source: trunk/tools/arch_info/genarch.py @ 425

Last change on this file since 425 was 279, checked in by alain, 5 years ago

1) Introduce independant command fields for the various devices in the thread descriptor.
2) Introduce a new dev_pic_enable_ipi() function in the generic PIC device
3) Fix two bugs identified by Maxime in the scheduler initialisation, and in the sched_select().
4) fix several bugs in the TSAR hal_kentry.S.
5) Introduce a third kgiet segment (besides kdata and kcode) in the TSAR bootloader.

9# This python script generates the "arch_info.bin" file required by the ALMOS-MK
10# operating system bootloader and describing the target hardware architecture.
11# It uses an architecture specific, python script that must be called "arch_info.py".
12#
13# The source directory containing the "arch_info.py" file and the destination directory
14# to store the "arch_info.bin" file are defined by parameters on the command line:
15#  --arch=string     : path to directory containing the "arch_info.py" file
16#  --bin=string      : path to directory store the "arch_info.bin" file
17#
18# As the target architecture is generic, the following hardware parameters can be
19# defined on the command line:
20#  --x_size=int      : number of clusters in a row
21#  --y_size=int      : number of clusters in a column
22#  --nb_cores=int    : number of cores per cluster
23#  --nb_ttys=int     : number of TTY channels
24#  --nb_nics=int     : number of NIC channels
25#  --fbf_size=int    : frame buffer width & heigth
26#  --ioc_type=string : can be IOC_BDV , IOC_HBA , IOC_SDC , IOC_SPI
27#
28# The following parameters can be used to generate the optional "hard_config.h" file,
29# that is required to configurate the SystemC virtual prototype, and the "arch_info.xml"
30# file for debug.
31#  --hard=string     : path to directory to store the "hard_config.h" file
32#  --xml=string      : path to directory to store the "arch_info.xml" file
