* vfio/igd: Remove generation limitation for IGD passthroughTomita Moeko2025-05-092-37/+27
| | | | | | | | | | | | | | | | | | | | Starting from Intel Core Ultra Series (Meteor Lake), Data Stolen Memory has became a part of LMEMBAR (MMIO BAR2) [1][2], meaning that BDSM and GGC register quirks are no longer needed on these platforms. To support Meteor/Arrow/Lunar Lake and future IGD devices, remove the generation limitation in IGD passthrough, and apply BDSM and GGC quirks only to known Gen6-12 devices.

| | | | | | | | | | | | | | | | | | | | Check the vendor and device ID on GVT-g mdev to ensure it is a supported device [1]. This extra check is required for automatically enabling OpRegion access later. Note that Cherryview and Gemini Lake are marked as supported here since current code cannot distinguish them with other Gen8 and Gen9 devices. Since mdev cannot be created on these devices, this has no functional impact.

| | | | | | | | | | | | | | | | | | | ASLS register represents the base address of OpRegion, and it is programmed with HPA. In IGD passthrough scenario, it needs to be reprogrammed with GPA by guest firmware. To prevent guest accessing wrong memory range, ASLS should always be emulated and cleared. In GVT-g scenario, emulating ASLS is unnecessary as access is handled by kvmgt backend [1].

| | | | | | | | | | | | | | | qemu-system-hppa shuts down automatically when the BIOS is unable to boot from any device. So this test currently fails occasionally when QEMU already quit, but the test still expected it to be around (e.g. to shut it down cleanly). Adding a "-no-shutdown" seems to make it reliable. While we're at it, also remove the stray "self.machine" in there that does not have any purpose. Signed-off-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Daniel P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emscripten does not support partial unmapping of mmapped memory regions[1].

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The proposed suggestion is not correct. First it is not necessary for *all* classes to be Zeroable, only for Rust-defined ones; classes defined in C never implement ObjectImpl. Second, the parent class field need not be Zeroable. For example, ChardevClass's chr_write and chr_be_event fields cannot be NULL, therefore ChardevClass cannot be Zeroable. However, char_class_init() initializes them, therefore ChardevClass could be subclassed by Rust code.

On Ubuntu, Rust versions up to 1.80 (?) are available as of this writing for both Jammy (22.04) and Noble (24.04). However, the path to rustc and rustdoc must be provided by hand to the configure script using either command line arguments or environment variables.
