[Qemu-devel] [Bug 1645355] [NEW] x86: singlestepping through SYSCALL instruction causes exception in kernelspace

Public bug reported: Hi, The bug was originally reported [1] and [2] here. There is a problem inside QEMU with singlestepping from userspace until SYSCALL instruction is reached. The OS has in FMASK TF bit set, therefore there should be no singlestepping exception when transitioning to

Hi all, Ping? Thanks Rudolf Dne 14.8.2015 v 13:49 Rudolf Marek napsal(a): Hi all, I noticed that ATMU register reads on E500 are broken. Due to the wrong mask, some registers cannot be read and instead some other registers are read. Please see attached patch which fixes the problem. I also

Re: [Qemu-devel] [SeaBIOS] Graphics card pass-through working with two pass pci-initialization

Sorry I forgot to include all addresses. I don't know how much work it would be to generate the DSDT dynamically from Qemu, but IMHO that's the sanest way to make things flexible. We could probably even extract most information from the Qdev tree. Well I have written for coreboot a ACPI

Re: [Qemu-devel] [SeaBIOS] Graphics card pass-through working with two pass pci-initialization

Having a brief look at the coreboot code it seems static stuff (compiled by iasl) and dynamic bits are combined into the final dsdt table, is that correct? Yes the dsdt is static, it has just external references to ssdt which is dynamically generated using the acpigen. Acpigen can generate
