2020-09-01meson: use meson datadir instead of qemu_datadirMarc-André Lureau
When cross-compiling, by default qemu_datadir is 'c:\Program Files\QEMU', which is not recognized as being an absolute path, and meson will end up adding the prefix again.

2020-08-27meson: move pixman detection to mesonPaolo Bonzini
When pixman is not installed (or too old), but virglrenderer is available and "configure" has been run with "--disable-system", the build currently aborts when trying to compile vhost-user-gpu (since it requires pixman). Let's skip the build of vhost-user-gpu when pixman is not installed or too old. Instead of adding CONFIG_PIXMAN, it is simpler to move the detection to pixman.

2020-08-21meson: rename included C source files to .c.incPaolo Bonzini
With Makefiles that have automatically generated dependencies, you generated includes are set as dependencies of the Makefile, so that they are built before everything else and they are available when first building the .c files. Alternatively you can use a fine-grained dependency, e.g. target/arm/translate.o: target/arm/decode-neon-shared.inc.c With Meson you have only one choice and it is a third option, namely "build at the beginning of the corresponding target"; the way you express it is to list the includes in the sources of that target. The problem is that Meson decides if something is a source vs. a generated include by looking at the extension: '.c', '.cc', '.m', '.C' are sources, while everything else is considered an include---including '.inc.c'. Use '.c.inc' to avoid this, as it is consistent with our other convention of using '.rst.inc' for included reStructuredText files. The editorconfig file is adjusted.

2020-06-12libvhost-user: advertise vring featuresStefan Hajnoczi
libvhost-user implements several vring features without advertising them. There is no way for the vhost-user master to detect support for these features. Things more or less work today because QEMU assumes the vhost-user backend always implements certain feature bits like VIRTIO_RING_F_EVENT_IDX. This is not documented anywhere. This patch explicitly advertises features implemented in libvhost-user so that the vhost-user master does not need to make undocumented assumptions. Feature bits that libvhost-user now advertises can be removed from vhost-user-blk.c. Devices should not be responsible for advertising vring feature bits, that is libvhost-user's job.

2020-06-12Lift max ram slots limit in libvhost-userRaphael Norwitz
Historically, VMs with vhost-user devices could hot-add memory a maximum of 8 times. Now that the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS protocol feature has been added, VMs with vhost-user backends which support this new feature can support a configurable number of ram slots up to the maximum supported by the target platform. This change adds VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS support for backends built with libvhost-user, and increases the number of supported ram slots from 8 to 32. Memory hot-add, hot-remove and postcopy migration were tested with the vhost-user-bridge sample.

When the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS protocol feature is enabled, on memory hot-unplug qemu will transmit memory regions to remove individually using the new message VHOST_USER_REM_MEM_REG message. With this change, vhost-user backends build with libvhost-user can now unmap individual memory regions when receiving the VHOST_USER_REM_MEM_REG message. Qemu only sends VHOST_USER_REM_MEM_REG messages when the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS feature is negotiated, and support for that feature has not yet been added in libvhost-user, this new functionality is not yet used.

2020-06-12Support ram slot configuration in libvhost-userRaphael Norwitz
The VHOST_USER_GET_MAX_MEM_SLOTS message allows a vhost-user backend to specify a maximum number of ram slots it is willing to support. This change adds support for libvhost-user to process this message. For now the backend will reply with 8 as the maximum number of regions supported. libvhost-user does not yet support the vhost-user protocol feature VHOST_USER_PROTOCOL_F_CONFIGIRE_MEM_SLOTS, so qemu should never send the VHOST_USER_GET_MAX_MEM_SLOTS message. Therefore this new functionality is not currently used.

2020-06-12Refactor out libvhost-user fault generation logicRaphael Norwitz
In libvhost-user, the incoming postcopy migration path for setting the backend's memory tables has become convolued. In particular, moving the logic which starts generating faults, having received the final ACK from qemu can be moved to a separate function. This simplifies the code substantially. This logic will also be needed by the postcopy path once the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS feature is supported.

2020-03-16build-sys: do not make qemu-ga link with pixmanMarc-André Lureau
Since commit d52c454aadcdae74506f315ebf8b58bb79a05573 ("contrib: add vhost-user-gpu"), qemu-ga is linking with pixman. This is because the Make-based build-system use a global namespace for variables, and we rely on "main.o-libs" for different linking targets. Note: this kind of variable clashing is hard to fix or prevent currently. meson should help, as declarations have a linear dependency and doesn't rely so much on variables and clever tricks. Note2: we have a lot of main.c (or other duplicated names!) in tree. Imho, it would be annoying and a bad workaroud to rename all those to avoid conflicts like I did here.

2020-03-16misc: Replace zero-length arrays with flexible array member (automatic)Philippe Mathieu-Daudé
Description copied from Linux kernel commit from Gustavo A. R. Silva (see [3]): --v-- description start --v-- The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being unadvertenly introduced [2] to the Linux codebase from now on. --^-- description end --^-- Do the similar housekeeping in the QEMU codebase (which uses C99 since commit 7be41675f7cb). All these instances of code were found with the help of the following Coccinelle script: @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; }; @@ identifier s, m, a; type t, T; @@ struct s { ... t m; - T a[0]; + T a[]; } QEMU_PACKED; [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76497732932f [3] https://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git/commit/?id=17642a2fbd2c1 Inspired-by: Gustavo A.

Add support for VHOST_USER_PROTOCOL_F_IN_BAND_NOTIFICATIONS, but as it's not desired by default, don't enable it unless the device implementation opts in by returning it from its protocol features callback. Note that I updated vu_set_vring_err_exec(), but didn't add any sending of the VHOST_USER_SLAVE_VRING_ERR message as there's no write to the err_fd today either. This also adds vu_queue_notify_sync() which can be used to force a synchronous notification if inband notifications are supported. Previously, I had left out the slave->master direction handling of F_REPLY_ACK, this now adds some code to support it as well.

2020-02-27libvhost-user-glib: fix VugDev main fd cleanupJohannes Berg
If you try to make a device implementation that can handle multiple connections and allow disconnections (which requires overriding the VHOST_USER_NONE handling), then glib will warn that we remove a src while it's still on the mainloop, and will poll() an FD that doesn't exist anymore. Fix this by making vug_source_new() require pairing with the new vug_source_destroy() so we can keep the GSource referenced in the meantime. Note that this requires calling the new API in vhost-user-input. vhost-user-gpu also uses vug_source_new(), but never seems to free the result at all, so I haven't changed anything there.

2019-10-26core: replace getpagesize() with qemu_real_host_page_sizeWei Yang
There are three page size in qemu: real host page size host page size target page size All of them have dedicate variable to represent. For the last two, we use the same form in the whole qemu project, while for the first one we use two forms: qemu_real_host_page_size and getpagesize(). qemu_real_host_page_size is defined to be a replacement of getpagesize(), so let it serve the role.

2019-09-04libvhost-user: introduce and use vu_has_protocol_feature()Johannes Berg
This simplifies the various has_feature() checks, we already have vu_has_feature() but it checks features, not protocol features.

2019-09-04libvhost-user: fix SLAVE_SEND_FD handlingJohannes Berg
It doesn't look like this could possibly work properly since VHOST_USER_PROTOCOL_F_SLAVE_SEND_FD is defined to 10, but the dev->protocol_features has a bitmap. I suppose the peer this was tested with also supported VHOST_USER_PROTOCOL_F_LOG_SHMFD, in which case the test would always be false, but nevertheless the code seems wrong. Use has_feature() to fix this.
