A driver to let userspace turn iovecs into dma-bufs. Use case: Allows qemu pass around dmabufs for the guest framebuffer. https://www.kraxel.org/cgit/qemu/log/?h=sirius/udmabuf has an experimental patch. Also allows qemu to export guest virtio-gpu resources as host dmabufs. Should be possible

[Qemu-devel] [PATCH 5/9] hw/arm/bcm2836: Rename bcm2836 type/struct to bcm283x

Our BCM2836 type is really a generic one that can be any of the bcm283x family. Rename it accordingly. We change only the names which are visible via the header file to the rest of the QEMU code, leaving private function names in bcm2836.c as they are. This is a preliminary to making bcm283x be

[Qemu-devel] [PATCH 6/9] hw/arm/bcm2836: Create proper bcm2837 device

The bcm2837 is pretty similar to the bcm2836, but it does have some differences. Notably, the MPIDR affinity aff1 values it sets for the CPUs are 0x0, rather than the 0xf that the bcm2836 uses, and if this is wrong Linux will not boot. Rather than trying to have one device with properties that

[Qemu-devel] [PATCH 0/9] raspi3: various fixes for Linux booting

I had a go at booting Debian's Linux kernel on our raspi3 model. These patches fix a variety of bugs that were stopping that working: * the board was trying to boot in secure mode, which isn't right for AArch64 Linux kernels * the hw/arm/boot.c code didn't set SCR_EL3.HCE, which meant that

[Qemu-devel] [PATCH 8/9] hw/arm/bcm2836: Hardcode correct CPU type

Now we have separate types for BCM2386 and BCM2387, we might as well just hard-code the CPU type they use rather than having it passed through as an object property. This then lets us put the initialization of the CPU object in init rather than realize. Signed-off-by: Peter Maydell

[Qemu-devel] [PATCH 2/9] hw/arm/boot: assert that secure_boot and secure_board_setup are false for AArch64

Add some assertions that if we're about to boot an AArch64 kernel, the board code has not mistakenly set either secure_boot or secure_board_setup. It doesn't make sense to set secure_boot, because all AArch64 kernels must be booted in non-secure mode. It might in theory make sense to set

[Qemu-devel] [PATCH 7/9] hw/arm/bcm2836: Use correct affinity values for BCM2837

The BCM2837 sets the Aff1 field of the MPIDR affinity values for the CPUs to 0, whereas the BCM2836 uses 0xf. Set this correctly, as it is required for Linux to boot. Signed-off-by: Peter Maydell --- hw/arm/bcm2836.c | 7 ++- 1 file changed, 6 insertions(+), 1

[Qemu-devel] [PATCH 1/9] hw/arm/raspi: Don't do board-setup or secure-boot for raspi3

For the rpi1 and 2 we want to boot the Linux kernel via some custom setup code that makes sure that the SMC instruction acts as a no-op, because it's used for cache maintenance. The rpi3 boots AArch64 kernels, which don't need SMC for cache maintenance and always expect to be booted non-secure.

[Qemu-devel] [PATCH 3/9] hw/arm/boot: If booting a kernel in EL2, set SCR_EL3.HCE

If we're directly booting a Linux kernel and the CPU supports both EL3 and EL2, we start the kernel in EL2, as it expects. We must also set the SCR_EL3.HCE bit in this situation, so that the HVC instruction is enabled rather than UNDEFing. Otherwise at least some kernels will panic when trying to

[Qemu-devel] [PATCH 4/9] hw/arm/bcm2386: Fix parent type of bcm2386

The TypeInfo and state struct for bcm2386 disagree about what the parent class is -- the TypeInfo says it's TYPE_SYS_BUS_DEVICE, but the BCM2386State struct only defines the parent_obj field as DeviceState. This would have caused problems if anything actually tried to treat the object as a
