[:BuildingCommunity/TeamReporting:Back to the Team Reporting page...]
Welcome to the MobileAndEmbedded reporting page. Every month this page reveals a snapshot of the work that has been going on in the Ubuntu Mobile and Embedded Community. If you have have been working hard on the project and want to let others know what you have been up to, try to summarize it here. Community contributions are actively encouraged. A few guidelines for how to write good points are:
Keep it simple and short - single sentences are best.
- Try to summarise your work and not be over-detailed - we don't need to know specifics, just a summary of the kind
- Where possible, include relevant links.
You should get all your reporting included here by the 22nd of every month.
Status report for week 04
Moblin Kernel and Driver Status
- Kernel Support Alek rebased kernel-mid-2.6.24 to linux-2.6.24-rc8. Alek also fixed the issue - WIFI does not work on Samsung Q1 Ultra. The root cause is Ubuntu kernel uses a volatile tmpfs to hold restricted drivers, while Moblin Image Creator would lose the volatile during umount/mount cycle and thus would create wrong Modules.dep file. PSB / SLT HW Support No changes this week. SDIO Feng successfully ported Marvell SDIO 8686 wifi card V9 version driver (with V9 firmware). The new driver was not put to Moblin yet. We expected lots of tests to verify the new ported driver. Dabney Thermal patches No changes this week. USB Client Drivers Moblin Media team is starting to integrate USBC media sync feature, mainly focus on DBus message handling exported by udev scripts. A driver upgrading was scheduled in WW09.
PSB Gfx & Video Drivers Inuka upgraded PSB Gfx drivers to Beta6. Both kernel drivers and user space drivers were updated. Power and Performance Testing/Optimization Jay tested Moblin kernel-mid 2.6.22 S3 stability on Crown-beach D0 board. Jay found: 1. without nolapic_timer, the system could suspend/resume once, but for second cycle, the system would hang with post code 0200/0002, and system could resume normally after toggling lid switch couple of time. 2. with USB Ethernet dongle, after resume from S3, kernel would have 800+ wake up events per second. Sometimes, with the USB Ethernet dongle the system even refused to suspend to S3. 3. Sometimes USB mouse did not work properly after resume and USB Ethernet dongle could not get IP address. Jay would like to discuss this issue with Ubuntu kernel team during Intel/Ubuntu sprint. Grub fast boot/resume No changes this week.
