67 comment "Archimedes/A5000 Implementations (select only ONE)"
72 Say Y to support the Acorn Archimedes.
74 The Acorn Archimedes was an personal computer based on an 8MHz ARM2
75 processor, released in 1987. It supported up to 16MB of RAM in
76 later models and floppy, harddisc, ethernet etc.
81 Say Y here to to support the Acorn A5000.
84 internal IDE disk and CD-ROM interface, serial and parallel port,
85 and the floppy drive. Note that on some A5000s the floppy is
86 plugged into the wrong socket on the motherboard.
89 bool "2MB physical memory (broken)"
91 Say Y here if your Archimedes or A5000 system has only 2MB of
92 memory, otherwise say N. The resulting kernel will not run on a
93 machine with 4MB of memory.
102 # Compressed boot loader in ROM. Yes, we really want to ask about
103 # TEXT and BSS so we preserve their values in the config files.
105 bool "Compressed boot loader in ROM/flash"
107 Say Y here if you intend to execute your compressed kernel image (zImage)
108 directly from ROM or flash. If unsure, say N.
110 config ZBOOT_ROM_TEXT
112 hex "Compressed ROM boot loader base address"
115 The base address for zImage. Unless you have special requirements, you
116 should not change this value.
120 hex "Compressed ROM boot loader BSS address"
123 The base address of 64KiB of read/write memory, which must be available
124 while the decompressor is running. Unless you have special requirements,
125 you should not change this value.
128 bool "Execute In Place (XIP) kernel image"
130 Select this option to create a kernel that can be programed into
133 comment "At least one math emulation must be selected"
136 tristate "NWFPE math emulation"
138 Say Y to include the NWFPE floating point emulator in the kernel.
139 This is necessary to run most binaries. Linux does not currently
140 support floating point hardware so you need to say Y here even if
141 your machine has an FPA or floating point co-processor podule.
143 It is also possible to say M to build the emulator as a module
144 (nwfpe) or indeed to leave it out altogether. However, unless you
145 know what you are doing this can easily render your machine
146 unbootable. Saying Y is the safe option.
148 You may say N here if you are going to load the Acorn FPEmulator
151 source "fs/Kconfig.binfmt"
154 bool "Preemptible Kernel (EXPERIMENTAL)"
155 depends on CPU_32 && EXPERIMENTAL
157 This option reduces the latency of the kernel when reacting to
158 real-time or interactive events by allowing a low priority process to
159 be preempted even if it is in kernel mode executing a system call.
160 This allows applications to run more reliably even when the system is
163 Say Y here if you are building a kernel for a desktop, embedded
164 or real-time system. Say N if you are unsure.
167 tristate "RISC OS personality"
170 Say Y here to include the kernel code necessary if you want to run
171 Acorn RISC OS/Arthur binaries under Linux. This code is still very
172 experimental; if this sounds frightening, say N and sleep in peace.
173 You can also say M here to compile this support as a module (which
174 will be called arthur).
177 string "Default kernel command string"
180 On some architectures (EBSA110 and CATS), there is currently no way
181 for the boot loader to pass arguments to the kernel. For these
182 architectures, you should supply some command-line options at build
183 time by entering them here. As a minimum, you should specify the
184 memory size and the root device (e.g., mem=64M root=/dev/nfs).
