Moblin Kernel and Driver Status for WW51
2.6.24 Kernel Support = Alek continues to port the patches from 2.6.22 to 2.6.24. He is using/referencing the work previously done by Amit. PSB / SLT HW Support Jacob still owes me a patch to work around the MWAIT/local APIC timer issue. We decided to go with the plan to mark the MWAIT instruction broken in the kernel taking out the CPU_FEATURE_MWAIT after cpuid is read for the effected processor. SDIO Feng has released a kernel patch on moblin.org containing Marvell's GPL release of the 8688 WLAN + BT drivers. In the process we've removed the older outdated MSS SDIO kernel patch from moblin.org. Pierre Ossman's SDIO stack is the only choice for SDIO support on moblin. Dabney Thermal patches == No changes this week. USB Client Drivers == Alek continues to add support for the USB Client solution that was described previously. I don't have an update on his status this week. PSB Gfx Video Drivers === Inuka has been investigating a bug with the PSB Gfx Beta3 RC driver where powertop is reporting that X is generating 120+ interrupts/second when the system is idle. This prevents the CPU from going into a lower power C state and blows battery life. The issue is believed to be in the implementation/design on the interface between closed open pieces of the driver. After the holidays we'll be talking directly with the 3rd party developer to get this corrected. Power and Performance Testing/Optimization == Jay has numbers that compares performance between the mobile browser compiled with gcc and browser compiled with Intel C/C++ compiler. As expected there are some significant improvement, for example browser startup appears to be about 25% faster with the version compiled with the Intel compiler. Before we get too excited, we need spend some time scrubbing the data and make sure the numbers we've collected are accurate. +=+=+ Rob Rhoads mailto:[EMAIL PROTECTED] Moblin.org Kernel and Driver Team Lead Open Source Technology CenterOffice: 503-712-6675 Software Solutions Group mobile: 971-533-2451 Intel Corporation Hillsboro, Oregon USA -- Ubuntu-mobile mailing list Ubuntu-mobile@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile

We're looking at total platform memory consumption to see when the target device runs out of physical memory under a specific workload with a certain amount of RAM size. This is done by enabling swap running the workload and recording the number of swaps to disk. Workloads consist of running the web browser or media player.

Moblin Kernel and Driver Status for WW50
2.6.24 Kernel Support = Alek cloned a new kernel repository for holding the 2.6.24 kernel on moblin.org at http://www.moblin.org/repos/develop/linux-2.6.24.git. We're still in our planning for supporting the 2.6.24 kernel, but Alek has started the effort to port our patches to the 2.6.24 kernel. PSB / SLT HW Support Jacob has found that the Local APIC Timer issue is caused by a broken MWAIT instruction in the processor that reveals itself when running tickless idle and entering a C1 state. Jacob is experimenting with a patch to work around the issue. The proper way to handle this issue is to mark the MWAIT instruction as broken to the kernel by taking out the CPU_FEATURE_MWAIT after cpuid is read for the effected processor. This will cause the kernel to use the HALT instruction for the C1 state, but has the more costly side effect for C2 and higher states of replacing MWAIT with an I/O port call and subsequent SM Interrupt and SMI handler in BIOS. SDIO Feng completed integrating porting Marvell's GPL release of the 8688 WLAN + BT drivers to Moblin's 2.6.22 kernel + Pierre's SDIO stack. We're now working through our internal release process for legal compliance so we can release the drivers on moblin.org. Feng also fixed a bug in Pierre's SDIO stack, which is now checked in on moblin.org, that blocked S4 suspend/resume. Dabney Thermal patches == No changes this week. USB Client Drivers == Alek added udev_event support to the USB Client driver so that user-space can be notified when the USB Client port is connected/disconnected. In addition Alek has been committing changes to the crown-beach-config and moblin-image-creator repos for supporting the USB Client implementation that I outlined in last week's status report. PSB Gfx Video Drivers === Inuka completed integration of the PSB Gfx driver Beta3 release and Open Source components have been committed on moblin.org. We added a new repository libva.git on moblin.org to hold the libva package for PSB HW assisted video playback. The closed source components cannot be released on moblin.org due to third-party license restrictions. Power and Performance Testing/Optimization == Jay has been experimenting on using a MID version of the Intel C Compiler with the goal to increase application runtime performance. After several weeks of working with the compiler team we received a version of the compiler that can compile the Mobile Browser and resulting output not core dump. Jay will be running performance tests on the compiler output. Inuka created some scripts that run different workloads and tracks the number of swaps to disk. This is used to gauge our memory consumption while the system is running a specific workload and whether or not we need to tune our SW stack for different memory sizes. If there's interest in these scripts, we can investigate releasing them out on moblin.org. +=+=+ Rob Rhoads mailto:[EMAIL PROTECTED] Moblin.org Kernel and Driver Team Lead Open Source Technology CenterOffice: 503-712-6675 Software Solutions Group mobile: 971-533-2451 Intel Corporation Hillsboro, Oregon USA -- Ubuntu-mobile mailing list Ubuntu-mobile@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile
Moblin Kernel Driver Status
PSB / SLT HW Support Jacob is still root causing the Local APIC Timer issue, this is looking like a potential Si issue with the mwait instruction while in C1 state with Tickless idle enabled. Wakeup events are being ignored. Jacob is working on a workaround for the issue. SDIO We're still in the process of integrating developer testing Marvell's GPL release of the 8688 WLAN + BT drivers. WLAN basic functionality is there, but BT is failing on FTP transfers. Dabney Thermal patches == No changes this week. USB Client Drivers == Alek Du is working on a full USB Client solution for Moblin.org. Specifically he's working on these tasks: * moblin-image-creator will be modified to allow configuring a per-platform vfat partition. Eventually mic will support per-device type configuration, but for now we are just working with per-platform. TODO: determine if per-device configs need to be done in the Moblin Beta3 timeframe. * Alek will add a hotplug script to crown-beach-config that will: - Broadcast a DBus message to notify applications - Attempt to unmount the vfat partition, and if that fails then wait a configurable period of time, kill all processes with open file descriptors on the partition, and then unmount the partion - After the device is disconnected, then mount the vfat partition and then broadcast a DBus message to let applications know that it is Ok to read data off the partition again. This first implementation will not provide a mechanism for the user to cancel the sync operation via the device. That will happen by using the host system to disconnect (or just pulling out the USB cable.) Eventually (and we need to decide if this is a Beta3 thing), we need to have an interactive interface between the applications and the hotplug script to allow an app to prevent a sync. For example, you plug your device into the host system, but only want to charge and wish to continue using the MID. PSB Gfx Video Drivers === We've begun integrating PSB Gfx driver Beta3 release. I'm expecting it to be completed by end of this week. During our integration testing we noticed that With this version of the driver, PowerTop is showing an additional 120 interrupts per second from X. The closed source components will not be released on moblin.org due to third-party license restrictions.

PSB Gfx Drivers and libexa
I took the action item in our weekly meeting to track down what's going on with the Gfx driver and libexa. Here is what I found out... The latest version of the PSB Gfx driver requires that libexa be at v2.2 to support 2-D acceleration. PSB Gfx driver will still work on a system w/ libexa v2.1, but without 2-D acceleration. The problem is that the version of libexa in Gutsy's xorg-xserver-core-1.3 package is v2.1. The developers working on the PSB Gfx driver get around this issue by copying over the version of libexa that the xorg-xserver-core package installs with libexa v2.2. This works for the PSB Gfx driver only and is a hack. It would seem like a better solution would be to update the xorg-xserver-core package to build and install libexa v2.2. The problem with that is that you would need to port and validate all the other X display drivers and other components that have a dependency on libexa. I would expect that to be a lot of work with little gain when we move to Hardy. On Hardy xorg is based on 1.4 and installs v2.2 of libexa. That would seem ideal. Unfortunately the PSB Gfx driver hasn't been developed nor validated against xorg 1.4. It has been developed and validated against xorg 1.3. At this time we're not able to move to xorg 1.4 and will have to investigate for the switch to Hardy. Summary of supported versions: = PSB Gfx driver requirement: libexa v2.2 Base | xorg | xorg-xserver-core | libexa +==+===+ Intel | 1.3 | 1.3 | 2.2 +--+---+ Gutsy | 1.3 | 1.3 | 2.1 +--+---+ Hardy | 1.4 | 1.4 | 2.2 +--+---+ Proposal 1: == For the interim period, while we're on the Ubuntu Mobile PPA code base that is based on Gutsy, we could have the deb package containing the PSB Gfx driver copy over the libexa with v2.2 when it is installed. This way libexa 2.2 would only clobber the previously installed libexa if the PSB Gfx driver is installed. When we move to Hardy, the PSB Gfx driver would be ported to xorg 1.4 and the need for the libexa hack would go away. Proposal 2: == Another idea is to live without 2D acceleration until we switch to Hardy and we move the PSB Gfx driver to xorg 1.4. This is not very desirable from Intel's perspective, because we can't get any test coverage or performance tuning on the driver until we switch to Hardy. I'm leaning towards proposal 1, even though it's far from ideal. Comments? Suggestions? Other ideas? +=+=+ Rob Rhoads mailto:[EMAIL PROTECTED] Software Architect Open Source Technology CenterOffice: 503-712-6675 Software Solutions Group mobile: 971-533-2451 Intel Corporation Hillsboro, Oregon USA -- Ubuntu-mobile mailing list Ubuntu-mobile@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile

The reason I ask is that I've got an engineer who tried this usage scenario using the Tribe 4 CD and the install crashed in the middle. (I'd guess it was because the install CD may not be using the UME kernel which would cause problem on a Crown Beach.) I think we can accommodate his needs for installing full Gutsy on a Menlow system with image-creator, by either providing him with custom FSets (or showing him how to create them) for creating menlow images which will suite his needs. But I wanted to pick the collective brain on this type of usage scenario. +=+=+ Rob Rhoads mailto:[EMAIL PROTECTED] Software Architect Open Source Technology CenterOffice: 503-712-6675 Software Solutions Group mobile: 971-533-2451 Intel Corporation Hillsboro, Oregon USA -- Ubuntu-mobile mailing list Ubuntu-mobile@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile
