| [728] | 10 | # This file contains a mapping generator for the "tsar_generic_iob" platform. |
|---|
| [724] | 11 | # This includes both the hardware architecture (clusters, processors, peripherals, |
|---|
| 12 | # physical space segmentation) and the mapping of all kernel objects (global vsegs). |
|---|
| 13 | # This platform includes 6 external peripherals, accessible through two IO_Bridge |
|---|
| [738] | 14 | # components located in cluster [0,0] and cluster [x_size-1, y_size-1]. |
|---|
| 15 | # Available peripherals are: TTY, BDV, FBF, ROM, NIC, CMA. |
|---|
| [724] | 16 | # |
|---|
| 17 | # The "constructor" parameters are: |
|---|
| 18 | # - x_size : number of clusters in a row |
|---|
| 19 | # - y_size : number of clusters in a column |
|---|
| 20 | # - nb_procs : number of processors per cluster |
|---|
| 21 | # |
|---|
| 22 | # The "hidden" platform parameters are: |
|---|
| 23 | # - nb_ttys : number of TTY channels |
|---|
| 24 | # - nb_nics : number of NIC channels |
|---|
| 25 | # - fbf_width : frame_buffer width = frame_buffer heigth |
|---|
| 26 | # - x_io : cluster_io x coordinate |
|---|
| 27 | # - y_io : cluster_io y coordinate |
|---|
| 28 | # - x_width : number of bits for x coordinate |
|---|
| 29 | # - y_width : number of bits for y coordinate |
|---|
| 30 | # - paddr_width : number of bits for physical address |
|---|
| 31 | # - irq_per_proc : number of input IRQs per processor |
|---|
| 32 | # - use_ramdisk : use a ramdisk when True |
|---|
| 33 | # - peri_increment : address increment for replicated peripherals |
