The gather filter is a feature present on Tegra124 and newer where the hardware prevents GATHERed command buffers from executing commands normally reserved for the CDMA pushbuffer which is maintained by the kernel driver. This commit enables the gather filter on all supporting hardware.

* Function naming determines intended use:
|
|
*
|
|
* <x>_r(void) : Returns the offset for register <x>.
|
|
*
|
|
* <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
|
|
*
|
|
* <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
|
|
*
|
|
* <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
|
|
* and masked to place it at field <y> of register <x>. This value
|
|
* can be |'d with others to produce a full register value for
|
|
* register <x>.
|
|
*
|
|
* <x>_<y>_m(void) : Returns a mask for field <y> of register <x>. This
|
|
* value can be ~'d and then &'d to clear the value of field <y> for
|
|
* register <x>.
|
|
*
|
|
* <x>_<y>_<z>_f(void) : Returns the constant value <z> after being shifted
|
|
* to place it at field <y> of register <x>. This value can be |'d
|
|
* with others to produce a full register value for <x>.
|
|
*
|
|
* <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register
|
|
* <x> value 'r' after being shifted to place its LSB at bit 0.
|
|
* This value is suitable for direct comparison with other unshifted
|
|
* values appropriate for use in field <y> of register <x>.
|
|
*
|
|
* <x>_<y>_<z>_v(void) : Returns the constant value for <z> defined for
|
|
* field <y> of register <x>. This value is suitable for direct
|
|
* comparison with unshifted values appropriate for use in field <y>
|
|
* of register <x>.
