[Qemu-devel] [PATCH v4 1/1] intel_iommu: Add support for translation for devices behind bridges

- Use a hash table indexed on bus pointers to store information about buses instead of using the bus numbers. Bus pointers are stored in a new VTDBus struct together with the vector of device address space pointers indexed by devfn. - The bus number is still used for lookup for selective SID

[Qemu-devel] [PATCH v4 0/1] intel_iommu: Add support for translation for devices behind bridges

This patch set has been completely reimplemented according to ideas from the discussion of v2. It still solves the same problem, but does so only within the Intel IOMMU code and Q35, without changing the IOMMU interface. This eliminates the need for any separate interface change patch. This is

[Qemu-devel] Triggering two arm processors from same interrupt (A9 and M3)

Hello again, My next question is still related with M3 and A9 board what I want to model. This time my peripheral has some interrupts that are connected both to A9 processor(gic), and M3 processor (nvic). Additionally those interrupts have same number. Currently I use only two in my model so I

[Qemu-devel] [PATCH v3] cpu-exec: Fix compiler warning (-Werror=clobbered)

Reloading of local variables after sigsetjmp is only needed for some buggy compilers. The code which should reload these variables causes compiler warnings with gcc 4.7 when compiler optimizations are enabled: cpu-exec.c:204:15: error: variable ‘cpu’ might be clobbered by ‘longjmp’ or ‘vfork’
