[Nouveau] [PATCH RFC 00/20] expose global performance counters
Hello, This series exposes global performance counters (PCOUNTER) to the userspace through the nvif interface by reworking most of the code related to the PM engine. This interface will allow the userspace to control and monitor complex hardware events like the proprietary driver already does, for example with CUPTI and PerfKit. For now, this series only exposes performance counters on NV50, but this is going to be pretty similar for other families. My plan is to submit more patches for Fermi and Kepler after this series will be reviewed. The code of this series can be found here: http://cgit.freedesktop.org/~hakzsam/nouveau/log/?h=nouveau_perfmon And the corresponding libdrm branch can be found here: http://cgit.freedesktop.org/~hakzsam/drm/log/?h=nouveau_perfmon A full example which exposes both compute and graphics hardware events on NV50 can be found here: http://cgit.freedesktop.org/~hakzsam/perfevent Most of the code will be implemented in mesa once the kernel interface is going to be upstream and stable. Below, you can find a summary of the series: Patches 1-2: fix a bug related to the PM engine context Patches 3-4: remove useless PMU signals and unused functions Patches 5-6: reorganize the nvif interface to expose more stuff Patches 7-11: expose PCOUNTER domains to the userspace Patches 12-14: implement concept of sources (ie. multiplexers) Patches 15-17: allow to monitor complex hardware events Patches 18: add compute/graphics signals/sources Patches 19-20: expose a software methods interface for controlling PM Feel free to make a review. Thanks in advance!

[Nouveau] [PATCH RFC 02/20] pm: fix a potential race condition when creating an engine context
There is always the possiblity that the ppm->context pointer would get partially updated and accidentally would equal ctx. This would allow two contexts to co-exist, which is not acceptable. Moving the test to the critical section takes care of this problem.

[Nouveau] [PATCH RFC 05/20] pm: reorganize the nvif interface
This commit introduces the NVIF_IOCTL_NEW_V0_PERFMON class which will be
used in order to query domains, signals and sources. This separates the
querying and the counting interface.

[Nouveau] [PATCH RFC 11/20] pm: allow to monitor hardware signal index 0x00
This signal index must be always allowed even if it's not clearly
defined in a domain in order to monitor a counter like 0x03020100
because it's the default value of signals.

[Nouveau] [PATCH RFC 12/20] pm: add concept of sources
From: Samuel Pitoiset <samuel.pitoisetœgmail.com>
A source (or multiplexer) is a tuple addr+mask+shift which allows to
control a block of signals. The maximum number of sources that a signal
can define is arbitrary limited to 8 and this should be large enough.
This patch allows to define multi-level of sources for a signal.
Each different sources are stored to a global list and will be exposed
to the userspace through the nvif interface in order to avoid conflicts.

[Nouveau] [PATCH RFC 15/20] pm: allow the userspace to schedule hardware counters
This adds a new method NVIF_PERFCTR_V0_INIT which starts a batch of
hardware counters for sampling. This will allow the userspace to start
a monitoring session using the INIT method and to stop it with SAMPLE,
for example before and after a frame is rendered.
This commit temporarily breaks nv_perfmon but this is going to be fixed
with the upcoming patch.

[Nouveau] [PATCH RFC 16/20] pm: allow to configure domains instead of simple counters
Configuring counters from the userspace require the kernel to handle some
logic related to performance counters. Basically, it has to find a free
slot to assign a counter, to handle extra counting modes like B4/B6 and it
must return and error when it can't configure a counter.
In my opinion, the kernel should not handle all of that logic but it
should only write the configuration sent by the userspace without
checking anything. In other words, it should overwrite the configuration
even if it's already counting and do not return any errors.
This patch allows the userspace to configure a domain instead of
separate counters. This has the advantage to move all of the logic to
the userspace.

[Nouveau] [PATCH RFC 18/20] pm/nv50: add compute and graphics signals/sources
These signals and sources have been reverse engineered from NVIDIA
PerfKit (Windows) and CUPTI (Linux), they will be used to build complex
hardware events from the userspace.
This commit also adds a new class for GT200.

[Nouveau] [PATCH RFC 05/20] pm: reorganize the nvif interface

Patches 19/20, I need to think about some more.> > Signed-off-by: Samuel Pitoiset <samuel.pitoiset at gmail.com> > --- > bin/nv_perfmon.c | 12 ++++++------ > drm/nouveau/include/nvif/class.h | 26 ++++++++++++++++---------- > drm/nouveau/include/nvif/ioctl.h | 5 +++-- > drm/nouveau/nvkm/engine/pm/base.c | 38 ++++++++++++++++++++++++++++++++------ > 4 files changed, 57 insertions(+), 24 deletions(-) > > diff --git a/bin/nv_perfmon.c b/bin/nv_perfmon.c > index a8c5838..30a3138 100644 > --- a/bin/nv_perfmon.c > +++ b/bin/nv_perfmon.c > @@ -600,7 +600,7 @@ main(int argc, char **argv) > const char *cfg = NULL;

To do this, you need to create PERFMON as a nvkm_parent instead of an nvkm_object, and have its parent.sclass contain PERFMON. This will perhaps look a bit yucky for the moment, but I'm working on making things cleaner so I'll fix it later. Feel free to ping me on IRC if you need a hand making the change though. I actually have a large patch series with the first part of this cleanup work queued up, but if you can make the above change first, I'll rebase my work on yours so you don't have to deal with that. Thanks, Ben.> -- > 2.4.2 > > _______________________________________________ > Nouveau mailing list > Nouveau at lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau
