[Qemu-devel] [PULL] RISC-V Patches for 4.0-rc3, v2

RISC-V Patches for 4.0-rc3, v2

This patch set contains a pair of tightly coupled PLIC bug fixes:

* We were calculating the PLIC addresses incorrectly.
* We were installing the wrong number of PLIC interrupts.

The two bugs togther resulted in a mostly-working system, but they're
impossible to seperate because fixing one bug would result in
significant breakage.  As a result they're in the same patch.

There is also a cleanup to use qemu_log_mask(LOG_GUEST_ERROR,...) for
error reporting.

As far as I know these are the last outstanding RISC-V patches for 4.0.

v2 no longer fails "make check" for me... sorry!

[Qemu-devel] [PULL 1/2] riscv: plic: Fix incorrect irq calculation

[Palmer Dabbelt]

From: Alistair Francis <Alistair.Francis@wdc.com>

This patch fixes four different things, to maintain bisectability they
have been merged into a single patch. The following fixes are below:

sifive_plic: Fix incorrect irq calculation
The irq is incorrectly calculated to be off by one. It has worked in the
past as the priority_base offset has also been set incorrectly. We are
about to fix the priority_base offset so first first the irq
calculation.

sifive_u: Fix PLIC priority base offset and numbering
According to the FU540 manual the PLIC source priority address starts at
an offset of 0x04 and not 0x00. The same manual also specifies that the
PLIC only has 53 source priorities. Fix these two incorrect header
files.

We also need to over extend the plic_gpios[] array as the PLIC sources
count from 1 and not 0.

riscv: sifive_e: Fix PLIC priority base offset
According to the FE31 manual the PLIC source priority address starts at
an offset of 0x04 and not 0x00.

riscv: virt: Fix PLIC priority base offset
Update the virt offsets based on the newly updated SiFive U and SiFive E
offsets.

[Qemu-devel] [PULL 2/2] riscv: plic: Log guest errors

[Palmer Dabbelt]

From: Alistair Francis <Alistair.Francis@wdc.com>

Instead of using error_report() to print guest errors let's use
qemu_log_mask(LOG_GUEST_ERROR,...) to log the error.

[Qemu-riscv] [PULL 2/2] riscv: plic: Log guest errors

[Palmer Dabbelt]

From: Alistair Francis <Alistair.Francis@wdc.com>

Instead of using error_report() to print guest errors let's use
qemu_log_mask(LOG_GUEST_ERROR,...) to log the error.
