Last change on this file since 295 was 295, checked in by alain, 10 years ago

Introducing a major release, to suppoort the tsar_generic_leti platform
and the various (external or internal) peripherals configurations.
The map.xml format has been modified, in order to support the new
vci_iopic componentand a new policy for peripherals initialisation.
The IRQs are nom described in the XICU and IOPIC components
(and not anymore in the processors).
To enforce this major change, the map.xml file signature changed:
The signature value must be: 0xDACE2014

This new release has been tested on the tsar_generic_leti platform
for the following mappings:

  • 4c_4p_sort_leti
  • 4c_4p_sort_leti_ext
  • 4c_4p_transpose_leti
  • 4c_4p_transpose_leti_ext
  • 4c_1p_four_leti_ext
  • Property svn:executable set to *

7// The MAPPING_INFO data structure, used by the GIET_VM kernel contains:
8//
9// 1) a description of a clusterized hardware architecture.
10// The number of cluster is variable (can be one). The number of processors
11// per cluster is variable (can be one). The number of peripherals per cluser
12// and coprocessor per cluster is variable. The number of physical memory
13// banks per cluster is variable.
14//
15// 2/ a description of the applications (called vspaces) to be - statically -
16// launched on the platform. The number of parallel tasks per application is
17// variable (can be one). Multi-Writer/Multi-Reader communication channels
18// betwwen tasks are supported. Each vspace contains a variable number
19// of virtual segments (called vsegs).
20//
21// 3/ the mapping directives: both tasks on processors, and software objects
22// (vobjs and vsegs) on the physical memory banks (called psegs).
23// and a variable number of tasks. The number of virtual space can be one.
24//
25// The mapping_info data structure is organised as the concatenation of
26// a fixed size header, and 11 variable size arrays:
27//
28// - mapping_cluster_t  cluster[] 
29// - mapping_pseg_t     pseg[]       
30// - mapping_vspace_t   vspace[] 
31// - mapping_vseg_t     vseg[]     
32// - mapping_vobj_t     vobj[]   
33// - mapping_task_t     task[] 
34// - mapping_proc_t     proc[] 
35// - mapping_irq_t      irq[]   
36// - mapping_coproc_t   coproc[]
37// - mapping_cp_port_t  cp_port[]
38// - mapping_periph_t   periph[]
39//
40// It is intended to be stored in memory in the seg_boot_mapping segment.
