Hi, I have two pci drivers (1) full driver with all functionality, (2) Driver which subset of (1). Both drivers are working fine. Load/Unload at run time smoothly works when each of them are done

Hello everyone, noob here. I need an accurate timestamp counter for a UEFI_APPLICATION.currently i'm ussing MdePkg/Library/SecPeiDxeTimerLibCpu/SecPeiDxeTimerLibCpu.inf for the TimerLib but

Ask your firmware vendor, or build your stuff upon open source software that you can analyze yourself. Thanks Laszlo

Hi Laszlo, Thanks for replying. Right. I have updated it now. Prior to calling to above mentioned call, I do map two 16 bytes chunks for reading and current chunk where I get error is 128bytes

(1) For BusMasterRead, you should not use AllocateBuffer. AllocateBuffer is only needed for CommonBuffer operations. For BusMasterRead and BusMasterWrite, Map will handle bounce buffers

Hello Experts, Need your help to understand why is PciIO->Map is returning "EFI_OUT_OF_RESOURCES" in my Intel CRB DQ57TM (v2.31) but same driver works in other SuperMicro system ( v2.31 and v2.4). I
