This SoC has an on-board ethernet controller which is supported in QEMU using the imx_fec.c module (actually called imx.enet for this model.) The include/hw/arm/fsm-imx6.h file defines the interrupt vectors for the imx.enet device like this: #define FSL_IMX6_ENET_MAC_1588_IRQ 118 #define FSL_IMX6_ENET_MAC_IRQ 119 According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf, page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary, interrupts are as follows. 150 ENET MAC 0 IRQ 151 ENET MAC 0 1588 Timer interrupt where 150 - 32 == 118 151 - 32 == 119 In other words, the vector definitions in the fsl-imx6.h file are reversed. Fixing the interrupts alone causes problems with older Linux kernels: The Ethernet interface will fail to probe with Linux v4.9 and earlier. Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe error handling. This is a Linux kernel problem, not a qemu problem: the Linux kernel only worked by accident since it requested both interrupts. For backward compatibility, generate the Ethernet interrupt on both interrupt lines. This was shown to work from all Linux kernel releases starting with v3.16.

Change the code to explicitly evaluate state of interrupts reported via USR1 and USR2 against corresponding masking bits and use the to detemine if IRQ line should be asserted or not. NOTE: Check for UTS1_TXEMPTY being set has been dropped for two reasons: 1. Emulation code implements a single character FIFO, so this flag will always be set since characters are trasmitted as a part of the code emulating "push" into the FIFO 2. imx_update() is really just a function doing ORing and maksing of reported events, so checking for UTS1_TXEMPTY should happen, if it's ever really needed should probably happen outside of it.

} DEFINE_MACHINE("raspi3", raspi3_machine_init) -- 2.16.2 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 configure it differently for the two cases, create two separate QOM devices for the two SoCs. We use the same approach as hw/arm/aspeed_soc.c and share code and have a data table that might differ per-SoC. For the moment the two types don't actually have different behaviour.

Note that this change means that it's no longer possible on the command line to use -cpu to ask for a different kind of CPU than the SoC supports. This was never a supported thing to do anyway; we were just not sanity-checking the command line. This does require us to only build the bcm2837 object on TARGET_AARCH64 configs, since otherwise it won't instantiate due to the missing cortex-a53 device and "make check" will fail.
