PROCESSOR INFORMATION

73   CPUINFO
74       The  cpuinfo  supplied  in  /proc/cpuinfo  is  not  always  usable   by
75       linux_logo.   In  the relevant sysinfo_x.c file there is a place to add
76       custom output formatting to "beautify" the cpuinfo.  For  instance  "K6
77       (166  - 266)" is parsed to "K6". Formats have been added for the K6 and
78       certain Cyrix microprocessors.
79
80       If the cpuinfo for your microprocessor generates ugly output, send  the
81       output  from  your  /proc/cpuinfo and a sample of how it should look to
82       the author.
83
84       Unfortunately the 2.0.x kernels don't know about newer  chips.   So  to
85       get  linux_logo  to  recognize your Pentium II and newer chips you must
86       find some piece of information in /proc/cpuinfo that distinguishes them
87       from a pentium pro, or upgrade to a 2.2.x or 2.3.x kernel.
88
89   FORMAT
90       The  format  string special sequences start with # (use ## to print #).
91       All other characters, except for \n,  are printed as is.

117       Notes:
118
119       ·   The letter after the # must be capitalized.
120
121       ·   Options not available are silently ignored.
122
123       ·   Megahertz only available on some platforms and newer kernels.
124
125       ·   See defaults.h on how to have #N report in non-english numbers.
126
127       ·   Plural [#S] gives nothing if there is 1 cpu, gives 's' otherwise.
128
129       ·   The "-y" and "-u" [display uptime and load  average]  command  line
130           options don't affect the output if a custom format is used.
131
132       The default banner format is:
133
134       "#O Version #V, Compiled #C\n \
135       #N #M#X#T Processor#S, #R RAM, #B Bogomips Total\n \
136       #H\n"
137
138       The  default  banner format displays the following on the author's com‐
139       puter:
140
141         Linux Version 2.2.0-pre5, Compiled #47 Fri Jan 8 10:37:09 EST 1999
142            One 188MHz AMD K6 Processor, 64M RAM, 374.37 Bogomips Total
143                                      deranged
144       Another example would be:
145
146       linux_logo -F "Redhat Linux 5.2\nKernel Version #V\n#U\n#L\n"
147
148       which would display:
149
150                                  Redhat Linux 5.2
151                              Kernel Version 2.2.0-pre5
152                              Uptime 11 hours 4 minutes
153                            Load average 0.00, 0.00, 0.00

DEBIAN

157       The Debian pre-packaged version of linux_logo includes the Debian  logo
158       in addition to the 'Classic' and 'Banner' logos. The Debian logo is the
159       default logo unless one of the other logos is specified on the  command
160       line.
161

CONFIG FILES

163       ~/.linux_logo  and /etc/linux_logo.conf can be filled with command line
164       options and will be parsed before the actual command line
