From 04846b5b8112e53b588038349b3e92b8485c1807 Mon Sep 17 00:00:00 2001 From: Hidetoshi Seto Date: Mon, 20 Apr 2009 10:54:52 +0900 Subject: PCI MSI: Remove unused/obsolete macros and definitions Impact: cleanup, spec compliance This patch does: - Remove unused msi/msix_enable/disable macros. User should use msi/msix_set_enable() functions instead. - Remove unused msix_mask/unmask/pending macros. These macros are useless because they are not based on any of the PCI Local Bus Specifications properly. It seems that they were written based on a draft of PCI spec, and that the draft was the MSI-X ECN that underwent membership review in September 2002. (* In the draft, the size of a entry in MSI-X table was 64bit, containing 32bit message data and DWORD aligned lower address plus a pending bit and a mask bit.(30+1+1bit) The higher address was placed in MSI-X capability structure and shared by all entries.) - Remove PCI_MSIX_FLAGS_BITMASK. This definition also come from the draft ECN.
