The downside of guest side polling is that polling is performed even with other runnable tasks in the host. However, even if poll in kvm can aware whether or not other runnable tasks in the same pCPU, it can still incur extra overhead in over-subscribe scenario. Now we can just enable guest polling when dedicated pCPUs are available. Acked-by:

cpuidle-haltpoll can be built as a module to allow optional late load. Given we are setting @owner to THIS_MODULE, cpuidle will attempt to grab a module reference every time a cpuidle_device is registered -- so essentially all online cpus get a reference. This prevents for the module to be unloaded later, which makes the module_exit callback entirely unused. Thus remove the @owner and allow module to be unloaded.

When a user loads cpuidle-haltpoll on a non KVM guest the module will successfully load, even though idle driver registration didn't take place. We should instead return -ENODEV signaling the user that the driver can't be loaded, like other error paths in haltpoll_init(). An example of such error paths is when we return -EBUSY when attempting to register an idle driver when it had one already (e.g. intel_idle loads at boot and then we attempt to insert module cpuidle-haltpoll).

Right now, guest current governors have the following ratings: * ladder -> 10 * teo -> 19 * menu -> 20 * haltpoll -> 21 * ladder + nohz=off -> 25 haltpoll governor got introduced and it is now the default governor given its highest rating -- with ladder+nohz being the exception -- regardless of idle driver in the guest. An example of an undesirable case is x86 KVM guests with MWAIT which have intel_idle registered first, and consequently will have haltpoll be used as governor which would get limited to a poll state and state 1 and the other states wouldn't get used. To keep the previous defaults we decrease rating of governor to 9 (below current lowest rating) and thus rely on @governor switch on cpuidle_register_driver() to tie in haltpoll idle driver and governor together.

Joao Martins authored
The recently introduced haltpoll driver is largely only useful with haltpoll governor. To allow drivers to associate with a particular idle behaviour, add a @governor property to 'struct cpuidle_driver' and thus allow a cpuidle driver to switch to a *preferred* governor on idle driver registration. We save the previous governor, and when an idle driver is unregistered we switch back to that. The @governor can be overridden by cpuidle.governor= boot param or alternatively be ignored if the governor doesn't exist. Signed-off-by:

The resolution of the idle injection is limited to 1ms. If there is a need for an injection of 1.2 ms, it is not possible. The idle injection API is not yet used, so it is safe to convert the existing API to the new time unit instead of adding more functions. Convert to microsecond in order to use a finer grain time unit when injecting idle cycles. Signed-off-by:

The play_idle resolution is 1ms. The intel_powerclamp bases the idle duration on jiffies. The idle injection API is also using msec based duration but has no user yet. Unfortunately, msec based time does not fit well when we want to inject idle cycle precisely with shallow idle state. In order to set the scene for the incoming idle injection user, move the precision up to usec when calling play_idle. Signed-off-by:

When cpus != maxcpus cpuidle-haltpoll will fail to register all vcpus past the online ones and thus fail to register the idle driver. This is because cpuidle_add_sysfs() will return with -ENODEV as a consequence from get_cpu_device() return no device for a non-existing CPU. Instead switch to cpuidle_register_driver() and manually register each of the present cpus through cpuhp_setup_state() callbacks and future ones that get onlined or offlined. This mimmics similar logic that intel_idle does. Fixes: fa86ee90 ("add cpuidle-haltpoll driver") Signed-off-by:

Pull x86 fixes from Thomas Gleixner: "A set of fixes for x86: - Fix the bogus detection of 32bit user mode for uretprobes which caused corruption of the user return address resulting in application crashes. In the uprobes handler in_ia32_syscall() is obviously always returning false on a 64bit kernel. Use user_64bit_mode() instead which works correctly. - Prevent large page splitting when ftrace flips RW/RO on the kernel text which caused iTLB performance issues. Ftrace wants to be converted to text_poke() which avoids the problem, but for now allow large page preservation in the static protections check when the change request spawns a full large page. - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC is configured via device tree. In the device tree case the GSI 1:1 mapping is meaningless therefore the lower bound which protects the GSI range on ACPI machines is irrelevant. Return the lower bound which the core hands to the function instead of blindly returning 0 which causes the core to allocate the invalid virtual interupt number 0 which in turn prevents all drivers from allocating and requesting an interrupt. - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp APIC driver. That uses physical destination mode where LDR/DFR are ignored, but the initialization and the missing clear of LDR caused the APIC to be left in a inconsistent state on kexec/reboot. - Clear LDR when clearing the APIC registers so the APIC is in a well defined state. - Initialize variables proper in the find_trampoline_placement() code. - Silence GCC( build warning for the real mode part of the build" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm/cpa: Prevent large page split when ftrace flips RW on kernel text x86/build: Add -Wnoaddress-of-packed-member to REALMODE_CFLAGS, to silence GCC9 build warning x86/boot/compressed/64: Fix missing initialization in find_trampoline_placement() x86/apic: Include the LDR when clearing out APIC registers x86/apic: Do not initialize LDR and DFR for bigsmp uprobes/x86: Fix detection of 32-bit user mode x86/apic: Fix arch_dynirq_lower_bound() bug for DT enabled machines -

On embedded environments with hard memory limits it is a normal although rare case when skb can't be allocated on rx part under high traffic. In such OOM cases napi_complete_done() was not called. So the napi object became in an invalid state like it is "scheduled". Kernel do not re-schedules the poll of that napi object. Consequently, kernel can not remove that object the system hangs on `ifconfig down` waiting for a poll. We are fixing this by gracefully closing napi poll routine with correct invocation of napi_complete_done. This was reproduced with artificially failing the allocation of skb to simulate an "out of memory" error case and check that traffic does not get stuck.
