The check for any active GPEs added by commit fdde0ff8590b ("ACPI:
PM: s2idle: Prevent spurious SCIs from waking up the system") turns
out to be insufficiently precise to prevent some systems from
resuming prematurely due to a spurious EC wakeup, so refine it
by first checking if any GPEs other than the EC GPE are active
and skipping all of the SCIs coming from the EC that do not produce
any genuine wakeup events after processing.Link: https://bugzilla.kernel.org/show_bug.cgi?id=206629

The check carried out by acpi_any_gpe_status_set() is not precise enough
for the suspend-to-idle implementation in Linux and in some cases it is
necessary make it skip one GPE (specifically, the EC GPE) from the check
to prevent a race condition leading to a premature system resume from
occurring.For this reason, redefine acpi_any_gpe_status_set() to take the number
of a GPE to skip as an argument.Link: https://bugzilla.kernel.org/show_bug.cgi?id=206629

Commit 3f8fd02b1bf1 ("mm/vmalloc: Sync unmappings in
__purge_vmap_area_lazy()") introduced a call to vmalloc_sync_all() in
the vunmap() code-path. While this change was necessary to maintain
correctness on x86-32-pae kernels, it also adds additional cycles for
architectures that don't need it.Specifically on x86-64 with CONFIG_VMAP_STACK=y some people reported
severe performance regressions in micro-benchmarks because it now also
calls the x86-64 implementation of vmalloc_sync_all() on vunmap(). But
the vmalloc_sync_all() implementation on x86-64 is only needed for newly
created mappings.To avoid the unnecessary work on x86-64 and to gain the performance
back, split up vmalloc_sync_all() into two functions:* vmalloc_sync_mappings(), and
* vmalloc_sync_unmappings()Most call-sites to vmalloc_sync_all() only care about new mappings being
synchronized. The only exception is the new call-site added in the
above mentioned commit.Shile Zhang directed us to a report of an 80% regression in reaim
throughput.Fixes: 3f8fd02b1bf1 ("mm/vmalloc: Sync unmappings in __purge_vmap_area_lazy()")

The reason for clearing boot_ec_is_ecdt in acpi_ec_add() (if a
PNP0C09 device object matching the ECDT boot EC had been found in
the namespace) was to cause acpi_ec_ecdt_start() to return early,
but since the latter does not look at boot_ec_is_ecdt any more,
acpi_ec_add() need not clear it.Moreover, doing that may be confusing as it may cause "DSDT" to be
printed instead of "ECDT" in the EC initialization completion
message, so stop doing it.While at it, split the EC initialization completion message into
two messages, one regarding the boot EC and another one printed
regardless of whether or not the EC at hand is the boot one.Signed-off-by: Rafael J. Wysocki
-
Notice that the return value of acpi_ec_init() is discarded anyway,
so it can be void and it doesn't need to check the return values of
acpi_bus_register_driver() and acpi_ec_ecdt_start() called by it.
Thus the latter can be void too and it really has nothing to do
if acpi_ec_add() has already found an EC matching the boot one in the
namespace. Also, acpi_ec_ecdt_get_handle() can be folded into it.Modify the code accordingly and while at it create a propoer kerneldoc
comment to document acpi_ec_ecdt_start() and move the remark regarding
ASUS X550ZE along with the related bug URL from acpi_ec_init() into
that comment.Additionally, fix up a stale comment in acpi_ec_init().

Commit 406857f773b0 ("ACPI: EC: add support for hardware-reduced
systems") made ec_install_handlers() return an error on failures
to configure a GPIO IRQ for the EC, but that is inconsistent with
the handling of the GPE event handler installation failures even
though it is exactly the same issue and the driver can respond to
it in the same way in both cases (the EC can be actively polled
for events through its registers if the event handler installation
fails).Moreover, it requires acpi_ec_add() to take that special case into
account and disagrees with the ec_install_handlers() header comment.For this reason, rework the event handler installation code in
ec_install_handlers() to explicitly take deferred probing (that
may be needed in the GPIO IRQ case) into account and to avoid
failing the EC initialization in any other case.Among other things, reduce code duplication between
install_gpe_event_handler() and install_gpio_irq_event_handler() by
moving some code from there into ec_install_handlers() itself and
simplify the error code path in acpi_ec_add().While at it, turn the ec_install_handlers() header comment into
a proper kerneldoc one and add some general control flow information
to it.Signed-off-by: Rafael J. Wysocki

If the boot EC comes from the DSDT, its ACPI handle is equal to the
handle of a device object with the PNP0C09 device ID. If that
device object is passed to acpi_ec_add(), it is not necessary to
allocate a new EC structure for it and parse it, because that has
been done already, so change the function to use the fast path in
that case.Signed-off-by: Rafael J. Wysocki
-
First, notice that if the device ID in acpi_ec_add() is equal to
ACPI_ECDT_HID, boot_ec_is_ecdt must be set, because this means
that the device object passed to acpi_ec_add() comes from
acpi_ec_ecdt_start() which fails if boot_ec_is_ecdt is unset.
Accordingly, boot_ec_is_ecdt need not be set again in that case,
so drop that redundant update of it from the code.Next, ec->handle must be a valid ACPI handle right before
returning 0 from acpi_ec_add(), because it either is the handle
of the device object passed to that function, or it is the boot EC
handle coming from acpi_ec_ecdt_start() which fails if it cannot
find a valid handle for the boot EC. Moreover, the object with
that handle is regarded as a valid representation of the EC in all
cases, so there is no reason to avoid the _DEP list update walk if
that handle is the boot EC handle. Accordingly, drop the dep_update
local variable from acpi_ec_add() and call acpi_walk_dep_device_list()
for ec->handle unconditionally before returning 0 from it.Finally, the ec local variable in acpi_ec_add() need not be
initialized to NULL and the status local variable declaration
can be moved to the block in which it is used, so change the code
in accordance with these observations.Signed-off-by: Rafael J. Wysocki

If the status value returned by acpi_install_address_space_handler()
in ec_install_handlers() is AE_NOT_FOUND, it is treated in a special
way, apparently because it might mean a _REG method evaluation
failure (at least that is the case according to the comment in
there), but acpi_install_address_space_handler() does not take
_REG evaluation errors into account at all, so the AE_NOT_FOUND
special handling is confusing at best.For this reason, change ec_install_handlers() to stop the EC and
return -ENODEV on all acpi_install_address_space_handler() errors.Signed-off-by: Rafael J. Wysocki

After commit 406857f773b0 ("ACPI: EC: add support for hardware-reduced
systems") the handle_events argument passed to ec_install_handlers()
and acpi_ec_setup() is redundant, because it is always 'false' when
the device argument passed to them in NULL and it is always 'true'
otherwise, so the device argument can be tested against NULL instead
of testing the handle_events one.Accordingly, modify ec_install_handlers() and acpi_ec_setup() to take
two arguments and reduce the number of checks in the former.Signed-off-by: Rafael J. Wysocki
-
It doesn't really make sense to pass ec->handle of the ECDT EC to
acpi_handle_info(), because it is set to ACPI_ROOT_OBJECT in
acpi_ec_ecdt_probe(), so rework acpi_ec_setup() to avoid using
acpi_handle_info() for printing messages.First, notice that the "Used as first EC" message is not really
useful, because it is immediately followed by a more meaningful one
from either acpi_ec_ecdt_probe() or acpi_ec_dsdt_probe() (the latter
also includes the EC object path), so drop it altogether.Second, use pr_info() for printing the EC configuration information.
While at it, make the code in question avoid printing invalid GPE or
IRQ numbers and make it print the GPE/IRQ information only when the
driver is ready to handle events.Fixes: 72c77b7ea9ce ("ACPI / EC: Cleanup first_ec/boot_ec code")

ACPICA commit 9383f5b01091e432c05f802a57edc20d329eec1f
Hibernation (S4) is triggered in a guest when it recieves a sleep
trigger from the hypervisor. When the guest resumes from this power
state, it does not see the sleep_enabled bit. In otherwords, the sleep
button is not enabled on waking from an S4 state. This causes
subsequent invocation of sleep state to fail in the guest.Fix this problem by enabling the sleep button in ACPI legacy wake.
