4config PS3_ADVANCED
5	depends on PPC_PS3
6	bool "PS3 Advanced configuration options"
7	help
8	  This gives you access to some advanced options for the PS3. The
9	  defaults should be fine for most users, but these options may make
10	  it possible to better control the kernel configuration if you know
11	  what you are doing.
12
13	  Note that the answer to this question won't directly affect the
14	  kernel: saying N will just cause the configurator to skip all
15	  the questions about these options.
16
17	  Most users should say N to this question.

19config PS3_HTAB_SIZE
20	depends on PPC_PS3
21	int "PS3 Platform pagetable size" if PS3_ADVANCED
22	range 18 20
23	default 20
24	help
25	  This option is only for experts who may have the desire to fine
26	  tune the pagetable size on their system.  The value here is
27	  expressed as the log2 of the page table size.  Valid values are
28	  18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
29
30	  If unsure, choose the default (20) with the confidence that your
31	  system will have optimal runtime performance.
32
33config PS3_DYNAMIC_DMA
34	depends on PPC_PS3 && EXPERIMENTAL
35	bool "PS3 Platform dynamic DMA page table management"
36	default n
37	help
38	  This option will enable kernel support to take advantage of the
39	  per device dynamic DMA page table management provided by the Cell
40	  processor's IO Controller.  This support incurs some runtime
41	  overhead and also slightly increases kernel memory usage.  The
42	  current implementation should be considered experimental.
43
44	  This support is mainly for Linux kernel development.  If unsure,
45	  say N.
46
47config PS3_USE_LPAR_ADDR
48	depends on PPC_PS3 && EXPERIMENTAL
49	bool "PS3 use lpar address space"
50	default y
51	help
52	  This option is solely for experimentation by experts.  Disables
53	  translation of lpar addresses.  SPE support currently won't work
54	  without this set to y.
55
56	  If you have any doubt, choose the default y.
57
58config PS3_VUART
59	depends on PPC_PS3
60	bool "PS3 Virtual UART support" if PS3_ADVANCED
61	default y
62	help
63	  Include support for the PS3 Virtual UART.
64
65	  This support is required for several system services
66	  including the System Manager and AV Settings.  In
67	  general, all users will say Y.
68
69config PS3_PS3AV
70	tristate "PS3 AV settings driver" if PS3_ADVANCED
71	depends on PS3_VUART
72	default y
73	help
74	  Include support for the PS3 AV Settings driver.
75
76	  This support is required for graphics and sound. In
77	  general, all users will say Y or M.
78
79config PS3_SYS_MANAGER
80	bool "PS3 System Manager driver" if PS3_ADVANCED
81	depends on PS3_VUART
82	default y
83	help
84	  Include support for the PS3 System Manager.
85
86	  This support is required for system control.  In
87	  general, all users will say Y.
