10	help
11	  This option enables support for the Sony PS3 game console
12	  and other platforms using the PS3 hypervisor.  Enabling this
13	  option will allow building otheros.bld, a kernel image suitable
14	  for programming into flash memory, and vmlinux, a kernel image
15	  suitable for loading via kexec.

20config PS3_ADVANCED
21	depends on PPC_PS3
22	bool "PS3 Advanced configuration options"
23	help
24	  This gives you access to some advanced options for the PS3. The
25	  defaults should be fine for most users, but these options may make
26	  it possible to better control the kernel configuration if you know
27	  what you are doing.
28
29	  Note that the answer to this question won't directly affect the
30	  kernel: saying N will just cause the configurator to skip all
31	  the questions about these options.
32
33	  Most users should say N to this question.

35config PS3_HTAB_SIZE
36	depends on PPC_PS3
37	int "PS3 Platform pagetable size" if PS3_ADVANCED
38	range 18 20
39	default 20
40	help
41	  This option is only for experts who may have the desire to fine
42	  tune the pagetable size on their system.  The value here is
43	  expressed as the log2 of the page table size.  Valid values are
44	  18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.
45
46	  If unsure, choose the default (20) with the confidence that your
47	  system will have optimal runtime performance.

49config PS3_DYNAMIC_DMA
50	depends on PPC_PS3
51	bool "PS3 Platform dynamic DMA page table management"
52	help
53	  This option will enable kernel support to take advantage of the
54	  per device dynamic DMA page table management provided by the Cell
55	  processor's IO Controller.  This support incurs some runtime
56	  overhead and also slightly increases kernel memory usage.  The
57	  current implementation should be considered experimental.
58
59	  This support is mainly for Linux kernel development.  If unsure,
60	  say N.

71	help
72	  Include support for the PS3 AV Settings driver.
73
74	  This support is required for PS3 graphics and sound. In
75	  general, all users will say Y or M.

83	  Include support for the PS3 System Manager.
84
85	  This support is required for PS3 system control.  In
86	  general, all users will say Y or M.
87
88config PS3_REPOSITORY_WRITE
89	bool "PS3 Repository write support" if PS3_ADVANCED
90	depends on PPC_PS3
91	help
92	  Enables support for writing to the PS3 System Repository.
93
94	  This support is intended for bootloaders that need to store data
95	  in the repository for later boot stages.
96
97	  If in doubt, say N here and reduce the size of the kernel by a
98	  small amount.

109	  Include support for the PS3 Disk Storage.

119	  Include support for the PS3 ROM Storage.
120
121	  This support is required to access the PS3 BD/DVD/CD-ROM drive.
122	  In general, all users will say Y or M.
123	  Also make sure to say Y or M to "SCSI CDROM support" later.
124
125config PS3_FLASH
126	tristate "PS3 FLASH ROM Storage Driver"
127	depends on PPC_PS3
128	select PS3_STORAGE
129	help
130	  Include support for the PS3 FLASH ROM Storage.
131
132	  This support is required to access the PS3 FLASH ROM, which
133	  contains the boot loader and some boot options.
134	  In general, PS3 OtherOS users will say Y or M.
135
136	  As this driver needs a fixed buffer of 256 KiB of memory, it can
137	  be disabled on the kernel command line using "ps3flash=off", to
138	  not allocate this fixed buffer.
139
140config PS3_VRAM
141	tristate "PS3 Video RAM Storage Driver"
142	depends on FB_PS3=y && BLOCK && m

144	  This driver allows you to use excess PS3 video RAM as volatile
145	  storage or system swap.

151	  Include support for the PS3 Logical Performance Monitor.
152
153	  This support is required to use the logical performance monitor
154	  of the PS3's LV1 hypervisor.
155
156	  If you intend to use the advanced performance monitoring and
157	  profiling support of the Cell processor with programs like
158	  oprofile and perfmon2, then say Y or M, otherwise say N.
159
160config PS3GELIC_UDBG
161	bool "PS3 udbg output via UDP broadcasts on Ethernet"
162	depends on PPC_PS3
163	help
164	  Enables udbg early debugging output by sending broadcast UDP
165	  via the Ethernet port (UDP port number 18194).
166
167	  This driver uses a trivial implementation and is independent
168	  from the main PS3 gelic network driver.
169
170	  If in doubt, say N here.
