[RFC][PATCH 2/5] timekeeping: Fix potential lost pv notification of time change
In 780427f0e11 (Indicate that clock was set in the pvclock
gtod notifier), logic was added to pass a CLOCK_WAS_SET
notification to the pvclock notifier chain.
While that patch added a action flag returned from
accumulate_nsecs_to_secs(), it only uses the returned value
in one location, and not in the logarithmic accumulation.
This means if a leap second triggered during the logarithmic

[PATCH 2/4] time: add a notifier chain for when the system time is stepped
From: David Vrabel <david.vrabel@citrix.com>
The high resolution timer code gets notified of step changes to the
system time with clock_was_set() or clock_was_set_delayed() calls. If
other parts of the kernel require similar notification there is no
clear place to hook into.
Add a clock_was_set atomic notifier chain
(clock_was_set_notifier_list) and call this in place of
clock_was_set().

[PATCH 2/5] time: pass flags instead of multiple bools to timekeeping_update()
From: David Vrabel <david.vrabel@citrix.com>
Instead of passing multiple bools to timekeeping_updated(), define
flags and use a single ''action'' parameter. It is then more obvious
what each timekeeping_update() call does.

[hybrid]: hang in update_wall_time
Hi Ian/Stefano:
I changed over to the PV clock for hybrid liked we talked at the
hackathon. I still have the hang in update_wall_time() after dom0
switches to xen as clocksource.
The source of hang seems to be in xen stime_local_stamp in cpu_time that
suddenly jumps to a large 64bit value. I''ve been chasing to figure
where that happens, and why for the hybrid and not PV. It appears the

[RFC PATCH v2] Encode optimize using libNe10
Changes from RFC PATCH v1:
- passing arch parameter explicitly
- reduced stack usage by ~3.5K by using scaled NE10 fft version
- moved all optimization array functions to arm_celt_map.c
- Other cleanups pointed out by Timothy
Phil,
As you mentioned earlier, could you please address all
compile and linker errors/warnings coming out of Ne10 library?

[RFC PATCHv3] Encode optimize using libNe10
Changes from RFC PATCH v2
- fixed compile issue when just compiling for --enable-intrinsics
for ARMv7 without NE10
- Notes for NE10:
- All compile/link warnings are now in upstream NE10
- Only patch pending upstream in NE10 is the one that
needs to add -funsafe-math-optimizations for ARMv7
targets.
- Phil Wang @ ARM is working on getting this fixed.
- Note that even without

[RFC PATCH v1 0/2] Encode optimize using libNE10
Hello opus-dev,
I've been cooking up this patchset to integrate NE10 library into opus.
Current patchset focuses on encode use case mainly effecting performance of
clt_mdct_forward() and opus_fft() (for float only)
Glad to report the following on Encode use case:
(Measured on my Beaglebone Black Cortex-A8 board)
- Performance improvement for encode use case ~= 12.34% (Based on time -p

Hi All,
As per Timothy's suggestion, disabling mdct_forward
for fixed point. Only effects
armv7,armv8: Extend fixed fft NE10 optimizations to mdct
Rest of patches are same as in [1]
For reference, latest wip code for opus is at [2]
Still working with NE10 team at ARM to get corner cases of
mdct_forward. Will update with another patch
when issue in NE10 gets fixed.

Hi All,
Changes from RFC v2 [1]
armv7,armv8: Extend fixed fft NE10 optimizations to mdct
- Overflow issue fixed by Phil at ARM. Ne10 wip at [2]. Should be upstream soon.
- So, re-enabled using fixed fft for mdct_forward which was disabled in RFCv2

- Thanks to Jonathan Lennox, fixed some build fixes on iOS and some copy-paste errors

[RFC PATCH v1 0/8] Ne10 fft fixed and previous
Hello Timothy / Jean-Marc / opus-dev,
This patch series is follow up on work I posted on [1].
In addition to what was posted on [1], this patch series mainly
integrates Fixed point FFT implementations in NE10 library into opus.
You can view my opus wip code at [2].
Note that while I found some issues both with the NE10 library(fixed fft)
and with Linaro toolchain (armv8 intrinsics), the work

[RFC PATCH v1 0/4] Enable aarch64 intrinsics/Ne10
Hi All,
Since I continue to base my work on top of Jonathan's patch,
and my previous Ne10 fft/ifft/mdct_forward/backward patches,
I thought it would be better to just post all new patches
as a patch series. Please let me know if anyone disagrees
with this approach.

[RFC PATCH v1 0/5] aarch64: celt_pitch_xcorr: Fixed point series
Hi Timothy,
As I mentioned earlier [1], I now fixed compile issues
with fixed point and resubmitting the patch.
I also have new patch that does intrinsics optimizations
for celt_pitch_xcorr targetting aarch64.

For reference, you can use the Ne10 pre-built libraries

[PATCH 9/10] Vmi timer update.patch
Convert VMI timer to use clock events, making it properly able to use the NO_HZ
infrastructure. On UP systems, with no local APIC, we just continue to route
these events through the PIT. On systems with a local APIC, or SMP, we provide
a single source interrupt chip which creates the local timer IRQ. It actually
gets delivered by the APIC hardware, but we don't want to use the same local

Short time ago our Samba-Server crashed during normal use with low load.

can help me.
