[edk2] SSH access on to UEFI shell
Hi Team, I would like to know is there any way to get UEFI shell remotely to my local setup over SSH/Telnet. I have spend hours for searching, Please help me if there any framework or EFI protocol support for this. Any sample code also helpful me to start Thanks In advance Prabin CA ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel

Re: [edk2] PerformancePkg on multiple platform -
Hi Andrew, I have already enabled that PCD in my DSC file, because of that its working in some platform. What I'm doing is building my DP.efi and DXE driver from that dsc file and testing it from UEFI shell. thanks for your help as well.

Hi Laszlo, Thank you for your valid input, Its really help full for me. I will look in the " A Tour Beyond BIOSImplementing Profiling in with EDK II" with your points. have a nice day.

[edk2] PerformancePkg on multiple platform
Hi Team, I’m new to uefi and edk. Currently I’m trying to get performance of my dxe driver using PerformancePkg of EDK source code. I’m using perf_start and perf_end T respected check points, it’s hot build and tested well in 2/3 platform. It’s giving proper response. But when I’m Checking with multiple platform, in some of platforms it’s not working and got hang in uefi she’ll itself. Please help me to resolve asap, it will be really helpful. ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
