The ARM architecture only saves the exit class to the HSR (ESR_EL2 for
arm64) on synchronous exceptions, not on asynchronous exceptions like an
IRQ. However, we only report the exception class on kvm_exit, which is
confusing because an IRQ looks like it exited at some PC with the same
reason as the previous exit. Add a lookup table for the exception index
and prepend the kvm_exit tracepoint text with the exception type to
clarify this situation.
Also resolve the exception class (EC) to a human-friendly text version
so the trace output becomes immediately usable for debugging this code.

We introduce kvm_arm_halt_guest and resume functions. They
will be used for IRQ forward state change.
Halt is synchronous and prevents the guest from being re-entered.
We use the same mechanism put in place for PSCI former pause,
now renamed power_off. A new flag is introduced in arch vcpu state,
pause, only meant to be used by those functions.

In case a vcpu off PSCI call is called just after we executed the
vcpu_sleep check, we can enter the guest although power_off
is set. Let's check the power_off state in the critical section,
just before entering the guest.

vhost drivers provide guest VMs with better I/O performance and lower
CPU utilization. This patch allows users to select vhost devices under
KVM configuration menu on ARM. This makes vhost support on arm/arm64
on a par with other architectures (e.g. x86, ppc).

The arch timer currently uses edge-triggered semantics in the sense that
the line is never sampled by the vgic and lowering the line from the
timer to the vgic doesn't have any effect on the pending state of
virtual interrupts in the vgic. This means that we do not support a
guest with the otherwise valid behavior of (1) disable interrupts (2)
enable the timer (3) disable the timer (4) enable interrupts. Such a
guest would validly not expect to see any interrupts on real hardware,
but will see interrupts on KVM.
This patch fixes this shortcoming through the following series of
changes.
First, we change the flow of the timer/vgic sync/flush operations. Now
the timer is always flushed/synced before the vgic, because the vgic
samples the state of the timer output. This has the implication that we
move the timer operations in to non-preempible sections, but that is
fine after the previous commit getting rid of hrtimer schedules on every
entry/exit.
Second, we change the internal behavior of the timer, letting the timer
keep track of its previous output state, and only lower/raise the line
to the vgic when the state changes. Note that in theory this could have
been accomplished more simply by signalling the vgic every time the
state *potentially* changed, but we don't want to be hitting the vgic
more often than necessary.
Third, we get rid of the use of the map->active field in the vgic and
instead simply set the interrupt as active on the physical distributor
whenever the input to the GIC is asserted and conversely clear the
physical active state when the input to the GIC is deasserted.
Fourth, and finally, we now initialize the timer PPIs (and all the other
unused PPIs for now), to be level-triggered, and modify the sync code to
sample the line state on HW sync and re-inject a new interrupt if it is
still pending at that time.

We currently schedule a soft timer every time we exit the guest if the
timer did not expire while running the guest. This is really not
necessary, because the only work we do in the timer work function is to
kick the vcpu.
Kicking the vcpu does two things:
(1) If the vpcu thread is on a waitqueue, make it runnable and remove it
from the waitqueue.
(2) If the vcpu is running on a different physical CPU from the one
doing the kick, it sends a reschedule IPI.
The second case cannot happen, because the soft timer is only ever
scheduled when the vcpu is not running. The first case is only relevant
when the vcpu thread is on a waitqueue, which is only the case when the
vcpu thread has called kvm_vcpu_block().
Therefore, we only need to make sure a timer is scheduled for
kvm_vcpu_block(), which we do by encapsulating all calls to
kvm_vcpu_block() with kvm_timer_{un}schedule calls.
Additionally, we only schedule a soft timer if the timer is enabled and
unmasked, since it is useless otherwise.
Note that theoretically userspace can use the SET_ONE_REG interface to
change registers that should cause the timer to fire, even if the vcpu
is blocked without a scheduled timer, but this case was not supported
before this patch and we leave it for future work for now.
Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
Some times it is useful for architecture implementations of KVM to know
when the VCPU thread is about to block or when it comes back from
blocking (arm/arm64 needs to know this to properly implement timers, for
example).
Therefore provide a generic architecture callback function in line with
what we do elsewhere for KVM generic-arch interactions.

ZONE_DMA for LPAE. Probably no need for stable on this one as we
only recently ran into this with the mainline kernel
- Fix imprecise external abort caused by bogus SRAM init. This affects
dm814x recently merged, so no need for stable on this one AFAIK

On am437x-gp-evm, pixcir_i2c_ts can wakeup the system from low power
state via pinctrl and IO daisy chain using generic wakeirq framework.
With commit 3fffd12839 ("i2c: allow specifying separate wakeup
interrupt in device tree") i2c core allows optional wakeirq to be
specified via device tree. Add wakeup irq entry to enable pixcir_i2c_ts
to wake the system from low power state.

With the current implementation of GPIO hogging and with
gpio-pcf857x is built as module, ethernet doesn't work on boot
and doesn't throw any error/warning to user. Ethernet becomes
operational when inserting gpio-pcf857x module, even this time
there is no error/warning logs to user that ethernet is
operational.
When using with NFS rootfs and gpio-pcf857x as module, board
doesn't boot as it doesn't get any ip address and doesn't throw
any error/warning. To over come this, now cpsw driver tries to
get mode-gpios. When gpio-pcf857x is built as module it will
throw error, so that user can decide either to built in
gpio-pcf857x to continue with nfs boot or choose alternate rootfs
filesystem like sd/ramdisk.
When using mmc/ramdisk as root fs, cpsw will probe defer and
re-probes again when gpio-pcf857x module is inserted and ethernet
becomes operational.

The vgic code on ARM is built for all configurations that enable KVM,
but the parent_data field that it references is only present when
CONFIG_IRQ_DOMAIN_HIERARCHY is set:
virt/kvm/arm/vgic.c: In function 'kvm_vgic_map_phys_irq':
virt/kvm/arm/vgic.c:1781:13: error: 'struct irq_data' has no member named 'parent_data'
This flag is implied by the GIC driver, and indeed the VGIC code only
makes sense if a GIC is present. This changes the CONFIG_KVM symbol
to always select GIC, which avoids the issue.

Install a non-faulting handler just before unmasking imprecise aborts
and switch back to the regular one after unmasking is done.
This catches any pending imprecise abort that the firmware/bootloader
may have left behind that would normally crash the kernel at that point.
As there are apparently a lot of bootlaoders out there that do such a
thing it makes sense to handle it in the common startup code.

Even if we eventually end up having only PMIC + MMC + eMMC + SDIO WLAN + SATA +
USB + HDMI configuration in the omap5-board-common.dtsi, this is the easiest
way to add support for other boards rather than diffing various versions of
out of tree dts files.
My guess is that also omap5-sbc-t54.dts can use this, but I don't have that
board so that will need to be dealt with later on.

Commit 99f84cae43 ("ARM: dts: add wl12xx/wl18xx bindings") added
device tree bindings for the TI WLAN SDIO on many omap variants.
I recall wondering how come omap5-uevm did not have the WLAN
added and this issue has been bugging me for a while now, and
I finally tracked it down to a bad pinmux regression, and a missing
deferred probe handling for the 32k clock from palmas that's
requested by twl6040.
Basically 392adaf796 ("ARM: dts: omap5-evm: Add mcspi data")
added pin muxing for mcspi4 that conflicts with the onboard
WLAN. While some omap5-uevm don't have WLAN populated, the
pins are not reused for other devices. And as the SDIO bus
should be probed, let's try to enable WLAN by default.
Let's fix the regression and add the WLAN configuration as
done for the other boards in 99f84cae43 ("ARM: dts: add
wl12xx/wl18xx bindings"). And let's use the new MMC pwrseq for
the 32k clock as suggested by Javier Martinez Canillas
<javier@dowhile0.org>.
Note that without a related deferred probe fix for twl6040,
the 32k clock is not initialized if palmas-clk is a module
and twl6040 is built-in.
Let's also use the generic "non-removable" instead of the
legacy "ti,non-removable" property while at it.
And finally, note that omap5 seems to require WAKEUP_EN for
the WLAN GPIO interrupt.

The z2 machine calls pxa27x_set_pwrmode() in order to power off
the machine, but this function gets discarded early at boot because
it is marked __init, as pointed out by kbuild:
WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode()
The function z2_power_off() references
the function __init pxa27x_set_pwrmode().
This is often because z2_power_off lacks a __init
annotation or the annotation of pxa27x_set_pwrmode is wrong.
This removes the __init section modifier to fix rebooting and the
build error.

The naming for the cpu_is macros is confusing as the CPU is separate
and within the SoC. Let's rename all the macros to soc_is, and let's
define cpu_is also for the ones still in use. Then we can just remove
the cpu_is macros once the users are fixed up.
To keep the chances of breaking anything, the changes were
generated with the following regular expressions:
s/cpu_is/soc_is/g
s/CPU/SoC/g
Then the list of existing cpu_is users was generated with:
$ $ grep -o -e 'cpu_is_.\+()' arch/arm/mach-omap2/*.[chS] | \
cut -d: -f2 | sort | uniq
And added to the end of the soc.h.
I decided to rework the earlier patches by Keerthy <j-keerthy@ti.com>
to keep changes down to minimum to avoid potential errors and stick
to just search and replace.

as it turns out, __omap_gptimer_init() and

Instead of forcing all those devices to pass
a use_gptimer cmdline argument, we add a new
function argument to __omap_sync32k_timer_init()
in preparation to deleting __omap_gptimer_init().
On a follow-up patch, we will remove uses of

- Remove legacy omap3 ISP code as the driver is DT only
- Remove VoiceBlue board support as it's been unused over
10 years now
- Remove unused polarity control macros for TWL
- Remove two unneeded semicolons
- Remove unused core dpll code for reprogramming the rates
Note that this branch is against v4.3-rc4 as that contains critical
MMC related fixes to boot with MMC working on most omaps.

Add cpu hotplug support for berlin SoCs such as BG2 and BG2Q. These SoC
don't support power off cpu independently, but we also want cpu hotplug
support in these SoCs. We achieve this goal by putting the dying CPU in
WFI state after the coherency is disabled, then asserting the dying CPU
reset bit to put the CPU in reset state.

In Berlin SoCs, there are two kinds of cpu reset control registers: the
first one's corresponding bits will be self-cleared after some cycles,
while the second one's bits won't. Previously the first kind of reset
control register is used, this patch uses the second kind one to prepare
for the next hotplug commit.

While the addition of these properties is technically correct it unveils
a bug with deferred probe. The problem is that the presence of the gpio-
range property causes the gpio-tegra driver to defer probe (it needs the
pinctrl driver to be ready). That's technically correct, but it causes a
couple of issues:
- The keyboard on Chromebooks stops working. The reason for that is
that the gpio-tegra device has not registered an IRQ domain by the
time the EC SPI device is registered, hence the interrupt number
resolves to 0. This is technically a bug in the SPI core, since it
should really resolve the interrupt at probe time and defer if the
IRQ domain isn't available yet. This is similar to what's done for
I2C and platform device already.
- The gpio-tegra device deferring probe means that it is moved to the
end of the dpm_list. This list defines the suspend/resume order for
devices. However the core lacks a way to move all users of the
gpio-tegra device to the end of the dpm_list at the same time. This
in turn results in a subtle bug on Jetson TK1, where the gpio-keys
device is used to expose the power key as input. The power key is a
convenient way to wake the system from suspend. Interestingly, the
gpio-keys device ends up getting probed at a point after gpio-tegra
has been probed successfully from having been deferred earlier. As
such the driver doesn't need to defer the probe itself, and hence
the device isn't moved to the end of the dpm_list. This causes the
gpio-tegra device to be suspended before gpio-keys, which in turn
leaves gpio-keys unable to wake the system from suspend.
There are patches in the works to fix both of the above issues, but they
are too involved to make it into v4.3, so in the meantime let's fix the
regressions by commenting out the gpio-ranges properties until the fixes
have landed.

0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.
In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is

For the consistency, use the latter for all the SoCs.

The OV9640 is not using a standard I2C protocol, but an SCCB variant. Maybe
it is not fully compatible in the fast mode. Therefore fast mode for normal
