The existing fix for errata i940 causes a conflict for IPU2 which is
using timer 3 and 4. From arch/arm/boot/dts/dra7-ipu-dsp-common.dtsi:
&ipu2 {
mboxes = <&mailbox6 &mbox_ipu2_ipc3x>;
ti,timers = <&timer3>;
ti,watchdog-timers = <&timer4>, <&timer9>;
};
The conflict was noticed when booting mainline on the BeagleBoard X15
which has a TI AM5728 SoC:
remoteproc remoteproc1: 55020000.ipu is available
remoteproc remoteproc1: powering up 55020000.ipu
remoteproc remoteproc1: Booting fw image dra7-ipu2-fw.xem4
omap-rproc 55020000.ipu: could not get timer platform device
omap-rproc 55020000.ipu: omap_rproc_enable_timers failed: -19
remoteproc remoteproc1: can't start rproc 55020000.ipu: -19
This change modifies the errata fix to instead use timer 15 and 16 which
resolves the timer conflict.
It does not appear to introduce any latency regression. Results from
cyclictest with original errata fix using dmtimer 3 and 4:
# cyclictest --mlockall --smp --priority=80 --interval=200 --distance=0
policy: fifo: loadavg: 0.02 0.03 0.05

T: 1 ( 1450) P:80 I:200 C: 800301 Min: 0 Act: 12 Avg: 23 Max: 70
The results after the change to dmtimer 15 and 16:
# cyclictest --mlockall --smp --priority=80 --interval=200 --distance=0
policy: fifo: loadavg: 0.36 0.19 0.07

Gentle reminder, I don't see this in linux-next yet, was kinda expecting this
would be included in the fixes for 5.17.
Just want to make sure that the patch did not get lost in your mbox.

clocksource/drivers/timer-ti-dm: Fix regression from errata i940 fix
The existing fix for errata i940 causes a conflict for IPU2 which is
using timer 3 and 4. From arch/arm/boot/dts/dra7-ipu-dsp-common.dtsi:
&ipu2 {
mboxes = <&mailbox6 &mbox_ipu2_ipc3x>;
ti,timers = <&timer3>;
ti,watchdog-timers = <&timer4>, <&timer9>;
};
The conflict was noticed when booting mainline on the BeagleBoard X15
which has a TI AM5728 SoC:
remoteproc remoteproc1: 55020000.ipu is available
remoteproc remoteproc1: powering up 55020000.ipu
remoteproc remoteproc1: Booting fw image dra7-ipu2-fw.xem4
omap-rproc 55020000.ipu: could not get timer platform device
omap-rproc 55020000.ipu: omap_rproc_enable_timers failed: -19
remoteproc remoteproc1: can't start rproc 55020000.ipu: -19
This change modifies the errata fix to instead use timer 15 and 16 which
resolves the timer conflict.
It does not appear to introduce any latency regression. Results from
cyclictest with original errata fix using dmtimer 3 and 4:
# cyclictest --mlockall --smp --priority=80 --interval=200 --distance=0
policy: fifo: loadavg: 0.02 0.03 0.05

T: 1 ( 1450) P:80 I:200 C: 800301 Min: 0 Act: 12 Avg: 23 Max: 70
The results after the change to dmtimer 15 and 16:
