rpiwav

BCM2836/BCM2711

Working

The audio driver (rpiwav.sys) uses the PWM driver (bcm2836pwm.sys) exclusively. rpiwav.sys sends PCM audio packets to bmc2836pwm.sys to modulate and output over the right and left channels resulting in a stereo audio output.

BCM283x Mini UART driver.
This is a Windows 10 device driver for the Broadcom proprietary version of the 16550 UART, available on the Pi 2 and 3. Due to lack of certain features present in the standard 16550 UART, the Broadcom version is called miniUart.

dsdtpatch

DSDT Patch:

1. changes the _HIDs of the

• PL011 controller to BCM2887

• XHCI controller to RPI0D10

    so Windows won't install the incompatible inbox drivers instead of our own versions. This is not necessary if the drivers are properly signed.

1. fixes the PWM definition and adds an analog audio device

2. adds dummy HDMI controller and digital audio devices
