From dankwiki
Reverse engineering of CUDA ioctls in the 3.0 SDK (195.36.15 driver, GTS 360M, amd64). CUDA primarily communicates with the NVIDIA closed-source driver via several hundred undocumented ioctl()s. My open source implementation is located at GitHub.
Maps
Ordered from highest to lowest locations in x86 memory. These are architecture-, and to a lesser degree driver- and kernel version-specific. Applications and libraries can of course create many more maps than these.
- vsyscalls. read-execute-private, very few pages, topmost area of memory, usually highest mapping
- VDSO. read-execute-private, one page, high in memory (SYSENTER/SYSEXIT)
- Userspace stack. read-write-private, many pages, high in memory
- Anonymous map, 3 read-write-private pages, high in memory.
- Possibly associated with nvidia driver's NV_STACK_SIZE stack. read-write-private, (3 * 4096 on amd64, 2 * 4096 on i686)
- Two sets of /dev/nvidiaX maps for each bound device. Sets are usually continguous, and contain:
- an anonymous page, read-write-private
- several mappings of the device, having variable number of pages, all read-write-shared
- Libraries. variable, middle of memory.
- Userspace heap. read-write-private, many pages, low in memory
- Application (data region). read-write-private, variable, low in memory
- Application (text region). read-execute-private, variable, usually lowest mapping
ioctls
An ioctl (on x86) is 32 bits. The following definition comes from linux/asm-generic/ioctl.h in a 2.6.34 kernel:
- Bit 31: Read?
- Bit 30: Write?
- Bits 29-16: Parameter size
- Bits 15-8: Type (module)
- Bits 7-0: Number (command)
Looking at the source of the 195.36.15 kernel driver's OS interface, we see that NVIDIA uses the standard ioctl-creation macros from ioctl.h, and can be expected to adhere to this format. The type code used (NV_IOCTL_MAGIC) is 'F' (0x46), which overlaps with the framebuffer ioctl range as registered in 2.6.34. We further see that only _IOWR() is used to declare ioctls, implying that the first two bits will always be '11'. Both of these deductions are borne out observing strace output of a CUDA process.
