[Qemu-devel] [PATCH] IRQ sharing in PCI bus
This allows multiple PCI devices on a bus to use the same IRQ lines. The signals from all devices are ORed. It will only work if the guest OS'es drivers supports that. Linux guest required that to have scsi disks and usb devices working at the same time on an emulated Versatile PB machine. qemu-pci-irq-sharing.patch Description: Binary data ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

[Qemu-devel] Linux ACPI RSDT probe bug
Hi, While moving the PCI, MP Table and ACPI table initialisation code to the Bochs BIOS, I found that even recent Linux kernels do not scan the ACPI RSDT table at the right addresses in the Extended BIOS Data Area. Does anyone know why it was never fixed ? It is very disturbing for QEMU because I would prefer not to patch the BIOS ROM to initialize the ACPI RSDT table.

One comment: you could move the DMA related functions and registers to sparc32_dma.c because it seems reasonnable that the DMA stuff was really implemented outside of the cs4231 chip (I believe the same chip was used in some PC cards with an ISA based DMA).

One comment: you could move the DMA related functions and registers to sparc32_dma.c because it seems reasonnable that the DMA stuff was really implemented outside of the cs4231 chip (I believe the same chip was used in some PC cards with an ISA based DMA). I had thought about that, but the CS and DMA registers are located in nearby addresses. Cleanest solution from the driver point of view would be that Qemu handled the case correctly where several drivers register non-overlapping memory areas of less than one page size within the same page. That way the DMA controller could reside in sparc32_dma.c and not know anything about CS registers and vice versa. Looks like the PC cards were called Windows Sound System compatible and there were several manufacturers in the early '90s. _ Express yourself instantly with MSN Messenger!

[Qemu-devel] qemu-i386 on ppc: tls issues
Hi, since I got my iBook (now running Linux), I always wanted to use qemu-i386 to run those fancy i386-only gimmicks like Flash player etc. Now, I finally got around to actually try to get it working, but I always fail with cannot set up thread-local storage: set_thread_area failed when setting up thread-local storage. Skimming the archives, I got a hint that tls and user emulation does not work together. Is this by design, or by lack of time?

[Qemu-devel] Is there any option to control the real-time clock?
Hi all !I would like to know if there is any option in Qemu to control the speed of the real-time clock, like in Bochs emulator?In Bochs, I can speed up the RTC, for example 2x, which means that all dialogs, that are time based (not CPU based) will run 2x faster... or 2x slower, depends on the setting. This is useful for some (DOS) software and debugging. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

Hi, I am looking for an explanation about kqemu is not free. I read somewhere I may not launch more than 4 instances of guests, with both 1Go of RAM each. I lost the link on wich I read that. I also lost the link where I saw some reason kqemu is not free (some relation with BOCHS, I think...) Would you help me to remind the reasons?

After having a cursory look at it only one thing really caught my attention: in the audio callback you set s-audio_free to the provided value, but then in you never use it. If i'm reading everything correctly this would lead to reading N bytes from DMA in write_audio, succeeding in writing only M bytes (where M N) to the audio subsystem and loosing N-M bytes forever. Basically you should never attempt to do volatile reads of more than audio_free bytes. SB16 operates in similar fashion. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
