i2c: ocores: add polling mode workaround for Sifive FU540-C000 SoC
The i2c-ocore driver already has a polling mode interface.But it needs
a workaround for FU540 Chipset on HiFive unleashed board (RevA00).
There is an erratum in FU540 chip that prevents interrupt driven i2c
transfers from working, and also the I2C controller's interrupt bit
cannot be cleared if set, due to this the existing i2c polling mode
interface added in mainline earlier doesn't work, and CPU stall's
infinitely, when-ever i2c transfer is initiated.
Ref:
commit dd7dbf0eb090 ("i2c: ocores: refactor setup for polling")
The workaround / fix under OCORES_FLAG_BROKEN_IRQ is particularly for
FU540-COOO SoC.
The polling function identifies a SiFive device based on the device node
and enables the workaround.

Add FU540-C000 specific device tree bindings to already available
i2-ocores file. This device is available on
HiFive Unleashed Rev A00 board. Move interrupt under optional
property list as this can be optional.
The FU540-C000 SoC from sifive, has an Opencore's I2C block

i2c: iop: Use GPIO descriptors
The IOP3xx has some elaborate code to directly slam the
GPIO lines multiplexed with I2C down low before enablement,
apparently a workaround for a hardware bug found in the
early chips.
After consulting the developer documentation for IOP80321
and IOP80331 I can clearly see that this may be useful for
IOP80321 family (mach-iop32x) but it is highly dubious for
any 80331 series or later chip: in these chips the lines
are not multiplexed for UARTs.
We convert the code to pass optional GPIO descriptors
and register these only on the 80321-based boards where
it makes sense, optionally obtain them in the driver and
use the gpiod_set_raw_value() to ascertain the line gets
driven low when needed.
The GPIO driver does not give the GPIO chip a reasonable
label so the patch also adds that so that these machine
descriptor tables can be used.

The S3C2410 does some funny dance around its pins:
- First try to call back to the platform to get and control
some GPIO pins
- If this doesn't work, it tries to get a pin control handle
- If this doesn't work, it retrieves two GPIOs from the device
tree node and does nothing with them
If we're gonna retrieve two GPIOs and do nothing with them, we
might as well do it using the GPIO descriptor API. When we use
the resource management API, the code gets smaller.

Model the I2C bus clock divider as a part of the Core Clock Framework.
Primarily this removes the clk_get_rate() call from each transfer.
This call causes problems for slave drivers that themselves have
internal clock components that are controlled by an I2C interface.
When the slave's internal clock component is prepared, the prepare
lock is obtained, and it makes calls to the I2C subsystem to
command the hardware to activate the clock. In order to perform
the I2C transfer, this driver sets the divider, which requires
it to get the parent clock rate, which it does with clk_get_rate().
Unfortunately, this function will try to take the clock prepare
lock, which is already held by the slave's internal clock calls
creating a deadlock.
Modeling the divider in the CCF natively removes this dependency
and the divider value is only set upon changing the bus clock
frequency or changes in the parent clock that cascade down to this
divisor. This obviates the need to set the divider with every
transfer and avoids the deadlock described above. It also should
provide better clock debugging and save a few cycles on each
transfer due to not having to recalcuate the divider value.

Currently we only create an I2C bus for the ports listed in the

at the port_max field of the status register.
This patch re-works the bus add logic so that we always create buses
for each port, unless the bus is marked as unavailable in the DT. This
is useful since it ensures that all the buses provided by the CFAM I2C

tracing: Silence GCC 9 array bounds warning
Starting with GCC 9, -Warray-bounds detects cases when memset is called
starting on a member of a struct but the size to be cleared ends up
writing over further members.
Such a call happens in the trace code to clear, at once, all members
after and including `seq` on struct trace_iterator:
In function 'memset',
inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3:
./include/linux/string.h:344:9: warning: '__builtin_memset' offset

referenced subobject 'seq' with type 'struct trace_seq' at offset
4368 [-Warray-bounds]
344 | return __builtin_memset(p, c, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to avoid GCC complaining about it, we compute the address
ourselves by adding the offsetof distance instead of referring
directly to the member.
Since there are two places doing this clear (trace.c and trace_kdb.c),
take the chance to move the workaround into a single place in
the internal header.

The fields filter would not work with child fields, as the respective

To reproduce, run on s390 (would work on other platforms, too, but would

- Run 'kvm_stat -d'
- Press 'f'
- Enter 'instruct'
Notice that events like instruction_diag_44 or instruction_diag_500 are not

With this patch, we will filter by matching events and their parents.
However, consider the following example where we filter by
instruction_diag_44:
Note that the parent ('exit_instruction') displays the total events, but
the childs listed do not match its total (256 instead of 276). This is

The memory slot size must be aligned to the host's page size. When
testing a guest with a 4k page size on a host with a 64k page size,
then 3 guest pages are not host page size aligned. Since we just need
a nearly arbitrary number of extra pages to ensure the memslot is not
aligned to a 64 host-page boundary for this test, then we can use
16, as that's 64k aligned, but not 64 * 64k aligned.

kvm: Check irqchip mode before assign irqfd
When assigning kvm irqfd we didn't check the irqchip mode but we allow
KVM_IRQFD to succeed with all the irqchip modes. However it does not
make much sense to create irqfd even without the kernel chips. Let's
provide a arch-dependent helper to check whether a specific irqfd is
allowed by the arch. At least for x86, it should make sense to check:
- when irqchip mode is NONE, all irqfds should be disallowed, and,
- when irqchip mode is SPLIT, irqfds that are with resamplefd should
be disallowed.
For either of the case, previously we'll silently ignore the irq or
the irq ack event if the irqchip mode is incorrect. However that can
cause misterious guest behaviors and it can be hard to triage. Let's
fail KVM_IRQFD even earlier to detect these incorrect configurations.
