1 Information about PowerPC Sound support
2=====================================================================

5comments or corrections.

7Last Change: 6.16.99
8
9This just covers sound on the PReP and CHRP systems for now and later
10will contain information on the PowerMac's.
11
12Sound on PReP has been tested and is working with the PowerStack and IBM
13Power Series onboard sound systems which are based on the cs4231(2) chip.
14The sound options when doing the make config are a bit different from
15the default, though.
16
17The I/O base, irq and dma lines that you enter during the make config
18are ignored and are set when booting according to the machine type.
19This is so that one binary can be used for Motorola and IBM machines
20which use different values and isn't allowed by the driver, so things
21are hacked together in such a way as to allow this information to be
22set automatically on boot.
23
241. Motorola PowerStack PReP machines
25
26 Enable support for "Crystal CS4232 based (PnP) cards" and for the
27 Microsoft Sound System. The MSS isn't used, but some of the routines
28 that the CS4232 driver uses are in it.
29
30 Although the options you set are ignored and determined automatically
31 on boot these are included for information only:
32
33 (830) CS4232 audio I/O base 530, 604, E80 or F40
34 (10) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15
35 (6) CS4232 audio DMA 0, 1 or 3
36 (7) CS4232 second (duplex) DMA 0, 1 or 3
37
38 This will allow simultaneous record and playback, as 2 different dma
39 channels are used.
40
41 The sound will be all left channel and very low volume since the
42 auxiliary input isn't muted by default. I had the changes necessary
43 for this in the kernel but the sound driver maintainer didn't want
44 to include them since it wasn't common in other machines. To fix this
45 you need to mute it using a mixer utility of some sort (if you find one
46 please let me know) or by patching the driver yourself and recompiling.
47
48 There is a problem on the PowerStack 2's (PowerStack Pro's) using a
49 different irq/drq than the kernel expects. Unfortunately, I don't know
50 which irq/drq it is so if anyone knows please email me.
51
52 Midi is not supported since the cs4232 driver doesn't support midi yet.
53
542. IBM PowerPersonal PReP machines
55
56 I've only tested sound on the Power Personal Series of IBM workstations
57 so if you try it on others please let me know the result. I'm especially
58 interested in the 43p's sound system, which I know nothing about.
59
60 Enable support for "Crystal CS4232 based (PnP) cards" and for the
61 Microsoft Sound System. The MSS isn't used, but some of the routines
62 that the CS4232 driver uses are in it.
63
64 Although the options you set are ignored and determined automatically
65 on boot these are included for information only:
66
67 (530) CS4232 audio I/O base 530, 604, E80 or F40
68 (5) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15
69 (1) CS4232 audio DMA 0, 1 or 3
70 (7) CS4232 second (duplex) DMA 0, 1 or 3
71 (330) CS4232 MIDI I/O base 330, 370, 3B0 or 3F0
72 (9) CS4232 MIDI IRQ 5, 7, 9, 11, 12 or 15
73
74 This setup does _NOT_ allow for recording yet.
75
76 Midi is not supported since the cs4232 driver doesn't support midi yet.
77
782. IBM CHRP
79
80 I have only tested this on the 43P-150. Build the kernel with the cs4232
81 set as a module and load the module with irq=9 dma=1 dma2=2 io=0x550

1 Information about the Linux/PPC kernel images
2=====================================================================
3
4Please mail me (Cort Dougan, cort@fsmlabs.com) if you have questions,
5comments or corrections.
6
7This document is meant to answer several questions I've had about how
8the PReP system boots and how Linux/PPC interacts with that mechanism.
9It would be nice if we could have information on how other architectures
10boot here as well. If you have anything to contribute, please
11let me know.
12
13
141. PReP boot file
15
16 This is the file necessary to boot PReP systems from floppy or
17 hard drive. The firmware reads the PReP partition table entry
18 and will load the image accordingly.
19
20 To boot the zImage, copy it onto a floppy with dd if=zImage of=/dev/fd0h1440
21 or onto a PReP hard drive partition with dd if=zImage of=/dev/sda4
22 assuming you've created a PReP partition (type 0x41) with fdisk on
23 /dev/sda4.
24
25 The layout of the image format is:
26
27 0x0 +------------+
28 | | PReP partition table entry
29 | |
30 0x400 +------------+
31 | | Bootstrap program code + data
32 | |
33 | |
34 +------------+
35 | | compressed kernel, elf header removed
36 +------------+
37 | | initrd (if loaded)
38 +------------+
39 | | Elf section table for bootstrap program
40 +------------+
41
42
432. MBX boot file
44
45 The MBX boards can load an elf image, and relocate it to the
46 proper location in memory - it copies the image to the location it was
47 linked at.
