I want to run a project that communicates with a USB device using. I already have it on Linux, and it works great there, so I want to run it on Windows with. I installed libusb for Windows and libusb in Cygwin, then tried to compile it.

It turns out that you need pciutils, unlike on Linux in which it's really easy to get it. Download Free 365 Casio Manual Pcrb here. In Cygwin it's a problem.

After overcoming some difficulties I managed to get further with my purpose of compiling pciutil in the Cygwin environment. I follwed these steps: • Download winio package for Windows and went to Winio Binaries and copied winio32.dll and winio32.sys to the pciutil directory. • Copy config.h/mk from./win32 to./lib • Go to. Lib i386-io-winodws.h and change line 39 to 'lib = LoadLibrary('WinIo32.dll');' • $ make • The make step didn't work. It showed me a makefile error, so I tried to play with it without any luck. Since you're using a 32-bit version of Windows you can use the Cygwin port of pciutils.

The files in the win32 subdirectory are actually for the MinGW port, and that's why you get the link errors. The first thing you should do unpack the source files to a new directory so you can start from fresh. Your changes and modifications aren't necessary to compile it using Cygwin. Be sure not to copy any of the files in the win32 directory this time, they're not needed. Also don't copy the winio32 files, you don't need them either. Don't make any changes to any of the files.

The next thing to do is to install the ioperm package using Cygwin's setup-x86.exe. Type ioperm in the search box to quickly find it amongst all the other packages.

Once it's been installed run ioperm -i from the Cygwin prompt to install the driver that allows applications to do direct I/O. Next change directory to where you unpacked the fresh copy of pciutils and run the following command from the Cygwin shell: make HOST=i386-pc-cygwin That should be all you need to do to create the library and utilities.

Well whamma gave a very good answer [but] there's one thing he was wrong about, which is region sizes. Region sizes are pretty easy to find, here i will show two ways, the first by deciphering it from the address of the bar, the second through Windows user interface. Let's assume that E2000000 is the address of the Base Register. If we convert that to binary we get: 00 Now there are 32 bits here in total, you can count them if you must. Now if you are not familiar with how the bits in a BAR are layed out, look here ->, specifically 'Base Address Registers' and more specifically the image that reads 'Memory Space BAR Layout'.

Now lets start reading the bits from the right end to the left end and use the image in the link i pointed to you above as a guide. So the first bit(Bit 0) starting from the right is 0, indicating that this is a memory address BAR. Bits(1-2) are 0, indicating that it's a 32-bit(note this is not the size) memory BAR. Bit 3 is 0, indicating that it's not Prefetchable memory. Now we eliminated the useless bits lets continue to the good part, bits 4- 31. If you look at bit's 4 -31 you will notice that the first bit that is a '1' is Bit 24. Here is where some math come into play.

First we have to find the binary weighted value of Bit 24, which is 16777216, which is also 16777216 bytes, which is 16 MB, which tells us the size of the memory allocated by the BAR is 16 MB. If your wondering how i got the binary weighted value of bit 24, it goes like this: 2(binary is base 2) multiplied by itself 24(Bit 24) times, or 2 to the power of 24, or 2^24. The other way is using Device Manager: Start->'Device Manager'->Display Adapters->Right Click your video card->Properties->Resources. Each resource type marked 'Memory Range' should be a memory BAR and as you can see it says [start address] to [end address]. For example lets say it read [000000 - 00000000E2FFFFFF], to get the size you would take [start address] from [end address]: 00000000E2FFFFFF - 000000 = FFFFFF, FFFFFF in decimal = 16777215 = 16777215 bytes = 16MB.

How this works is pretty complicated. PCI devices use Base Address Registers to let the BIOS and Operating System decide where to locate their memory regions. Each PCI device is allowed to specify several memory or IO regions it wants, and lets the BIOS/OS decide where to put it.

Complicating matters, there's only one register that is used both to specify the size AND the address. How does this work? When the card is first powered up, it's 32-bit address register will have something like 0xFFFF0000 in it. Any binary 1 means 'the OS can change this', any binary 0 means 'must stay zero'. So this is telling the OS that any of the top 16 bits can be set to whatever the OS wants, but the bottom 16 bits have to stay zero.

Which also means that this memory region takes up 16 bits of address space, or 64k. Because of this, memory regions have to be aligned to their size.

If a card wants 64K of address space, the OS can only put it on memory addresses that are a multiple of 64K. When the OS has decided where it wants to locate this card's 64K memory space, it writes it back into this register, overwriting the initial 0xFFFF0000 that was in there. In other words, the card tells the OS what size/alignment it needs for the memory, then the OS overwrites that same register/variable with the address for the memory.

Once it's done this, you can't get the size back out of the register without resetting the address. This means there's no portable way of asking a card how big its region is, all you can ask it is WHERE the region is. So why does this work in Linux?

Because it's asking the kernel for this information. The kernel has an API to provide this stuff, the same way that lspci works. I am not a Windows expert, but I'm unaware of any way for an application to ask the Windows kernel this information. There may be an API to do this somehow, or you may need to write something that runs on the kernel side to pass this information back to you.

If you look in the libpci source, for windows it calls the 'generic' version of pci_fill_info(), which returns: return flags & ~PCI_FILL_SIZES; which basically means 'I'm returning everything you asked for, but the sizes.' BUT, this may not matter anyway. If all you're doing is wanting to read/write to the I2C registers, they're usually (always?) in the first 4K of the control/configuration region.

You can probably just map 4K (one page) and ignore the fact that there might be more. Also be warned that you may need to take additional steps to stop the real driver for this card from reading/writing while you are. If you're bit-banging the I2C bus manually, and the driver tries to at the same time, it's likely to cause a mess on the bus. There also may be an existing way to ask the radeon driver to do I2C requests for you, which might avoid all of this. (also note I'm simplifying and glossing over a lot of details with how the BARs work, including 64 bit addresses, I/O space, etc, read PCI documentation if you want to learn more). I believe you can rely on the fact that if the registers you are looking for are in BAR2, they'll always be there.

Flipping through several PCI drivers that I do have the source to, they are all assuming that the first memory BAR means one thing, the second means another, etc. I don't see any examples of using the size to determine which the correct BAR is. So I think you're safe here. If it's crashing if you try mapping sizes less than a certain amount then you're correct that you need to map more. Map at least enough to reach the furthest register you need to touch. – Nov 24 '12 at 0:16.
