Re: [edk2] ifconfig command issue in edk2

Thanks Jiaxin!

Shell> ifconfig -s eth0 static 192.168.112 ifconfig -s eth0 static 
Shell> 192.169 con
'con' is not recognized as an internal or external command, operable program, 
or script file.

These were actually not the issues.

I have just quoted some examples, where we give incomplete parameters to 
ifconfig, still it doesn't hang.

Thanks and Regards,

Hi Shaveta,

We will try to reproduce the ASSERT issue at first. We will investigate how to 
fix it as soon as we can reproduce this, or back to you once we fail to 
reproduce.

For below one, it seems you split the ifconfig command to two parts, and shell 
does not recognize the second part as 'con' is not a command.

Shell> ifconfig -s eth0 static 192.168.112 ifconfig -s eth0 static 
Shell> 192.169 con
'con' is not recognized as an internal or external command, operable program,

Hi,

I am observing one issue while using "ifconfig" command.

When ifconfig command is used with incomplete parameters like below, it hangs 
the system by throwing an ASSERT:

Shell> ifconfig -s eth0 static 192.168.2.142
ASSERT 
/home/jenkins/ci/sdk/sdk-ls1043a/ls1043ardb/ls1043a-uefi/MdePkg/Library/BaseLib/String.c(173):
 ((UINTN) String & 0x0001) == 0


Whereas in some other cases, it simply returns to prompt:
Shell> ifconfig -s eth0 static 192.168.112 ifconfig -s eth0 static 
Shell> 192.169 con
'con' is not recognized as an internal or external command, operable program, 
or script file.
Shell>


Is this some known issue or any pointer why is this happening?

Hi Ye Ting

Ping issue is resolved now.

I found in some old edk2 mails that it was some issue in Ping command 
implementation(Snippet pasted below).
After making TxRing ready beforehand, this issue get resolved now.

But TFTP issue is the one, I am still facing, any pointers on that?

Thanks and Regards,

Snippet of that mail chain issue :

Re: [edk2] Missing Ping Reply
The reason that the reply is missing is because when the reply is received and 
"Ping6OnEchoReplyReceived" is called, it kicks out in the call to 
"Ping6MatchEchoReply". The reason that reply does not match because there is no 
entry in the TxList when reply is received. 
In the function "PingSendEchoRequest", the ICMP message is sent out first 
before the entry is inserted into TxList. The reply comes back before the call 
comes back from "Transmit" function of the IPV4 protocol.

Now I tested the shell command too, in my usual virtual network environment; it 
works fine for me.

Thanks
Laszlo

I Too faced compilation issues, so I picked up "Guid/NicIp4ConfigNvData.h" file 
from tianocore site
" 
http://sourceforge.net/p/tianocore/edk2/ci/2638c111076f9a49d4766ca5acbafa0eb7f66a18/tree/MdeModulePkg/Include/Guid/NicIp4ConfigNvData.h;
Copied it in Guid folder and my code compiled.

Is this the correct file to compile the code with?

Shaveta

No. Please pull the new commits; Jaben checked in the patch that fixes the 
build (on Windows at least, and I have a pending patch that fixes it with gcc 
too).

Thanks

Thanks Laszlo!

I am not working on windows, so will wait for the patch that you are going to 
send to fix this.

I had captured TCPDUMP during TFTP on server:

Hi,

I more point to add.

With the same server configuration, UBOOT bootloader is able to do tftp 
successfully whereas UEFI fails.

Hi Laszlo,

 What kind of " problematic DHCP or TFTP config "? What should be the right

I have tftp file on TFTP server  "/etc/xinetd.d/tftp"  as follows :

I frequently retest TFTP, and I just did it right now as well, on top of 
current master. It works fine. My test environment is a virtual network, where 
OVMF runs in a virtual machine, and DHCP and TFTP are configured by libvirt and 
served by dnsmasq. The edk2 PXE client downloads shim, then shim downloads grub 
(with the PXE Base Code protocol), then grub downloads the kernel and the 
initial ramdisk, for a networked linux installation.

I have encountered and/or investigated quite a few TFTP issues, and most of the 
time they have occurred due to problematic DHCP or TFTP config, or problems in 
UEFI applications, or lower level network driver implementations. (In several 
other cases though, people contributed edk2 fixes ultimately.)

Anyhow, the first thing to in such cases is to capture a detailed packet log 
with tcpdump or wireshark, and analyze the packets against the DHCP / TFTP 
server config, the DHCP / PXE specs, and the edk2 code. Usually (again, in my 
experience, although I don't claim to be an expert), the DHCP / TFTP server 
config, or -- possibly -- the network is the culprit.

Please capture some packets, and analyze them. Analyzing DHCP packets against 
the specs and the server config takes forever, but I've found it to be the only 
way. Good luck.

[edk2] TFTP issue, Ping 1st packet reply missing

2015-09-24 Thread Leekha Shaveta

Hi,

Tftp is also giving issues.

During tftp, as one of its step it calls " GetFileSize"
Which go through Mtftp4 protocol and calls " Mtftp4->GetInfo"

And this fails.

Any idea what is the issue with tftp command? Has anyone tested it successfully?

Thanks and Regards,
Shaveta

Is the above the mapping of MMIO or DMA ? Because AllocateBuffer/IoMap are all 
about DMA, not MMIO 

[Shaveta] It is MMIO mapping ...

Note that regarding the issue of non-1:1 mappings vs.
GetBarAttributes(), I have patches to fix that in the core by enabling us to 
use the mTranslationOffset field of the ACPI descriptor. I will be able to post 
these some time next week.


[Shaveta] What does those patches does?
As I my case also, CPU address 50_4000_ is being translated to PCI bus 
address 0x4000_  For memory transactions. So its also a case of non- 1:1 
mapping

For Mem.Read/Mem.Write I have added a translation offset.
For BARs programming also, do we need to handle it?

How have you handled it?

Well, it depends if the mapping you provided above is an MMIO mapping or a DMA 
mapping ... I to looks like MMIO to me in which case it has strictly nothing to 
do with IoMap/AllocateBuffer 

[Shaveta] then what kind of mapping IoMap function should do when PCI NIC card 
ask for this IoMap during its "ping" operation ??

Ben

That is platform dependent. These buffers are for doing DMA. On x86 normal 
memory just works, for ARM you needed an uncached buffer, and you have to do 
some cache management to maintain coherency. 

[Shaveta] yes, I am working on an ARM platform. On ARM, "AllocateBuffer" 
function should return uncached buffer area? 
>From where this area need to be allocated? I mean from system memory or from

DDR/DRAM is DDR_ATTRIBUTES_CACHED
PCI space is " ARM_MEMORY_REGION_ATTRIBUTE_DEVICE"

Re: [edk2] PCI and non-1:1 mapping of MMIO space (Doubt o PCI Root bridge IOMap and IoAllocateBuffer)

2015-09-12 Thread Leekha Shaveta

Hi

I was implementing  PCI RootBridgeIo protocol and have some doubts in "IoMap" 
and "AllocateBuffer" functions of this protocol.

In our platform, PCI space is starting form address 0x50__ (40 bit 
addressable)
And its mapping on PCI bus is like:
50__ => _ (32 bit)

>From where the "AllocateBuffer" function should allocate memory when asked by 
>any PCI device?
What is the meaning of "Allocates pages that are suitable for an 
EfiPciOperationBusMasterCommonBuffer or
   EfiPciOperationBusMasterCommonBuffer64 mapping"

How to manage mapping in "RootBridgeIoMap" function?

Thanks and Regards,
Shaveta

Hi, Ben & Andrew

The GetBarAttributes() returns a set of ACPI 2.0 resource descriptors that 
describe the current configuration of the BARs of the PCI controller.

What I understood is the returned value of GetBarAttributes() is a CPU address 
rather than a PCI address. From the view of PciIo, nobody needs to know/use 
Bar's PCI address.

Thanks
Feng

Unfortunately, I am not familiar with the details of ACPI, I only have a high 
level understanding of it. Our platforms have been Open Firmware based for as 
far as I've been involved with them and lately, we use C -generated flat 
device-tree along with a custom runtime firmwarealled a  OPAL).

At this point I'm not (yet) considering a move to ACPI. I'm doing a proof of 
concept ppc64 UEFI port to get a feel of the water temperature more than 
anything else (though I'll be happy to contribute things back once I get the 
appropriate legalese sorted internally to IBM).

Ok. Well, it will be needed even on non-1:1 systems, we will have similar 
requirements of the OS needing an early boot framebuffer etc...
and I suspect the desire to directly access BARs (at least prefetchable
ones) from the CPU isn't going away in other areas either.

So maybe we should try to address this. I'm trying to figure out how to join 
the appropriate working groups etc... so I can participate in the spec side 
discussion as well (which I'll need to do for other reasons anyway if we are 
ever going to officially defining the ppc64 ABI in the spec).

Cheers,
Ben.

[edk2] PCI Bus scanning

2015-08-11 Thread Leekha Shaveta

Hi,

During PCI bus scanning, my execution hanged at 
ProcessOptionRom (RootBridgeDev, Mem32Base, RootBridgeDev-RomSize);

So I am commented this, and it went well.

Will there be any difference in PCI networking tests (ping/ifconfig/tftp), if I 
keep this
ProcessOptionRom code commented?

Thanks and Regards,
Shaveta

Hi Shaveta,

The upper layer drivers since SNP are available for several years and validated

Sorry I don't know whether you can get the UEFI Intel E1000 NIC card driver. 
You may search the download center in Intel.com? Hope other guys in the mailing
