2 years agoof/fdt: Ignore disabled memory nodes
Andre Przywara [Tue, 17 May 2022 10:14:10 +0000 (11:14 +0100)]
of/fdt: Ignore disabled memory nodes

When we boot a machine using a devicetree, the generic DT code goes
through all nodes with a 'device_type = "memory"' property, and collects
all memory banks mentioned there. However it does not check for the
status property, so any nodes which are explicitly "disabled" will still
be added as a memblock.
This ends up badly for QEMU, when booting with secure firmware on
arm/arm64 machines, because QEMU adds a node describing secure-only
memory:
===================
secram@e000000 {
secure-status = "okay";
status = "disabled";
reg = <0x00 0xe000000 0x00 0x1000000>;
device_type = "memory";
};
===================

The kernel will eventually use that memory block (which is located below
the main DRAM bank), but accesses to that will be answered with an
SError:
===================
[    0.000000] Internal error: synchronous external abort: 96000050 [#1] PREEMPT SMP
[    0.000000] Modules linked in:

[    0.000000] sp : ffff80000a4b3d10
....
==================
The actual crash location and call stack will be somewhat random, and
depend on the specific allocation of that physical memory range.

As the DT spec[1] explicitly mentions standard properties, add a simple
check to skip over disabled memory nodes, so that we only use memory
that is meant for non-secure code to use.

That fixes booting a QEMU arm64 VM with EL3 enabled ("secure=on"), when
not using UEFI. In this case the QEMU generated DT will be handed on
to the kernel, which will see the secram node.
This issue is reproducible when using TF-A together with U-Boot as
firmware, then booting with the "booti" command.

When using U-Boot as an UEFI provider, the code there [2] explicitly
filters for disabled nodes when generating the UEFI memory map, so we
are safe.
EDK/2 only reads the first bank of the first DT memory node [3] to learn
about memory, so we got lucky there.

2 years agodt-bindings: timer: Update TI timer to yaml
Tony Lindgren [Thu, 14 Apr 2022 08:58:06 +0000 (11:58 +0300)]
dt-bindings: timer: Update TI timer to yaml

Let's update the TI timer binding to use yaml. As this binding is specific
to the TI dual-mode timers also known as dm-timers, let's use file name
ti,timer-dm.yaml to avoid confusion with other timers.

We add checks for the deprecated ti,hwmods property as done for other TI
device driver bindings earlier.

We also correct the issue with the old binding that was out of date for
several properties.

The am43 related timers are undocumented, but compatible with the am3
timers. Let's add the am43 timers too.

The dm814 and dm816 timers are missing, let's add them.

Some timers on some SoCs are dual mapped, like the ABE timers on omap4
and 5. The reg property maxItems must be updated to 2.

The timer clocks can be managed by the parent interconnect target module
with no clocks assigned for the timer node. And in some cases, the SoC may
need to configure additional system clock for the timer in addition to the
functional clock.

The clock names are optional and not specific to the comptible property.
For example, dra7 timers on l3 interconnect do not need clock-names, while
the timers on dra7 l4 interconnect need them with both being compatible
with ti,omap5430-timer.

2 years agoof/irq: Use interrupts-extended to find parent
Samuel Holland [Tue, 12 Apr 2022 05:15:28 +0000 (00:15 -0500)]
of/irq: Use interrupts-extended to find parent

The RISC-V PLIC binding uses interrupts-extended to specify its parent
domain(s). That binding does not allow the interrupt-parent property to
appear in the irqchip node. This prevents of_irq_init from properly
detecting the irqchip hierarchy.

If no interrupt-parent property is present in the enclosing bus or root
node, then desc->interrupt_parent will be NULL for both the per-CPU
RISC-V INTC (the actual root domain) and the RISC-V PLIC. Similarly, if
the bus or root node specifies `interrupt-parent = <&plic>`, then
of_irq_init will hit the `desc->interrupt_parent == np` check, and again
all parents will be NULL. So things happen to work today for some boards
due to Makefile ordering.

However, things break when another irqchip ("foo") is stacked on top of
the PLIC. The bus or root node will have `interrupt-parent = <&foo>`,
since that is what all of the other peripherals need. When of_irq_init
runs, it will try to find the PLIC's parent domain. of_irq_find_parent
will fall back to using the interrupt-parent property of the PLIC's
parent node (i.e. the bus or root node), and of_irq_init will see "foo"
as the PLIC's parent domain. But this is wrong, because "foo" is
actually the PLIC's child domain!

So of_irq_init wrongly attempts to init the stacked irqchip before the
PLIC. This fails and breaks booting.

Fix this by using the first node referenced by interrupts-extended as
the parent when that property is present. This allows of_irq_init to see
the relationship between the PLIC and the per-CPU RISC-V INTC, and thus
only the RISC-V INTC is (correctly) considered a root domain.
