Lets have a look at trace from blob (GC3000):
0x000b000b, /* [10080] NTE.SAMPLER[0].SIZE := WIDTH=11,HEIGHT=11 */
0x2001b86e, /* [10100] NTE.SAMPLER[0].LOG_SIZE := WIDTH=3.437500,HEIGHT=3.437500,ASTC=0,INT_FILTER=1,SRGB=0 */
If we ignore the WIDTH and HEIGHT outputs and only look at the raw value (0x2001b86e) we can see that 0x6e is used for WIDTH and HEIGHT.
Lets have a look at an other texutre size 180x180:
0x00b400b4, /* [10080] NTE.SAMPLER[0].SIZE := WIDTH=180,HEIGHT=180 */
0x2003bcef, /* [10100] NTE.SAMPLER[0].LOG_SIZE := WIDTH=7.468750,HEIGHT=7.468750,ASTC=0,INT_FILTER=1,SRGB=0 */
Lets use the same test on a different GPU that uses texture descriptors (GC7000):
[44] SIZE: 0x000b000b WIDTH=11,HEIGHT=11
...
[74] LOG_SIZE_EXT: 0x03750375 WIDTH=3.457031,HEIGHT=3.457031
If we ignore the WIDTH and HEIGHT outputs and only look at the raw value (0x03750375) we can see that 0x375 is used for WIDTH and HEIGHT.
Lets have a look at an other texutre size 180x180:
[44] SIZE: 0x00b400b4 WIDTH=180,HEIGHT=180
..
[74] LOG_SIZE_EXT: 0x077d077d WIDTH=7.488281,HEIGHT=7.488281
etnaviv creates the following values for the two texture sizes:
11 -> 0x6f
180 -> 0xf0
Lets switch to U_FIXED(..) which results in equal values.
