This test boots a Linux kernel on a CubieBoard and verify
4
the serial output is working.

The kernel image and DeviceTree blob are built by the Armbian
7
project (based on Debian):

https://docs.armbian.com/Developer-Guide_Build-Preparation/

The cpio image used comes from the linux-build-test project:

https://github.com/groeck/linux-build-test

13
If ARM is a target being built, "make check-acceptance" will
14
automatically include this test by the use of the "arch:arm" tags.

Alternatively, this test can be run using:

By calling qdev_pass_gpios() we don't need to hold a copy of the
4
IRQs from the INTC into the SoC state.
5
Instead of filling an array of qemu_irq and passing it around, we
6
can now directly call qdev_get_gpio_in() on the SoC.

New patch

From: Masahiro Yamada <masahiroy@kernel.org>

According to the specification "Semihosting for AArch32 and Aarch64",
4
the SYS_OPEN operation should return:
5
6
- A nonzero handle if the call is successful
7
- -1 if the call is not successful
8
9
So, it should never return 0.
10
11
Prior to commit 35e9a0a8ce4b ("target/arm/arm-semi: Make semihosting
12
code hand out its own file descriptors"), the guest fd matched to the
13
host fd. It returned a nonzero handle on success since the fd 0 is
14
already used for stdin.
15
16
Now that the guest fd is the index of guestfd_array, it starts from 0.
17
18
I noticed this issue particularly because Trusted Firmware-A built with
19
PLAT=qemu is no longer working. Its io_semihosting driver only handles
20
a positive return value as a valid filehandle.
21
22
Basically, there are two ways to fix this:
23
24
- Use (guestfd - 1) as the index of guestfs_arrary. We need to insert
25
increment/decrement to convert the guestfd and the array index back
26
and forth.
27
28
- Keep using guestfd as the index of guestfs_array. The first entry
29
of guestfs_array is left unused.
30
31
I thought the latter is simpler. We end up with wasting a small piece
32
of memory for the unused first entry of guestfd_array, but this is
33
probably not a big deal.
34
35
Fixes: 35e9a0a8ce4b ("target/arm/arm-semi: Make semihosting code hand out its own file descriptors")

RNGB variant. These peripherals are included (at least) in imx25 and

The emulation supports the initial self test, reseeding the prng and

The wfi instruction can be configured to be trapped by a higher exception
4
level, such as the EL2 hypervisor. When the instruction is trapped, the
5
program counter should contain the address of the wfi instruction that
6
caused the exception. The program counter is adjusted for this in the wfi op
7
helper function.
8
9
However, this correction is done to env->pc, which only applies to AArch64
10
mode. For AArch32, the program counter is stored in env->regs[15]. This
11
adds an if-else statement to modify the correct program counter location
12
based on the the current CPU mode.

The IAR0/IAR1 register is used to acknowledge an interrupt - a read of the
4
register activates the highest priority pending interrupt and provides its
5
interrupt ID. Activating an interrupt can change the CPU's virtual interrupt
6
state - this change makes sure the virtual irq state is updated.

The IL bit is set for 32-bit instructions, thus passing false
4
with the is_16bit parameter to syn_data_abort_with_iss() makes
5
a syn mask that always has the IL bit set.
6
7
Pass is_16bit as true to make the initial syn mask have IL=0,
8
so that the final IL value comes from or'ing template_syn.

During the conversion to decodetree, the setting of
4
ISSIs16Bit got lost. This causes the guest os to
5
incorrectly adjust trapping memory operations.
