[Qemu-devel] [PULL 01/13] fsl-imx6: Swap Ethernet interrupt defines

[Peter Maydell]

From: Guenter Roeck <linux@roeck-us.net>

The sabrelite machine model used by qemu-system-arm is based on the
Freescale/NXP i.MX6Q processor. 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.

[Qemu-devel] [PULL 02/13] dump: Update correct kdump phys_base field for AArch64

[Peter Maydell]

From: Wei Huang <wei@redhat.com>

For guest kernel that supports KASLR, the load address can change every
time when guest VM runs. To find the physical base address correctly,
current QEMU dump searches VMCOREINFO for the string "NUMBER(phys_base)=".
However this string pattern is only available on x86_64. AArch64 uses a
different field, called "NUMBER(PHYS_OFFSET)=". This patch makes sure
QEMU dump uses the correct string on AArch64.

[Qemu-devel] [PULL 03/13] char: i.MX: Simplify imx_update()

[Peter Maydell]

From: Andrey Smirnov <andrew.smirnov@gmail.com>

Code of imx_update() is slightly confusing since the "flags" variable
doesn't really corespond to anything in real hardware and server as a
kitchensink accumulating events normally reported via USR1 and USR2
registers.

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.

[Qemu-devel] [PULL 05/13] hw/arm/raspi: Don't do board-setup or secure-boot for raspi3

[Peter Maydell]

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.
Don't fill in the aarch32-specific parts of the binfo struct.

[Qemu-devel] [PULL 06/13] hw/arm/boot: assert that secure_boot and secure_board_setup are false for AArch64

[Peter Maydell]

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 secure_board_setup, but
we don't currently support that, because only the AArch32
bootloader[] code calls this hook; bootloader_aarch64[] does not.
Since we don't have a current need for this functionality, just
assert that we don't try to use it. If it's needed we'll add
it later.

[Qemu-devel] [PULL 07/13] hw/arm/boot: If booting a kernel in EL2, set SCR_EL3.HCE

[Peter Maydell]

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 initialize KVM in the guest.

[Qemu-devel] [PULL 08/13] hw/arm/bcm2386: Fix parent type of bcm2386

[Peter Maydell]

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 TYPE_SYS_BUS_DEVICE.
Fix the TypeInfo to use TYPE_DEVICE as the parent, since we don't
need any of the additional functionality TYPE_SYS_BUS_DEVICE
provides.

[Qemu-devel] [PULL 09/13] hw/arm/bcm2836: Rename bcm2836 type/struct to bcm283x

[Peter Maydell]

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 an abstract
parent class to specific types for the bcm2836 and bcm2837.

[Qemu-devel] [PULL 10/13] hw/arm/bcm2836: Create proper bcm2837 device

[Peter Maydell]

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.

[Qemu-devel] [PULL 12/13] hw/arm/bcm2836: Hardcode correct CPU type

[Peter Maydell]

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.

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.

[Qemu-devel] [PULL 13/13] hw/arm/raspi: Provide spin-loop code for AArch64 CPUs

[Peter Maydell]

The raspi3 has AArch64 CPUs, which means that our smpboot
code for keeping the secondary CPUs in a pen needs to have
a version for A64 as well as A32. Without this, the
secondary CPUs go into an infinite loop of taking undefined
instruction exceptions.

(which avoids the problem by having the _iss() versions of the
function call the non-iss versions rather than duplicating
their function body; seems like better code anyway.)

[Qemu-devel] [PULL 00/13] target-arm queue

[Peter Maydell]

Here's the target-arm queue for 2.5: a few minor cleanups, one or
two small new features, and a pile of bug fixes.

Still on my to-review list for 2.5:
 * the breakpoint/singlestep fixes
 * highbank boot blob patchset
 * zynq ADC controller (maybe)

so I expect to do another pullreq before rc0.

thanks

Flushing the target-arm queue for softfreeze. I still have stuff
in my to-review queue but it mostly looked too RFC-ish/otherwise
not really 2.5 material, or just needs a bit more time on list for
review.

thanks
