This series proposes a framework to test the virtual ITS. This is based on Drew's v7 series [1]. The last patch tests several ITS commands (collection/device mapping, interrupt translation service entry creation and LPI trigger through INT command). At this point we don't use any external PCIe device to write into the GITS_TRANSLATER register. The bulk of the code derives from the ITS driver code so all the credit is due to Marc. Many other ITS commands could be tested. Also existing MMIO accesses could be enhanced into standalone tests. Current focus was to make it functional. The code deserves more cleanup with respect to cacheability attributes in general. Tested on Cavium ThunderX [2].
