I am trying to enable multiple MSI irq lines in a kernel module. I am operating in RC mode. The problem is when I call pci_enable_msi_block() it will not allocate more than 1 MSI. If I call pci_enable_msi_block(dev, 32) it will return 4 (which I assume should mean I can use 4 MSI). I then call pci_enable_msi_block(dev,4) and it returns 1.
Here is an output from $lspci -v after insmod Custom_module.ko but with only a successful enable of 1 MSI

How do I go about using more than 1 MSI. I can use JTAG to edit the Enable_MSI registers and then the EP can trigger the MSI, but there is no handler dedicated to these IRQs.

I have currently got a CENTOS7 guest inside windows 10 host and I am trying to install vagrant and Virtual box inside the CENTOS guest to create a kubernetes cluster for local development.
I have installed vagrant 2.1.1 and VirtualBox 5.2.12
When I am trying to
vagrant up
It says VT-X is not available.
I have turned on Virtualization in BIOS and I have checked windows features and HyperV is disabled/unchecked.
Also when I cat the /proc/cpuinfo , vmx is not in the flags

I would really appreciate any insight on how I can get this resolved.
You disabled hyper-v, this means that you are using alternative hypervisor(virtualbox?). I don't think that anything except hyper-v on windows supports nested virtualization.
You can give a try to hyper-v guest with centos(with enabled nested virtualization by command Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true) and run virtualbox with vagrant inside it.

It seems that the Virtual File System tries to read from some unknown-block:

Googling, no solutions were found.
Has somebody some idea on how to solve this? Where can we have a look? Which parameter to play with?
Finally I solved all the problems I had (running linux on Zybo with a custom hw in the Programmable Logic). Yes, because I am a beginner, I found different problems:
1) One of the problem was in the .dts: the part with eFuse was compleatly missing. Xilinx committed another version of the .dts with the problem fixed.
2) Another big problem was with the bitstream: at the beginning I wanted to program the PL on Zybo with a running linux using: cat bitstream.bit > /dev/xdevcfg. Of course this is compleatly possible (I tested it) as it is explaned in [this wiki-page][1]. Problem: if you have a custom HW in in FPGA you have also its description in the device-tree. The kernel tries to initialize all the periferics connected to the PS but, of course, the PL is not yet connected!! The solution is to download the bitstream before, including it in the boot.bif in order to generate the boot.bin in the right way:
image : {
[bootloader]fsbl.elf
bitstream.bit
u-boot.elf
devicetree.dtb
uramdisk.image.gz
uImage.bin // currently bootgen requires a file extension. this is just a renamed uImage
}
of course using: bootgen -image boot.bif -o i boot.bin.
There were other little problems and I will try to add a list in future editing-revision of this answer.
UPDATE:
to solve the problem described in the question, if there are no additional problems/errors, should be enough to add the bootargs the option rootdelay=3 (rootdelay — Time to delay before attempting to mount the root filesystem).
This can be necessary because u-boot tries to access the SD too fast and the SD is not ready yet.
You have it set to use the root filesystem on mmcblk0p2 - the second partition of your SD-card. If the filesystem is in fact placed there, you have to verify that the kernel has support for what the partition was formatted with (e.g. ext3).
Is this a prebuilt image or one you built yourself?
If you use the command petalinux-config before building, you can change settings for where to store the filesystem.
Btw, this is a very common problem so you should find lots of info if you use the right terms when you google it.
Introduction:
I am trying to "say" something to my virtual device ( I mean virtualbox). So first, I have to know I/O port or Memory address region.
So, let look at my lspci output:

Problem
So there are two region and I don't understand why there are two regions. I don't know
if device is memory-mapped or port-mapped? I don't understand how can I write bytes to my device. What address I should choose?

QEMU: Terminated
Here is my qemu boot script:
qemu-system-i386 \
-m 256M \
-kernel images/bzImage \
-append "root=/dev/sda rw console=ttyS0,115200" \
-hda images/rootfs.ext2 \
-boot c \
-localtime \
-net nic,vlan=0,macaddr="12:34:56:78:9a:bc" \
-net nic,vlan=0,macaddr="12:34:56:78:bc:de" \
-net tap,vlan=0,ifname=tap0,script=./qemu-ifup \
-nographic
I also tried the qemu_arm_versatile_defconfig with the same qemu boot
script, and it works very well, so I really can not understand what's
wrong, and any tips?
regards
Back in late 2011, we had problems with the IA32 CodeSourcery toolchain, but they should now be fixed.
Try to use:
root=/dev/sda1
in boot script as sda1 corresponds to the first partition of the sda.
Have you tried to disable SELinux as mentioned in this thread?? Perhaps it might fix it.
I need hardware information just as listed below which was generated using lshw in linux. I need a windows equivalent without a GUI more preferably like a code or dll which can be used to extract the information in the same tree like structure. Please note Wmi is not a suitable option as it does not give me empty slots while lshw does.

You can have a look at Microsoft's DevCon: The DevCon command-line utility functions as an alternative to Device Manager.
The source code for DevCon is also available in the Windows DDK (which is available from http://www.microsoft.com/whdc/devtools/ddk/default.mspx) under DDK root\Src\Setup\Devcon, along with documentation. The source code shows you how to use the various API in the SetupAPI.
I know that USBDeview is like lsusb on Windows. You can find it from http://www.nirsoft.net/ .
Perhaps one of Nirsoft's other software is helpful for your needs? Like Devmanview or Driverview?
If you prefer the tree view, then go into Device Manager (usually in System->Hardware). This will show you all the devices in your system. It's better than the command prompt in Ubuntu, although you might have to dig further than normal to find specifics like data width or channel modes.
An easier option is to go to the Piriform website, and pick up Speccy. I'd suggest the portable build, because it's more convenient, and besides, you'll only use it a few times.
Speccy is a real cool program that will detect almost anything you want to know. I've never had any inaccuracies, and this is my go-to tool for new hardware.
You have several options, please see my answer at SR SE.
DevCon.exe (CLI) which is available in sources from the github repo, or alternatively can be obtained from the Windows SDK, WDK (Windows Driver Kit) or EDWK.
USBview.exe (GUI) - available in same location as above. And described here.
listdevs.exe (CLI) - You can use some of the libusb based tools found in their github.
Some Example usages:
# Some useful devcon examples:
#devcon.exe classes # to list all available classes
#devcon.exe listclass net
#devcon.exe hwids =net
