2018-11-28Better process implementation (#491)gdkchan
* Initial implementation of KProcess * Some improvements to the memory manager, implement back guest stack trace printing * Better GetInfo implementation, improve checking in some places with information from process capabilities * Allow the cpu to read/write from the correct memory locations for accesses crossing a page boundary * Change long -> ulong for address/size on memory related methods to avoid unnecessary casts * Attempt at implementing ldr:ro with new KProcess * Allow BSS with size 0 on ldr:ro * Add checking for memory block slab heap usage, return errors if full, exit gracefully * Use KMemoryBlockSize const from KMemoryManager * Allow all methods to read from non-contiguous locations * Fix for TransactParcelAuto * Address PR feedback, additionally fix some small issues related to the KIP loader and implement SVCs GetProcessId, GetProcessList, GetSystemInfo, CreatePort and ManageNamedPort * Fix wrong check for source pages count from page list on MapPhysicalMemory * Fix some issues with UnloadNro on ldr:ro

2018-08-15More flexible memory manager (#307)gdkchan
* Keep track mapped buffers with fixed offsets * Started rewriting the memory manager * Initial support for MapPhysicalMemory and UnmapPhysicalMemory, other tweaks * MapPhysicalMemory/UnmapPhysicalMemory support, other tweaks * Rebased * Optimize the map/unmap physical memory svcs * Integrate shared font support * Fix address space reserve alignment * Some fixes related to gpu memory mapping * Some cleanup * Only try uploading const buffers that are really used * Check if memory region is contiguous * Rebased * Add missing count increment on IsRegionModified * Check for reads/writes outside of the address space, optimize translation with a tail call
