andy's last comment: "It seems the issue may be to do with the Panda's hub / ethernet chip idle / wakeup characteristics but since there are no hub registers in there settable from Panda side AFAIK (there are some settable in the missing EEPROM that can configure the hub / Ethernet bridge)" Is there anyone that is willing to handle? Or provide additional insight?

[ACTIVITY] (John Stultz) July 11-15th

by john stultz

=== Highlights === * Chased down some community issues related to long uptime (215 day) crashes and sched_clock. Developed a patch that uses rcu to update sched clock data and avoid multiplication overflows. * Booked plane tickets for Linaro Connect * Contacted Robert Love on his updated ashmem patch and got a feel for his thoughts on upstreaming it. * Continued working on my android alarmtimer test case, and found a few last bugs with my integration with the upstream code. * Sent my current Android alarmtimer integration patches to Arve directly for review. * Updated the Linaro+Android 3.0 branch and pushed it out. * Briefly reviewed and tested amitk's topology patches with Android. === Plans === * Continue working on Android Alarm Timer validation test case & send patches to Arve directly if AOSP license stuff is unresolved. * Get back to Kconfig review/research. === Issues === * AOSP group issue still keeping me from submitting alarmtimer integration patches to AOSP. Hopefully when Patrik gets back next week it can be resolved. * Linaro Connect Hotel is totally booked, working with Arwen on sorting out alternative hotel.

[ACTIVITY] (Dave Martin) week 26 2011 (2011-07-04 - 2011-07-08)

by Dave Martin

== Dave Martin <dmart> == === General Activity === * Some kernel patch work: * CPU info declaration macros -- Addressed Russell's commented and reposted. In Will Deacon's tree, waiting for merge upstream. * Some discussion around VDSO support. Still no clear answer on this. === linaro-kernel-o-standard-arch === * Experimentally merged the ael tree with linux-linaro-2.6.39. Some minor rebasing issues, but finally got something booting on the Cortex-A15 model. === Plans === * Check whether the new kernel trees work in Thumb-2 on mx51evk and follow up with Freescale landing team. * Suggest we disable aligment fixups for linaro images, since gtk-sharp2 is now the only thing known to be affected. === Issues === * Not enough RAM in my development machine for running models :(
