https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290793 --- Comment #2 from David BOYER <jcduss13@gmail.com> --- The bad behavior was introduced by the commit ff31767e530ab. The bar appears as not (yet?) valid I tried to find a function or a boolean such as "is_vf" to modify if condition, but I failed. The only working patch I could come up with is the following: diff --git a/sys/compat/linuxkpi/common/src/linux_pci.c b/sys/compat/linuxkpi/common/src/linux_pci.c index 8507a59a8df3..04ff817666a3 100644 --- a/sys/compat/linuxkpi/common/src/linux_pci.c +++ b/sys/compat/linuxkpi/common/src/linux_pci.c @@ -1223,12 +1223,6 @@ lkpi_pci_request_region(struct pci_dev *pdev, int bar, const char *res_name, if (!lkpi_pci_bar_id_valid(bar)) return (-EINVAL); - /* - * If the bar is not valid, return success without adding the BAR; - * otherwise linuxkpi_pcim_request_all_regions() will error. - */ - if (pci_resource_len(pdev, bar) == 0) - return (0); /* Likewise if it is neither IO nor MEM, nothing to do for us. */ type = pci_resource_type(pdev, bar); if (type < 0) -- You are receiving this mail because: You are the assignee for the bug.
