2005-07-10drm: add test for AGP devices and driver override for it.Dave Airlie
Added device_is_agp callback to drm_driver. This function is called by the platform-specific drm_device_is_agp function. Added implementation of this function the the Linux-specific portion of the MGA driver to detect PCI G450 cards. Added code to the Linux-specific portion of the generic DRM layer to not initialize AGP infrastructure if the card is not AGP (this matches what already existed in BSD). Fix up i810/i830 and i915 drivers to always return AGP as they don't always report the capability. Fix the MGA to not report AGP for a card that has an AGP chip behind a PCI bridge.

2005-07-07[PATCH] mostly_read data sectionChristoph Lameter
Add a new section called ".data.read_mostly" for data items that are read frequently and rarely written to like cpumaps etc. If these maps are placed in the .data section then these frequenly read items may end up in cachelines with data is is frequently updated. In that case all processors in an SMP system must needlessly reload the cachelines again and again containing elements of those frequently used variables. The ability to share these cachelines will allow each cpu in an SMP system to keep local copies of those shared cachelines thereby optimizing performance.

2005-07-07[PATCH] tty output lossage fixRoman Zippel
The patch fixes a few corner cases around tty line editing with very long input lines: - n_tty_receive_char(): don't simply drop eol characters, otherwise canon_data isn't increased and the reader isn't woken up. - n_tty_receive_room(): If there is no newline pending and the edit buffer is full, allow only a single character to be written (until eol is found and the line is flushed), so characters from the next line aren't dropped. - write_chan(): if an incomplete line was written, continue writing until write() returns 0, otherwise it might not write the eol character to flush the line and the writer goes to sleep without ever being woken up. BTW the core problem is that part of this should be handled in the receive_buf path, but for this it has to return the number of written characters, as the amount of written characters may not be the same as the amount of characters going into the write buffer, so the receive_room() usage in pty_write() is not really reliable. Alan said: The problem looks valid. The behaviour of 'traditional unix' appears to be the following If you exceed the line limit then beep and drop the character Always allow EOL to complete a canonical line input Always do signal/control processing if enabled Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-07-07[PATCH] hvc_console: Register ops when setting up hvc_consoleMilton Miller

2005-07-07[PATCH] hvc_console: Separate hvc_console and vio codeMilton Miller
Separate the console setup routines of the hvc_console and the vio layer. Remove the call to find_init_vty from hvc_console.c. Fail the setup routine if the console doesn't exist, but register the console again when the specified channel is instantiated. This scheme maintains the print buffer semantics while eliminating callout and call back for the console code.

2005-07-07[PATCH] hvc_console: Rearrange codeMilton Miller
Milton Miller has done a lot of work to clean up our hvc_console code. One of the important things the following patch series does is separate the VIO layer from the hvc_console code. With the VIO specific code removed any ppc64 platform, or even any architecture, can use hvc_console as a generic polling console. You simply have to supply a get_chars and put_chars method and hvc_console does the rest of the work. You can even use it for an interrupt driven console. This patch: Rearrange the code in drivers/char/hvc_console.c to make future patches smaller. No actual code changes, just ordering of the functions in the file.

2005-07-01[PATCH] PCI: clean up dynamic pci id logicGreg Kroah-Hartman
The dynamic pci id logic has been bothering me for a while, and now that I started to look into how to move some of this to the driver core, I thought it was time to clean it all up. It ends up making the code smaller, and easier to follow, and fixes a few bugs at the same time (dynamic ids were not being matched everywhere, and so could be missed on some call paths for new devices, semaphore not needed to be grabbed when adding a new id and calling the driver core, etc.) I also renamed the function pci_match_device() to pci_match_id() as that's what it really does.
