2015-05-31Add stream ID to MSI writePavel Fedin
GICv3 ITS distinguishes between devices by using hardwired device IDs passed on the bus. This patch implements passing these IDs in qemu. SMMU is also known to use stream IDs, therefore this addition can also be useful for implementing platforms with SMMU. Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Changes from v1: - Added bus number to the stream ID - Added stream ID not only to MSI-X, but also to plain MSI. Some common code was made into msi_send_message() function.

2015-04-27pci: remove hard-coded bar size in msix_init_exclusive_bar()Jason Wang
This patch lets msix_init_exclusive_bar() can calculate the bar and pba size based on the number of MSI-X vectors other than using a hard-coded limit 4096. This is needed to allow device to have more than 128 MSI_X vectors. To keep migration compatibility, keep using 4096 as bar size and 2048 for pba offset. Notes: We don't care about the case that using vectors > 128 for legacy machine type. Since we limit the queue max to 64, so vectors >= 65 is meaningless. Virtio device will be the first user for this. Cc: Keith Busch <keith.busch@intel.com> Cc: Kevin Wolf <kwolf@redhat.com> Cc: Stefan Hajnoczi <stefanha@redhat.com> Cc: Michael S.

2015-04-26Switch non-CPU callers from ld/st*_phys to address_space_ld/st*Peter Maydell
Switch all the uses of ld/st*_phys to address_space_ld/st*, except for those cases where the address space is the CPU's (ie cs->as). This was done with the following script which generates a Coccinelle patch. A few over-80-columns lines in the result were rewrapped by hand where Coccinelle failed to do the wrapping automatically, as well as one location where it didn't put a line-continuation '\' when wrapping lines on a change made to a match inside a macro definition. ===begin=== #!/bin/sh -e # Usage: # ./ldst-phys.spatch.sh > ldst-phys.spatch # spatch -sp_file ldst-phys.spatch -dir . | sed -e '/^+/s/\t/ /g' > out.patch # patch -p1 < out.patch for FN in ub uw_le uw_be l_le l_be q_le q_be uw l q; do cat <<EOF @ cpu_matches_ld_${FN} @ expression E1,E2; identifier as; @@ ld${FN}_phys(E1->as,E2) @ other_matches_ld_${FN} depends on !cpu_matches_ld_${FN} @ expression E1,E2; @@ -ld${FN}_phys(E1,E2) +address_space_ld${FN}(E1,E2, MEMTXATTRS_UNSPECIFIED, NULL) EOF done for FN in b w_le w_be l_le l_be q_le q_be w l q; do cat <<EOF @ cpu_matches_st_${FN} @ expression E1,E2,E3; identifier as; @@ st${FN}_phys(E1->as,E2,E3) @ other_matches_st_${FN} depends on !cpu_matches_st_${FN} @ expression E1,E2,E3; @@ -st${FN}_phys(E1,E2,E3) +address_space_st${FN}(E1,E2,E3, MEMTXATTRS_UNSPECIFIED, NULL) EOF done ===endit=== Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.

2014-08-14pci: Use bus master address space for delivering MSI/MSI-X messagesJan Kiszka
The spec says (and real HW confirms this) that, if the bus master bit is 0, the device will not generate any PCI accesses. MSI and MSI-X messages fall among these, so we should use the corresponding address space to deliver them. This will prevent delivery if bus master support is disabled.
