- Display color is wrong with Mesa graphics on crosvm
- Display color is wrong with Swiftshader graphics on QEMU
- Video playback is not working properly with Mesa graphics
- ARM 32-bit only and 64-bit only targets
- Support for VFIO PCI GPU Passthrough
- Enforce SELinux on all targets (Currently did for libvirt-qemu)
| Item | Value | Description |
|---|---|---|
| Firmware (If available) | UEFI (Without secure boot) | Would not add support for BIOS. |
| Kernel (If using direct kernel boot) | $(PRODUCT_OUT)/kernel |
|
| Kernel cmdline (If using direct kernel boot) | Copy from BOARD_KERNEL_CMDLINE_BASE variable on BoardConfigCommon.mk in this repository. |
|
| RAM | At least 1024 MB | At least 2048 MB is preferred. Strongly recommended to add androidboot.low_perf=1 to kernel cmdline if it's below than 2048 MB. |
| Ramdisk (If using direct kernel boot) | $(PRODUCT_OUT)/combined-ramdisk.img for normal boot, or $(PRODUCT_OUT)/combined-ramdisk-recovery.img for recovery mode. |
|
| VirtIO disk 1 | Sized at least BOARD_SUPER_PARTITION_SIZE + 1 GB |
You can use $(PRODUCT_OUT)/disk-vda.img as the disk image. |
| VirtIO disk 2 | Sized at least 2 GB | There is no need of formatting it manually, It would get formatted when Android boots up. |
| Type | Models | Description |
|---|---|---|
| Console | Serial console, VirtIO | By default, Serial console is used for printing kernel messages, VirtIO is used for Android shell console. |
| Disk | USB, VirtIO | Must use VirtIO for boot devices. |
| Filesystem | virtiofs | virtiofs filesystem with tag "shared" will be automatically mounted at /mnt/vendor/shared. |
| Graphics | VirtIO (with or without 3D Acceleration) | Enable 3D Acceleration for Mesa graphics, Disable 3D Acceleration for Swiftshader graphics. |
| Keyboard | PS/2, USB, VirtIO | PS/2 isn't supported when using emulator prebuilt kernel. |
| Machine type (QEMU arm64) | virt | |
| Mouse | PS/2, USB, VirtIO | PS/2 isn't supported when using emulator prebuilt kernel. |
| Network Interface Card | VirtIO | |
| Sound card | Intel AC97, Intel ICH6, Intel ICH9, USB, VirtIO | Prefer VirtIO sound card, then Intel AC97. Intel sound cards aren't supported when using emulator prebuilt kernel. |
| Tablet input | USB, VirtIO | Does not show mouse cursor, Should be used only if the VM viewer has touchscreen. |
| Parameter | Possible values | Description |
|---|---|---|
