[libvirt] [v3] qemu: Support vram for video of qxl type

For qemu names the primary vga as "qxl-vga": 1) if vram is specified for 2nd qxl device: -vga qxl -global qxl-vga.vram_size=$SIZE \ -device qxl,id=video1,vram_size=$SIZE,... 2) if vram is not specified for 2nd qxl device, (use the default set by global): -vga qxl -global qxl-vga.vram_size=$SIZE \ -device qxl,id=video1,... For qemu names all qxl devices as "qxl": 1) if vram is specified for 2nd qxl device: -vga qxl -global qxl.vram_size=$SIZE \ -device qxl,id=video1,vram_size=$SIZE ... 2) if vram is not specified for 2nd qxl device: -vga qxl -global qxl-vga.vram_size=$SIZE \ -device qxl,id=video1,... "-global" is the only way to define vram_size for the primary qxl device, regardless of how qemu names it, (It's not good a good way, as original idea of "-global" is to set a global default for a driver property, but to specify vram for first qxl device, we have to use it). For other qxl devices, as they are represented by "-device", could specify it directly and seperately for each, and it overrides the default set by "-global" if specified. v1 - v2: * modify "virDomainVideoDefaultRAM" so that it returns 16M as the default vram_size for qxl device. * vram_size * 1024 (qemu accepts bytes for vram_size). * apply default vram_size for qxl device for which vram_size is not specified. * modify "graphics-spice" tests (more sensiable vram_size) * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr, to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr). v2 - v3: * Modify default video memory size for qxl device from 16M to 24M * Update codes to be consistent with changes on qemu_capabilities.* --- src/conf/domain_conf.c | 4 ++ src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 18 ++++++++++ tests/qemuhelptest.c | 1 + .../qemuxml2argv-graphics-spice-qxl-vga.args | 7 ++++ .../qemuxml2argv-graphics-spice-qxl-vga.xml | 36 ++++++++++++++++++++ .../qemuxml2argv-graphics-spice.args | 4 +- .../qemuxml2argv-graphics-spice.xml | 4 +- tests/qemuxml2argvtest.c | 4 ++ tests/qemuxml2xmltest.c | 1 + 11 files changed, 78 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-qxl-vga.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-graphics-spice-qxl-vga.xml diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index c8350c6..16e1291 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -4167,6 +4167,10 @@ virDomainVideoDefaultRAM(virDomainDefPtr def, /* Original Xen PVFB hardcoded to 4 MB */ return 4 * 1024; + case VIR_DOMAIN_VIDEO_TYPE_QXL: + /* QEMU use 64M as the minimal video video memory for qxl device */ + return 64 * 1024; + default: return 0; } diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 477924d..d8aa9cd 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -1122,6 +1122,8 @@ qemuCapsParseDeviceStr(const char *str, virBitmapPtr flags) } if (strstr(str, "virtio-net-pci.tx=")) qemuCapsSet(flags, QEMU_CAPS_VIRTIO_TX_ALG); + if (strstr(str, "name \"qxl-vga\"")) + qemuCapsSet(flags, QEMU_CAPS_DEVICE_QXL_VGA); return 0; } diff --git a/src/qemu/qemu_capabilities.h b/src/qemu/qemu_capabilities.h index a61b088..68c5958 100644 --- a/src/qemu/qemu_capabilities.h +++ b/src/qemu/qemu_capabilities.h @@ -94,6 +94,7 @@ enum qemuCapsFlags { QEMU_CAPS_CHARDEV_SPICEVMC = 56, /* newer -chardev spicevmc */ QEMU_CAPS_DEVICE_SPICEVMC = 57, /* older -device spicevmc*/ QEMU_CAPS_VIRTIO_TX_ALG = 58, /* -device virtio-net-pci,tx=string */ + QEMU_CAPS_DEVICE_QXL_VGA = 59, /* Is the primary and vga campatible qxl device named qxl-vga? */ QEMU_CAPS_LAST, /* this must always be the last item */ }; diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index fa60abe..198a4e2 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -1931,6 +1931,12 @@ qemuBuildVideoDevStr(virDomainVideoDefPtr video, virBufferVSprintf(&buf, "%s", model); virBufferVSprintf(&buf, ",id=%s", video->info.alias); + + if (video->type == VIR_DOMAIN_VIDEO_TYPE_QXL) { + /* QEMU accepts bytes for vram_size. */ + virBufferVSprintf(&buf, ",vram_size=%u", video->vram * 1024); + } + if (qemuBuildDeviceAddressStr(&buf, &video->info, qemuCaps) < 0) goto error; @@ -4033,6 +4039,18 @@ qemuBuildCommandLine(virConnectPtr conn, } virCommandAddArgList(cmd, "-vga", vgastr, NULL); + + if (def->videos[0]->type == VIR_DOMAIN_VIDEO_TYPE_QXL) { + if (def->videos[0]->vram && + qemuCapsGet(qemuCaps, QEMU_CAPS_DEVICE)) { + if (qemuCapsGet(qemuCaps, QEMU_CAPS_DEVICE_QXL_VGA)) + virCommandAddArgFormat(cmd, "-global qxl-vga.vram_size=%u", + def->videos[0]->vram * 1024); + else + virCommandAddArgFormat(cmd, "-global qxl.vram_size=%u", + def->videos[0]->vram * 1024); + } + } } } else { diff --git a/tests/qemuhelptest.c b/tests/qemuhelptest.c index 335364f..c86c578 100644 --- a/tests/qemuhelptest.c +++ b/tests/qemuhelptest.c @@ -489,6 +489,7 @@ mymain(int argc, char **argv) QEMU_CAPS_DRIVE_AIO, QEMU_CAPS_CCID_PASSTHRU, QEMU_CAPS_CHARDEV_SPICEVMC, + QEMU_CAPS_DEVICE_QXL_VGA, QEMU_CAPS_VIRTIO_TX_ALG); return ret == 0 ?
