Revision 82c99f7a81f28f8c1be5f701c8377d14c4075b10 authored by Harry Pan on 24 April 2019, 14:50:33 UTC, committed by Ingo Molnar on 25 April 2019, 06:59:31 UTC
Kaby Lake (and Coffee Lake) has PC8/PC9/PC10 residency counters.

This patch updates the list of Kaby/Coffee Lake PMU event counters
from the snb_cstates[] list of events to the hswult_cstates[]
list of events, which keeps all previously supported events and
also adds the PKG_C8, PKG_C9 and PKG_C10 residency counters.

This allows user space tools to profile them through the perf interface.

===================================================================
A driver for a selfmade cheap BT8xx based PCI GPIO-card (bt8xxgpio)
===================================================================

For advanced documentation, see http://www.bu3sch.de/btgpio.php

A generic digital 24-port PCI GPIO card can be built out of an ordinary
Brooktree bt848, bt849, bt878 or bt879 based analog TV tuner card. The
Brooktree chip is used in old analog Hauppauge WinTV PCI cards. You can easily
find them used for low prices on the net.

The bt8xx chip does have 24 digital GPIO ports.
These ports are accessible via 24 pins on the SMD chip package.


How to physically access the GPIO pins
======================================

The are several ways to access these pins. One might unsolder the whole chip
and put it on a custom PCI board, or one might only unsolder each individual
GPIO pin and solder that to some tiny wire. As the chip package really is tiny
there are some advanced soldering skills needed in any case.

The physical pinouts are drawn in the following ASCII art.
The GPIO pins are marked with G00-G23::
