l4 build problem on Intel Atom 330

Hello, I was trying to build L4,L4RE, L4Linux for the Intel atom board. I tried to build everything from the scratch. But I am not able to boot l4linux on intel atom. The same image if I am running on QEMU then it is working. I don't know what I am doing wrong. Pleas Help. The difference that I can see while running on QEMU and Intel Atom is: QEMU: CPU0: AMD QEMU Virtual CPU version 1.0 stepping 03 Performance Events: l4linux | WARNING: Unknown rdmsr: c0010000 at 0x6d529f l4linux | WARNING: Unknown rdmsr: c0010001 at 0x6d529f l4linux | WARNING: Unknown rdmsr: c0010002 at 0x6d529f l4linux | WARNING: Unknown rdmsr: c0010003 at 0x6d529f l4linux | WARNING: Unknown wrmsr: c0010004 at 0x6d531d l4linux | WARNING: Unknown rdmsr: c0010004 at 0x6d532f Broken PMU hardware detected, using software events only.

About Inter-process Communication
by ZhangEditing 24 Jul '12

24 Jul '12

Hello. I need to send megabytes of data from one virtual machine to another. I looked into source code of IPC streams for C++, but did not find any facility for sending the content of a large buffer (say, 512B). I have also noticed the buffer registers in the UTCB, but I haven't figured out how to use it. If there is a way to send the content of a large buffer, would you please reference me to the related documents? A simple example would be very helpful.

SATA AHCI driver head banging.
by Daniel Waddington 23 Jul '12

23 Jul '12

Hi, I am trying to build a SATA driver for our Fiasco.OC personality. The h/w is a Intel 82801J IOCH in a PC platform. I get can pick up the device in the PCI, get BAR5 and map in the control registers. I then initialize the card (into AHCI mode), set up memory (command list and command tables) and try to do an IDENTIFY_DEVICE command. The command issues, and returns a PIO Setup FIS (type 5f). PxTFD.STS.DRQ=1 PxTFD.STS.BSY=0 PxSERR=0 PxSACT=1. The PIO setup FIS indicates a transfer count of 512 bytes (which is correct). All good so far, but then no interrupt happens and no more FISes appear - and I don't know what to do next. The same behavior occurs on another PC platform with a IOCH9 controller. I have not done anything w.r.t. configuring or re-routing IRQs in the PCI subsystem (a black hole to me). Is there something that is a must that I'm clearly missing here?? Any clues, much appreciated. Daniel

Re: l4linux GPU direct access
by Abhishek Gupta 23 Jul '12

23 Jul '12

Hi Adam, My final objective is just to get the graphic acceleration working, so having the gpu initialized by fbdrv is perfectly fine but I can't find a working configuration. What we have are two configs which work well separately (fbdrv and pci direct access) but we didn't understand yet how to combine them. I can see the log messages from fbdrv of setting the vbe mode in fbdrv config(without mag) but when I combine fbdrv and pci direct access configs I cannot see any message from fbdrv. Abhishek Gupta

L4Android performance issue
by Haohui Mai 13 Jul '12

13 Jul '12

Hi, I just got a chance to run both L4Android and Android-x86 on an Asus EEE PC to measure their performance. In short, it seems to me that mag is causing some problem. I ran the Android web browser, and measured the page load latency to measure the performance of both system. I tried to keep the configuration of both side the same. For example, both system only use VESA, and they share the same userspace binaries. L4Android did well in some cases, however, I saw more than 2x slow down from L4Android (notably http://www.android.com) I suspect that this comes from mag -- I noticed that the graphics performance of L4Android is not great, for example, even boot animation lags on L4Android. I suspect it'll take some time to fix, so is there a way to disable mag and let l4linux takes care of the frame buffer directly? Thanks. ~Haohui

Hi Adam, It is not decided yet which graphics card will be used. Basically, we are just trying to check whether the idea of doing this works or not. If I can get xserver running on l4linux on kvm then the graphics card will be decided. Do you have any suggestions?? Abhishek Gupta
