From: Steve Reinhardt Date: Wed, 16 Mar 2005 05:40:48 +0000 (-0500) Subject: Enhancements to python config proxy class. X-Git-Tag: m5_1.0_tutorial~69^2~5^2~4 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c8538d6a7e2b58ebcbe567023c9e1c5a0c3ee5a6;p=gem5.git Enhancements to python config proxy class. python/m5/config.py: - Enhanced Proxy class now supports subscripting, e.g., parent.cpu[0] or even parent.cpu[0].icache. - Proxy also supports multiplication (e.g., parent.cycle * 3), though this feature has not been tested. - Subscript 0 works even on non-lists, so you can safely say cpu[0] and get the first cpu even if there's only one. - Changed name of proxy object from 'Super' to 'parent', and changed "wild card" notation from plain 'Super' to 'parent.any'. python/m5/objects/AlphaConsole.mpy: python/m5/objects/BaseCPU.mpy: python/m5/objects/BaseSystem.mpy: python/m5/objects/Device.mpy: python/m5/objects/Ethernet.mpy: python/m5/objects/Ide.mpy: python/m5/objects/IntrControl.mpy: python/m5/objects/Pci.mpy: python/m5/objects/PhysicalMemory.mpy: python/m5/objects/Platform.mpy: python/m5/objects/SimConsole.mpy: python/m5/objects/SimpleDisk.mpy: python/m5/objects/Tsunami.mpy: python/m5/objects/Uart.mpy: Change 'Super.foo' to 'parent.foo' (and 'Super' to 'parent.any'). --HG-- extra : convert_revision : f996d0a3366d5e3e60ae5973691148c3d7cd497d --- diff --git a/python/m5/config.py b/python/m5/config.py index 182acf393..e6ad5a0ba 100644 --- a/python/m5/config.py +++ b/python/m5/config.py @@ -139,25 +139,90 @@ class Singleton(type): ##################################################################### class Proxy(object): -
