[PATCH v6 1/6] media: dvb-frontends: tda10048: Make the range of z explicit.

[Ricardo Ribalda]

The datasheet recommends 55MHz frequency sampling, with a max of 69 MHz.
(Kudos to Kosta Stefanov for the calculations).

Replace z with a 32 bit uint, and make the range of the variable
explicit.

Found by cocci:

[PATCH v6 2/6] media: venus: vdec: Clamp parm smaller than 1fps and bigger than 240.

[Ricardo Ribalda]

The driver uses "whole" fps in all its calculations (e.g. in
load_per_instance()). Those calculation expect an fps bigger than 1, and
not big enough to overflow.

Clamp the value if the user provides a parm that will result in an invalid
fps.

This logic changes the actual fps from client. Consider a regular encode usecase
from client setting an fps as 30. The "max(USEC_PER_SEC, us_per_frame)" would
override it to USEC_PER_SEC and then the subsequent logic would eventually make
fps to 1.
Please make it conditional to handle the 0 fps case, i guess that the objective
in above code, something like below
if (!us_per_frame)
  us_per_frame = USEC_PER_SEC;

You are correct. Thanks for catching it!

I think I prefer:
us_per_frame = clamp(us_per_frame, 1, USEC_PER_SEC);

The driver uses "whole" fps in all its calculations (e.g. in
load_per_instance()). Those calculation expect an fps bigger than 1, and
not big enough to overflow.

Clamp the parm if the user provides a value that will result in an invalid
fps.

Same comment[1] made on 2/6 patch is applicable here as well.

[PATCH v6 4/6] media: venus: Remove timeperframe from inst

[Ricardo Ribalda]

The driver only cares about whole fps. We can infer the timeperframe
from the fps field. Remove the redundant field.

[PATCH v6 5/6] media: venus: venc: Make the range of us_per_frame explicit

[Ricardo Ribalda]

Fps bigger than 0.000232829 fps, this fits in a 32 bit us_per_frame.
There is no need to do a 64 bit division here.

Also, the driver only works with whole fps.

Found with cocci:
