Re: [edk2] location of OvmfVideo.rom file?
Hello Laszlo, Many thanks. The readme says the video is no longer being built. I simply ignored it and did the rest of the procedure on http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=How_to_run_OVMF#Run_QEMU_using_OVMF and I could get a UEFI shell. Oddly, the ls/dir command does not work. Other commands do work though. Thank you for the info.

I'll look into your suggestion on the other routine to get the path. Sometimes you get lucky. If you call a function in library A, and you have library B in your [LibraryClasses], and library B has library A in its [LibraryClasses], then your code will be linked against both library A and library B. So you won't get a linker error. But if library B didn't already depend on library A, then your module wouldn't be linked against library A, and you'd get an error. It's best to list in your .inf file all the library classes which your code calls directly. The rule of thumb is that if you include a library's header file (#include Library/SomeLib.h), you should list that library class in your [LibraryClasses].

[edk2] Locating a file in the file system
Hello Is there an example someplace for accessing a file in the filesystem? I would like to be able to read a file into a buffer as a simple exercise. I saw the earlier notes about doing this via stdlib/posix api calls. I figure there is a similar method to do this via uefi api. Later I want to be able to locate a .fv file for use by the firmware volume routines. On a related note, how do you folks find routines? I'm doing massive greps though the header files trying to find routines which have a similar name to what I am doing. I'm also using google to search but that is hit and miss. For example, google UEFI file open gives me results about opening a .efi file via explorer. That is not what I want to do. -- John F.

[edk2] DevicePathToStr
Hello I see some code which uses DevicePathToStr. When I do a grep on it, I see it a few include files. 1. IntelFrameworkModulePkg 2. OvmfPkg 3. SecruityPkg I am working with the NT32 emulator so I'm guessing that I don't need the ones from source 2 and 3. However, when I try to include the header file for #include Library/GenericBdsLib.h // DevicePathToStr from the IntelFrameworkModulePkg it fails to compile. I also noticed that there is a .c file in MdeModulePkg (PlatDriOverrideDxe.c) which uses this routine. I was thinking that maybe there is some other way to get access to it, but I don't know. I don't see it any other header files. Any advice on how to use this routine? -- John F. Davis 6 Kandes Court Durham, NC 27713 919-888-8358 独树一帜 -- Flow-based real-time traffic analytics software.

Hmm. That is what I did to begin with.
Here are my includes and my .inf.
Now, I am really puzzled. When I pasted the error from the build below, I
noticed the error is actually in the code I used as a model for this app.
How could this app cause the other app which used to build to fail?

Re: [edk2] DevicePathToStr
Hello Jaben, No I did not. Its odd. Sometimes you add packages and it seems to compile and link. Other times I have to add a library package. In this case, I added the GenericBdsLib in the [LibraryClasses] and now it links. Many thanks. I'll look into your suggestion on the other routine to get the path.

Hello Andrew, Thanks, I appreciate the pointer. FWIW, I have also learned based upon Bill Pauls previous Moo code sample, you don't need to put apps in packages. I was using the MdeModulePkg/Application/HelloWorld/ directory as a source. I got tired of having to stop the emulator each time I made a change to my code in order for it to build. Consquently, I learned you can do this: 1. Create you app at top level directory. ex. MyFindRom2/MyFindRom2.inf and .c 2. Add the .inf to Nt32Pkg/Nt32Pkg.dsc 3. Build all 4. Build run 5. Run app via MyFindRom2 6. Make change to app 7. Build app via build -m MyFindRom2\MyFindRom2.inf 8. return to emulator and run the new app without having to shutdown the emulator.

Hello John,
In the test above, a valid definition for UINT32 was found.
The proper header file is getting included. The error message
is because Microsoft Visual Studio 2010 does not fully support
the C99 language standard. Your code is using the C99 feature,
mixed declarations and code.
Microsoft support for the C99 language standard is work in
progress. While no Microsoft compiler fully supports C99,
Visual Studio 2013 does support mixed declarations and code.
Two solutions are possible: 1) Switch to Microsoft Visual
Studio 2013. 2) Avoid use of mixed declarations and code.
For example:
// fails with VS2010
UINT32 test1 (UINT32 a)
{
a++;
UINT32 b = 1;
return a + b;
}
// passes with VS2010
UINT32 test2 (UINT32 a)
{
UINT32 b = 1;
a++;
return a + b;
}
Thanks,
Scott

Re: [edk2] hello world application sample and beyond
Hello I got a few emails. Perhaps I should repose the question. I was reading the EDKII Coding Guidelines document on tianocore. In it, it says do not use int or char native types. Consquently, I was trying to use UINT32 and UNIT8 types. When I try to extend the HelloWorld sample application from the MdeModulePkg with simple type definitions as UINT32 it fails to compile. I am confused by the other sample main since it seems to be doing precisely what the coding guidelines say not to do. So, how do you setup your includes in your .c file and the .inf file to build code which uses UINT types?

The “emulator” is an OS application where there are drivers that abstract POSIX/Win32 APIs as hardware devices. For example on a Mac a 64-bit application can not map any memory 4G (hard to have a pointer bug you don’t notice porting from 32-bit). If you run a memmap command in the Shell you can generally find the ROM as it will have a MemMapIO type and the upper bit of the attribute will be set. Thanks, Andrew Fish PS The EFI memory map is not used to tell the OS about MMIO, it is just used to get virtual MMIO mapping for EFI runtime services. So at a minimum the variable services need an virtual mapping to make the EFI Variable services to work. Note there is no requirement that the EFI Variables are in the same device as the Firmware code, but it is a common implementation. For instance, dmem fff3c9e8 is a region where I believe I have a rom mapped, but that command will crash the emulator. -- John F.

Re: [edk2] can you use the emulator with dmem in the rom region?
Hello Andrew and others, I used Andrew's suggestion and set a debugger breakpoint in the emulator. The results are close to what I was looking for. Its 28 bytes off. If any of you could please take a look and tell me why, I would appreciate it.

[edk2] corrections questions Ch 2 EDK II Build Spec
Corrections: Section 2 - Under the second Note on page 2. - Repeated The the Section 2.5.2 - Shouldn't the title be Firmware Files or a Firmware File System Files In the text beneath it also says are combined into a Firmware File (FFS) but if you go back to Figure 1 It shows EFI Section Files combined into a single Firmware Filesystem File. Probably would not hurt to add this file extension to the graphic as (.FFS) like the (.FD) and (.FV) are shown. Also, in section 2.5.2 Table 3 it uses FFS in the defines but the description column describes them as Firmware File System files. Questions: Section 2.2 - Figure 1 - If you were to have column headings for the two columns/Stacks, the one on the left is Tools and the one on the right would be Layers, right? In this same picture, the second layer on right is a PE32/PE32+ files, the Firmware Image files is what? S-Records? Image as it appears in memory? Section 2.4 - Figure 6 - What is a Typical IPD FD Layout? I'm assuming its a more generic FD for ARM processors. Section 2.5.3 Firmware Volumes - Figure 11 . General FV Layout o What is the difference between the FV Name GUID in the optional FV Header and File System GUID the FV Header? I'm thinking that the File System GUID in the FV Header is a constant for all .FV files = EFI_FIRMWARE_FILE_SYSTEM2_GUID as shown in section 2.6.10.1. The struct in this section FV_INFO above that has FvName[MAX_PATH] does that correspond to the FV_NAME_GUID in the optional FV Header and is it a GUID corresponding to the FIle Name of the .FV file? -- John F.

Re: [edk2] Toolchain question...
Hello bill This might not help but once a long time ago I had built a driver using the ddk and a user stack using the SDK. Both of these were free. Later when I tried to integrate it with a larger component built using a devstudio app the app failed to use the use mode stack DLLs I had built with the SDK. Despite fiddling with compiler settings I could never get this to work. Once I switched my user stack to being built with the same version of devstuidio it all magically worked. I guess I'm thinking that edk2 wants to avoid a similar problem.

I noticed there's a DDK3790 option which allows you to build just with the WinDDK compilers directly (e.g. no Visual Studio needed). It happens I have an actual CD copy of this kit -- I ordered it from Microsoft (for free!) some years ago when it was still a current product and held onto it, so I installed it on my Win7 machine in my office and lo and behold everything worked as expected (including the Microsoft C compiler being exceptionally fascist). But I noticed that the descriptions for the VS2003, VS2005, VS2008, VS2010 and VS2012 toolchain tags all say they require the WinDDK as well, e.g.: # VS2012 -win32- Requires: # Microsoft Visual Studio 2012 Professional Edition # Microsoft Windows Server 2003 Driver Development Kit (Microsoft WINDDK) version 3790.1830 My question is: what's the dependency that forces this requirement? It doesn't look as if the definitions in tools_def.txt cause the DDK tools to be used when one of the Visual Studio toolchain tags is selected, but I could be wrong. The reason I ask is that the WinDDK is obsolete and while you can still download it for free from Microsoft if you hunt for it, it seems the Windows Driver Kit 7.1 has taken its place.

[edk2] minnowboard and duet
Hello As I am looking through the EDKII workspace, I am wondering where is the port for minnowboard? I saw a video from an Intel guy on youtube and it mentioned the minnowboard as a atom based board which could be used as a cheap UEFI reference development kit. This sounds like a good deal for the UEFI support alone. The tunnelmountain kits are way out of my range for something to do in my personal time, but I'm wondering. I see BeagleBoard and Omap trees in the source but no minnowboard. Why is that? Does it not require its own seperate tree since it runs on the core workspace? Also, I see this tree for something called Duet. What is Duet? Is it another board port? Lastly, I see a lot of Ovmp discussion on the board lately. Is that a virtual UEFI bios port? I'm guessing, but not sure that you could build a .fv for it just as you build a .fv for the emulator and use it to boot a vm os. Is that the case? -- John F.

I just happened to be listening to this one while digging around in the code. https://www.youtube.com/watch?v=w6XbTGSGsy0list=PLisMMQz00Chydm-DeNZ0mgYbQj9DXMnzpindex=23 On Thu, Feb 6, 2014 at 12:36 PM, Blibbet blib...@gmail.com wrote: Use QEMU/OVMF, it gets more attention from Intel than DUET, which was an older tech. I don't think anyone at ARM cares about DUET, but theydo care about helping QEMU/OVMF. The UEFI Forum doesn't bother to update OVMF binaries to their download site, they're ancient. They presume you'll use the UDK/EDK2 to build your own fresh ones. If you don't want to build your own and need some existing binaries, look to the Linux community, for their research in learning how to work around SecureBoot. There are multiple fresh OVMFs there. Focus on the few Linux companies that're members of the UEFI Forum (Canonical, RedHat, Ubuntu), and their free distros, Fedora, Ubuntu, OpenSUSE. http://www.linux-kvm.org/page/OVMF http://en.opensuse.org/openSUSE:UEFI_Secure_boot_using_qemu-kvm https://fedoraproject.org/wiki/Testing_secureboot_with_KVM https://wiki.ubuntu.com/SecurityTeam/SecureBoot http://blog.hansenpartnership.com/uefi-secure-boot/ http://mjg59.dreamwidth.org/ If you really want to try and use DUET, look to external DUET extensions that make the TianoCore DUET release usable. There's this one, and one other I can't find at the moment: https://gitorious.org/tianocore_uefi_duet_builds If you're on a budget and can't get a Tunnel Mountain, I'd suggest an ARM dev board, over the Minnow. Minnowboard is good, but AFAIK you can't update the firmware, you have to wait for Intel to produce the binaries, so it's not that useful. If/when you can update your own firmware, then it'll become a lot more useful for EFI dev. Take a look at Linaro.org's ARM dev boards, and their fork of EDK2 for ARM. You can use their Ubuntu or Android binaries, and use their UEFI, in QEMU, or with live hardware. http://releases.linaro.org/latest/components/kernel/uefi-linaro https://wiki.linaro.org/ARM/UEFI https://wiki.linaro.org/LEG/Engineering/Kernel/UEFI/ https://launchpad.net/linaro-uefi https://snapshots.linaro.org/components/kernel/uefi-next https://snapshots.linaro.org/components/kernel/uefi/ https://wiki.linaro.org/LEG/Enginering/Kernel/UEFI/UEFI_Network_Booting If you're on a budget, ignore hardware and just use QEMU/OVMF.

[edk2] How do I quickly determine info such as what is difference between .efi and .ifi files?
Hello I notice that there are many file types in the edkII build workspace. I notice the workspace also contains files like .efi and .ifi. Besides knowing these are both PE files by examining them with a hex editor its not easy for me to find what the difference in these files are. From the EDK II Build Spec in chapter 10 it has some info on the file types by extension, but when I look at the UEFI specs I don't see anything which jumps out. For instance I the tables in Chapter 10 say that .efi o Is an input to GenFds. o Is an input to ImageGen I know there is a _EFI_FILE Structure Protocol which seems to be a file handle for accessing files on the EFI Partition. I'm guessing its kind of like a FILE handle for regular user mode file I/O. I also know that in the shell, whn you hit F8 and do dir you see a bunch of .efi files. Some of the files are xxx.efi and others are xxxDxe.efi. I thought the xxx.efi form would be applications since the Hello program I made from the Beyond Bios book makes a Hello.efi. The hello.efi program can be run by simply saying Hello, but the others like Cpu.efi or Cpu can not. I was thinking it would be something like cpuinfo in linux. As far as the xxxDxe.efi files, I'm pretty sure they are drivers since they correspond to the output of the drivers command. I don't know what the difference between a dxe driver and dxe application other than one might be an installer for a driver. Anyway, I notice that you can load and unload drivers in the shell. Odd that you can load a driver multiple times. Its also odd that if you load a driver it will show up in drivers output as \/ArpDxe.efi instead of ArpDxe as it is when loaded at boot. Also load Cpu.efi will crash the emulator. TLDR. Where in the UEFI spec is the pointer to all the different file types? .efi, .ifi, What is difference between drivers, driver applications? -- John F.

[edk2] pcd, fd and loading option roms/firmware at runtime
Hello In the EDK II build spec, Chapter 10 on Post-Build ImageGen Stage - Flash Images, it mentions PCD's (Some of the PCD's defined...) and FD (.. combined into FD image files..). What are these files? The glossary has PCD defined as a Platform Configuration Database, but I thought there would only be one Platform Configuration Database. Why the plural s? The work flow diagram in Figure 22 shows a .FD file as a Full Firmware Image. I notice there are NT32.fd and FVRECOVERY.Fv files of similar size in the NT32IA32/DEBUG_VSxx/FV directory. What is the difference in these two files? Only thing I can tell based upon a hex editor is that the strings which are in common are at different addresses and that the .fd file is used by the emulator as a firmware volume. From the description file: gEfiNt32PkgTokenSpaceGuid.PcdWinNtFirmwareVolume|L..\\Fv\\Nt32.fd Lastly, is there anyway to load firmware in the emulator at runtime and dump it? From the shell book, I can see you can load drivers but I haven't found anything on .fv files yet. -- John F.

[edk2] Fwd: EFI OS Loaders and Beyond BIOS book
I looked at that code in the EFI Toolkit. It looks like it is similar code to the OS Loader shown in the book except it uses stdlib. Thanks for the pointer, Vincent. This prompts a few more questions. It appears this code has been superseded by the EADK. Other than the stdlibinternals code all these components in EADK have been duplicated in the EDK2. Is that simply to prevent people from using the internals part? Also it looks like some of the utils which are in EFI Toolkit are in the EDK2 but not in EADK, like ramdisk, Edit, ping, etc. Why are some separated into EADK and others not? -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.

Yeah, I don't think this code will build. I understand what you guys were
telling me about it being a higher abstraction. Kind of like programming in
Xt versus programming in Motif but when I try to massage it into building
it does not work. It complains about not being able to find efi.h. I did
a search on efi.h the ones I found are commented out of the Nt32Pkg build
