2011-11-28delete_io_handle: fix deletion of last handleDaniel Drake1-3/+8
When num_ios goes from 1 to 0, a realloc(ios, 0); call is made. This is equivalent to free(ios) and NULL is returned. However, the previous logic in the code incorrectly discards this NULL return value. When we next call new_io_handle(), realloc(ios, X) is called with "ios" pointing to freed memory. This causes glibc to abort. Correct this logic to detect the 1-to-0 case and handle it correctly. Other cases are unchanged; there is still value in checking the return value from realloc() as it also returns NULL on error.

2011-03-30Solaris support for multiple PCI segments (domains)John Martin2-63/+89
1. Removed hardcoded maximum size of 256 PCI devices, which is too small for large systems. The number of devices is dynamically resized as needed. 2. pci_device_solx_devfs_probe() no longer walks the device tree from the very top ("/") but instead starts at the nexus which owns the bus. Performance optimization for systems with multiple bus nodes (including systems with just one segment/domain). 3. Added support for multiple domains/segments. Code tested on kernels with and without multiple segment support so it should be safe to integrate independent of the kernel version.

Bit 7 of the pci device header type is an indicator of multi-function devices, so needs to be masked when examining the bridge type.

2010-12-06Revert "Don't try to use bogus bridge data"Jesse Barnes1-4/+0
This reverts commit 2bda5b733bb12854760750c08138db95e77aea0c. It actually conflicts with 9ba94caf57e3a8c3e9c6f3f5f068f4a7a7b3ff9d which came earlier, but I didn't catch it probably because I did a blind rebase before pushing. When reading bridge bus info, we may need to read out the current bridge info if the PCI bridge private is uninitialized, so remove the check at the top that would always short circuit the case where the priv was still 0.

No function changes. Note that automake generates a wrapper script if libpciaccess is not installed at configuration time, which is the most common case. If it is installed at configuration time, you get an executable. The makefile build order ensures the lib is build before scanpci.

Add an include that makes the file common_vgaarb.c see the same struct pci_system as the file linux_sysfs.c. Without this fix, on a MTRR system, the vgaarb_fd member would overwrite the mtrr_fd member and cause the MTRR_IOC_ADD_ENTRY call to be issued to the incorrect device causing the infamous "Inappropriate ioctl for device (25)" error. This error would cause MTRR setup to fail on all systems relying on it and is severe enough to warrant a new release.
