v41 v42 140 140 To reduce various synchronisation mechanisms, ALMOS-MKH uses IPIs (Inter Processor Interrupt) : Any kernel instance, running on any corein any cluster can send an IPI to any other core in the architecture, using a remote write access to the relevant register in the PIC infrastructure. An IPI is handled as a special interrupt by the target core, and simply forces a scheduling on the target core. 141 141 142 == H) Text terminals ==142 == H) Text Terminals == 143 143 144 144 The target hardware architectures generally provide a variable - but bounded - number of text terminals (called TXT channels in ALMOS-MKH). This NB_TXT_CHANNELS number is an hardware parameter defined in the ''arch_info.bin'' file. We describe here how ALMOS-MKH uses these terminals:
