* Harmony chipset driver |
EXPORT_NO_SYMBOLS; |
|
* |
|
|
* This is a sound driver for ASP's and Lasi's Harmony sound chip |
|
|
* and is unlikely to be used for anything other than on a HP PA-RISC. |
|
|
* |
|
|
* Harmony is found in HP 712s, 715/new and many other GSC based machines. |
|
|
* On older 715 machines you'll find the technically identical chip |
|
|
* called 'Vivace'. Both Harmony and Vicace are supported by this driver. |
|
|
* |
|
|
* this ALSA driver is based on OSS driver by: |

/* |
|
|
* Harmony chipset 'modus operandi'. |
|
|
* - This chipset is found in some HP 32bit workstations, like 712, or B132 class. |
|
|
* most of controls are done through registers. Register are found at a fixed offset |
|
|
* from the hard physical adress, given in struct dev by register_parisc_driver. |
|
|
* |
|
|
* Playback and recording use 4kb pages (dma or not, depending on the machine). |
|
|
* |
|
|
* Most of PCM playback & capture is done through interrupt. When harmony needs |
|
|
* a new buffer to put recorded data or read played PCM, it sends an interrupt. |
|
|
* Bits 2 and 10 of DSTATUS register are '1' when harmony needs respectively |
|
|
* a new page for recording and playing. |
|
|
* Interrupt are disabled/enabled by writing to bit 32 of DSTATUS. |
|
|
* Adresses of next page to be played is put in PNXTADD register, next page |
|
|
* to be recorded is put in RNXTADD. There is 2 read-only registers, PCURADD and |
|
|
* RCURADD that provides adress of current page. |
|
|
* |
|
|
* Harmony has no way to controll full duplex or half duplex mode. It means |
|
|
* that we always need to provide adresses of playback and capture data, even |
|
|
* when this is not needed. That's why we statically alloc one graveyard |
|
|
* buffer (to put recorded data in play-only mode) and a silence buffer. |
|
|
* |
|
|
* Bitrate, number of channels and data format are controlled with |
|
|
* the CNTL register. |
|
|
* |
|
|
* Mixer work is done through one register (GAINCTL). Only input gain, |
|
|
* output attenuation and general attenuation control is provided. There is |
|
|
* also controls for enabling/disabling internal speaker and line |
|
|
* input. |
|
|
* |
|
|
* Buffers used by this driver are all DMA consistent. Since harmony is |
|
|
* not "real" pci device, we use a fake struct pci_dev for |
|
|
* pci_alloc_consistent(). |
|
|
* (note that some machines -712 for ex.- don't implement DMA consistent |
|
|
* memory, so we will need to use kmalloc instead) |
