[PATCH 00/22] new radeon info queries

[PATCH 00/22] new radeon info queries

[Alex Deucher]

This patch set implements a number of new
radeon info ioctl queries to support additional
profiling parameters for things like the GALLIUM
HUD.  It could also be used by apps like radeontop
to query the status registers, etc. without requiring
root privileges or needing asis specific knowledge
with respect to register BARs.

Alex Deucher (22):

Re: [PATCH 02/22] drm/radeon/dpm: add new callbacks to get the current sclk/mclk

[Christian König]

Might be a good idea to make that a bit more generic, e.g. add a 
get_current_clk callback and and a type (sclk, mclk, vclk, dclk, etc..) 
enum. But I can live with this approach as well.

Christian.

Yeah, I thought about that, but I'm not sure if there is a good way to
query that for certain clocks when dynamic clocking is enabled.  E.g.,
UVD on newer asics.

That's why I always favored using the PLL test registers. It can 
actually measure the clocks quite precisely if the reference clock 
(usually the PCI clock) is stable enough. And as far as I know can 
access any clock signal in the system, even the memory clock is 
measurable for each memory interface separately.

[PATCH 15/22] drm/radeon: add new callback for info ioctl register accessor

[Alex Deucher]

This adds a callback for each asic family to determine what
registers are allowed to be read back via the info ioctl.

The idea here is to allow usermode to query things like GPU status
registers or GPU harvest registers for profiling and determining
the gfx config.

[PATCH 22/22] drm/radeon: add support for read reg query from radeon info ioctl

[Alex Deucher]

This allows us to query certain registers from userspace
for profiling and harvest configuration.  E.g., it can
be used by the GALLIUM_HUD for profiling the status of
various gfx blocks.

Re: [PATCH 00/22] new radeon info queries

[Siavash Eliasi]

Hello, are these patches merged yet? or are they on the queue for Linux 
kernel 3.19?

And how they (shader/memory clocks) should be queried?

Thanks!

They are not merged yet.  There were some changes I wanted to make to
them before going upstream and I haven't had a chance to do it yet.

Tested-by: Marek Olšák <marek.olsak@amd.com>

Tested with: RV670, RV730, Redwood, Cayman, Cape Verde, Bonaire, Hawaii.

I have Mesa patches for the temperature, clocks, and GPU load. All
exposed via the Gallium HUD.
