2024-07-17qapi/machine: Clean up documentation around CpuInstancePropertiesMarkus Armbruster1-7/+6
CpuInstanceProperties' doc comment describes its members as properties to be passed to device_add when hot-plugging a CPU. This was in fact the initial use of this type, with query-hotpluggable-cpus: letting management applications find out what properties need to be passed with device_add to hot-plug a CPU. We've since added other uses: set-numa-node (commit 419fcdec3c1 and f3be67812c2), and query-cpus-fast (commit ce74ee3dea6). These are not about device-add. query-hotpluggable-cpus uses CpuInstanceProperties within HotpluggableCPU. Lift the documentation related to device-add from CpuInstanceProperties to HotpluggableCPU.

2024-07-16ui/console: Remove dpy_cursor_define_supported()Akihiko Odaki4-22/+2
Remove dpy_cursor_define_supported() as it brings no benefit today and it has a few inherent problems. All graphical displays except egl-headless support cursor composition without DMA-BUF, and egl-headless is meant to be used in conjunction with another graphical display, so dpy_cursor_define_supported() always returns true and meaningless. Even if we add a new display without cursor composition in the future, dpy_cursor_define_supported() will be problematic as a cursor display fix for it because some display devices like virtio-gpu cannot tell the lack of cursor composition capability to the guest and are unable to utilize the value the function returns. Therefore, all non-headless graphical displays must actually implement cursor composition for correct cursor display. Another problem with dpy_cursor_define_supported() is that it returns true even if only some of the display listeners support cursor composition, which is wrong unless all display listeners that lack cursor composition is headless.

2024-07-16ui/cocoa: Add cursor compositionAkihiko Odaki2-1/+101
Add accelerated cursor composition to ui/cocoa. This does not only improve performance for display devices that exposes the capability to the guest according to dpy_cursor_define_supported(), but fixes the cursor display for devices that unconditionally expects the availability of the capability (e.g., virtio-gpu). The common pattern to implement accelerated cursor composition is to replace the cursor and warp it so that the replaced cursor is shown at the correct position on the guest display for relative pointer devices. Unfortunately, ui/cocoa cannot do the same because warping the cursor position interfers with the mouse input so it uses CALayer instead; although it is not specialized for cursor composition, it still can compose images with hardware acceleration.

2024-07-16esp: remove transfer size check from DMA DATA IN and DATA OUT transfersMark Cave-Ayland1-2/+2
The transfer size check was originally added to prevent consecutive DMA TI commands from causing an assert() due to an existing SCSI request being in progress, but since the last set of updates [*] this is no longer required. Remove the transfer size check from DMA DATA IN and DATA OUT transfers so that issuing a DMA TI command when there is no data left to transfer does not cause an assert() due to an existing SCSI request being in progress.

2024-07-16accel/tcg: Make cpu_exec_interrupt hook mandatoryPeter Maydell2-2/+8
The TCGCPUOps::cpu_exec_interrupt hook is currently not mandatory; if it is left NULL then we treat it as if it had returned false. However since pretty much every architecture needs to handle interrupts, almost every target we have provides the hook. The one exception is Tricore, which doesn't currently implement the architectural interrupt handling. Add a "do nothing" implementation of cpu_exec_hook for Tricore, assert on startup that the CPU does provide the hook, and remove the runtime NULL check before calling it.

The function ufs_is_mcq_reg() and ufs_is_mcq_op_reg() only evaluated the range of the mcq_reg and mcq_op_reg offset, which is defined as a constant. Therefore, it was possible for them to return true even though the ufs device is configured to not support the mcq. This could cause ufs_mmio_read()/ufs_mmio_write() to result in Null-pointer-dereference. So fix it.

2024-07-12Python: bump minimum sphinx version to 3.4.3John Snow2-5/+4
With RHEL 8 support retired (It's been two years since RHEL9 released), our very oldest build platform version of Sphinx is now 3.4.3; and keeping backwards compatibility for versions as old as v1.6 when using domain extensions is a lot of work we don't need to do. This patch is motivated by my work creating a new QAPI domain, which unlike the dbus documentation, cannot be allowed to regress by creating a "dummy" doc when operating under older sphinx versions. Easier is to raise our minimum version as far as we can push it forwards, reducing my burden in creating cross-compatibility hacks and patches. A sampling of sphinx versions from various distributions, courtesy https://repology.org/project/python:sphinx/versions Alpine 3.16: v4.3.0 (QEMU support ended 2024-05-23) Alpine 3.17: v5.3.0 Alpine 3.18: v6.1.3 Alpine 3.19: v6.2.1 Ubuntu 20.04 LTS: EOL Ubuntu 22.04 LTS: v4.3.2 Ubuntu 22.10: EOL Ubuntu 23.04: EOL Ubuntu 23.10: v5.3.0 Ubuntu 24.04 LTS: v7.2.6 Debian 11: v3.4.3 (QEMU support ends 2024-07-xx) Debian 12: v5.3.0 Fedora 38: EOL Fedora 39: v6.2.1 Fedora 40: v7.2.6 CentOS Stream 8: v1.7.6 (QEMU support ended 2024-05-17) CentOS Stream 9: v3.4.3 OpenSUSE Leap 15.4: EOL OpenSUSE Leap 15.5: 2.3.1, 4.2.0 and 7.2.6 RHEL9 / CentOS Stream 9 becomes the new defining factor in staying at Sphinx 3.4.3 due to downstream offline build requirements that force us to use platform Sphinx instead of newer packages from PyPI.
