SK-AM64: ti-sci error on CLKID 135

Part Number: SK-AM64

Hello,

Setting A53s clock using clkid 137 and clkid 136 works, but ti-sci generates an error when using clkid 135 which is unexpected (AM62x seems to accept addressing this clkid), this can be reproduced by using k3config:

k3conf set clock 137 0 xxx; k3conf set clock 136 0 xxx & k3conf set clock 135 0 xxx

I realize that the core cluster is using a single clock (clkid 137) but for consistency I believe this should be fixed where setting clkid 135 shouldn't return an error.

Thank you for considering this.

Hello,
Thanks for your e2e post, but I don't think there's an issue or inconsistency.

1. On AM64x
software-dl.ti.com/.../devices.html
135 AM64X_DEV_A53SS0_CORE_0
136 AM64X_DEV_A53SS0_CORE_1
137 AM64X_DEV_A53SS0

software-dl.ti.com/.../clocks.html

There's a sample log on how to modify "AM64X_DEV_A53SS0" clock from 1GHz to 800MHz with "k3conf" in the referenced e2e.

138 AM62X_DEV_A53SS0_CORE_3

I'm attaching a sample log on how to modify "AM62X_DEV_A53SS0" clock from 1.4GHz to 1.0GHz with "k3conf".

Best,

Hello,

Yes I agree on the above. My concern is that we can adjust the A53s clock using clk ID 136, but not with ID 135 (I know that the parent clock for both is 137). See log below:

So I should expect the same behavior from TISCI if I use CLK ID 135 or CLKID 136, but as you can see, CLKID 135 generates an error on AM64x (you could also check using CLKID 135 on AM62x to see if it generates an "Invalid clock arguments").

Thank you.

Hello Mehdi,
I tested on AM62x, and able to modify the clustered A53SS0 core frequency as shown in the log.
In fact, the frequency change would apply to all 4-cores in one TISCI API "TISCI_MSG_SET_CLOCK" call using any of following IDs.
135 AM62X_DEV_A53SS0_CORE_0
136 AM62X_DEV_A53SS0_CORE_1
137 AM62X_DEV_A53SS0_CORE_2
138 AM62X_DEV_A53SS0_CORE_3

166 AM62X_DEV_A53SS0

Let me look into the test case you reported on AM64x, ang get back to you...
Best,
-Hong

Hello,

Thank you for testing on AM62x, that is indeed the expected behavior. But there is a problem on AM64x, please confirm. I hope we can fix this in the next TISCI version.

Thank you.
