Perseus alpha30 (06/01):
Internal and memory voltage control. This is the first and only working implementation out there. Memory interface voltage is exactly what it the name implies, the voltage on the chip-to-chip interface from the SoC to the memory chip. Internal voltage is the whole SoC voltage excluding CPU, GPU, and the MIF. This includes all auxiliary function blocks such as the ISP/Image signal processor, camera interfaces, I/O interfaces, display controller and the MFC/Multi function codec hardware video de-/en-coder.
- Internal voltage respectively memory voltage table is found in /sys/devices/cpu/busfreq/ as int_volt_table or mif_volt_table
- The frequencies are defined as OPP\'s (Operating performance points), internal frequency and memory frequency (And voltages) together as a pair form an OPP. If you want to change the voltages through the sysfs files, keep in mind how you change them. MIF voltages are stored independently with each OPP step. INT voltages are stored in respect of their frequency key.
- Default OPP steps are: 440220, 293220, 293176, 176176, 147147, 110110. The first three numbers represent the memory frequency, the other three the internal base frequency. For example 293220 means the memory interface is at 293MHz (586MHz DDR) and the internal frequency is 220MHz.
- The voltages in STweaks are sorted out through some magic and are frequency unique, I recommend using that for controlling them.
Busfreq logic control added into STweaks, this includes all the already available configurables in the stock kernel with added explanations and I supplemented it with a sampling rate parameter.
Sensorhub driver and firmware updated.
Touchscreen driver and firmware updated.
Replaced pegasusq\'s runqueue detection logic with a new more superiror and precise in-scheduler collection logic, I found that the real runqueues are much less than what was previously reported. This should help a lot with hotplugging.
Enabled AFTR by default since we are now running very often in single-core mode. Keep in mind this mode is WFI Idle + LPA + AFTR.
Fixed a kernel bug which was eating up randomness entropy. This is related to that whole seeder business - please don\'t use any of those fixes. I also disabled virtual addresss randomization and at the same time disabled entropy generation from the block layer, which should avoid I/O overheads.
I raised the LPA CPU idle target residency, and fixed a bug in the ABB control for voltages for 900 and 1000MHz. I suspect these two to be causes of the sudden reboots for Note 2 users, and may fix them.
