2016-03-04MdeModulePkg/PciHostBridge: Don't assume resources are fully NonExistentRuiyu Ni
The patch removes the assumption that the resources claimed by root bridges should not exist. Because resources might have been added: 1. by platform modules either in PEI through resource HOB, or in DXE, before the PCI host bridge driver runs. 2. Resources claimed by different root bridges may overlap so that resource adding operation for latter root bridges may fail if we assume the resource should not exist. In real world, this patch is to fit OVMF platform needs because different root bridges in OVMF platform shares the same resources.

If the Tpl of the async I/O callback in ScsiDiskDxe is TPL_CALLBACK and Sub-task 1 (UnderRun) succeeds but Sub-task 2 (OverRun) fails with an invalid parameter, DiskIoDxe will wait indefinitely for the event created by ScsiDiskDxe of Sub-task 1 to signal.

According to the PCI spec, when software writes all-one to BAR for size probing, the value read back should be 0b1...10...0 after masking the BAR type bits. But in real world, it's possible that certain device returns 0b0...01...10...0 for MEM64 BAR size probing: some bits in the high 32bit may be 0. PciBus driver has the code to handle such case. However, it doesn't handle the case that the high 32bit is totally 0. The patch is to handle the special case.

2015-07-28MdeModulePkg/UfsPassThru: Fix wrong GLOBAL_REMOVE_IF_UNREFERENCED usageFeng Tian
GLOBAL_REMOVE_IF_UNREFERENCED means __declspec(selectany) for MS tool chain IA32/X64 build. According to MSDN, "selectany" would tell the compiler that the declared global data item (variable or object) is a pick-any COMDAT (a packaged function). At link time, if multiple definitions of a COMDAT are seen, the linker picks one and discards the rest. So we have to remove GLOBAL_REMOVE_IF_UNREFERENCED key word from two global variable's extern definitions of .h file as we have used this keyword in .c file, otherwise the MS tool chain would pick the definitions in .h file and treat it as uninitialized data to generate full-0 content for these two global variables.
