Currently registering CvP managers works only for first probed CvP device, for all other devices it is refused due to duplicated chkcfg sysfs entry: fpga_manager fpga3: Altera CvP FPGA Manager @0000:0c:00.0 registered sysfs: cannot create duplicate filename '/bus/pci/drivers/altera-cvp/chkcfg' CPU: 0 PID: 3808 Comm: bash Tainted: G O 4.19.0-custom+ #5 Call Trace: dump_stack+0x46/0x5b sysfs_warn_dup+0x53/0x60 sysfs_add_file_mode_ns+0x16d/0x180 sysfs_create_file_ns+0x51/0x60 altera_cvp_probe+0x16f/0x2a0 [altera_cvp] local_pci_probe+0x3f/0xa0 ? pci_match_device+0xb1/0xf0 pci_device_probe+0x116/0x170 really_probe+0x21b/0x2c0 driver_probe_device+0x4b/0xe0 bind_store+0xcb/0x130 kernfs_fop_write+0xfd/0x180 __vfs_write+0x21/0x150 ? selinux_file_permission+0xdc/0x130 vfs_write+0xa8/0x1a0 ? find_vma+0xd/0x60 ksys_write+0x3d/0x90 do_syscall_64+0x44/0xf0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 ... altera-cvp 0000:0c:00.0: Can't create sysfs chkcfg file fpga_manager fpga3: fpga_mgr_unregister Altera CvP FPGA Manager @0000:0c:00.0 Move chkcfg creation to module init as suggested by Alan.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
