2016-09-13tests: fix qvirtqueue_kickLaurent Vivier
vq->avail.idx and vq->avail->ring[] are a 16bit values, so read and write them with readw()/writew() instead of readl()/writel(). To read/write a 16bit value with a 32bit accessor works fine on little-endian CPU but not on big endian CPU. [An equivalent patch for the writew() calls was also sent by Zhang Shuai <zhangshuai13@huawei.com>. --Stefan] Signed-off-by: Laurent Vivier <lvivier@redhat.com> Message-id: 1472330054-22607-1-git-send-email-lvivier@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2016-06-20libqos: add qvirtqueue_cleanup()Stefan Hajnoczi
qvirtqueue_setup() allocates the vring and virtqueue state. So far there has been no function to free it. Callers have been using guest_free() for the vring but forgot to free the QVirtQueue state. This patch solves the memory leak by introducing qvirtqueue_cleanup(). Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2016-06-20libqos: drop duplicated virtio_ring.h bit definitionsStefan Hajnoczi
Note that virtio_ring.h defines feature bits using their bit number: #define VIRTIO_RING_F_INDIRECT_DESC 28 On the other hand libqos virtio.h uses the bit mask: #define QVIRTIO_F_RING_INDIRECT_DESC 0x10000000 The patch makes the necessary adjustments. I have used "1u << BITMASK" instead of "1ULL << BITMASK" because the 64-bit feature fields are not implemented in libqos virtio.

Much of fw_cfg.h's contents is #ifndef NO_QEMU_PROTOS. This lets a few places include it without satisfying the dependencies of the suppressed code. If you somehow include it with NO_QEMU_PROTOS, any future includes are ignored. Unnecessarily unclean.

2016-03-21tests/libqos/pci-pc: Fix qpci_pc_iomap() to map BARs alignedMarkus Armbruster
qpci_pc_iomap() maps BARs one after the other, without padding. This is wrong. PCI Local Bus Specification Revision 3.0, 6.2.5.1. Address Maps: "all address spaces used are a power of two in size and are naturally aligned". That's because the size of a BAR is given by the number of address bits the device decodes, and the BAR needs to be mapped at a multiple of that size to ensure the address decoding works. Fix qpci_pc_iomap() accordingly. This takes care of a FIXME in ivshmem-test.

As part of streamlining the AHCI tests interface, it'd be nice if specying a size of zero could be handled without special branches and the allocator could handle this special case gracefully.

2016-01-11libqos/ahci: Switch to mutable propertiesJohn Snow
ATAPI commands are, unfortunately, weird in that they can be either DMA or PIO depending on a header bit. In order to accommodate them, I'll need to make AHCI command properties mutable so we can toggle between which "flavor" of ATAPI command we want to test. The default ATAPI transfer mechanism is PIO and the default properties are adjusted accordingly.

2016-01-11libqos/ahci: ATAPI supportJohn Snow
