2005-08-05drm: switch drm_handle_t to unsigned intDave Airlie
This converts the drm_handle_t to unsigned int. This is currently safe to do as we don't pass these across the kernel/user boundary, but userspace does use these, but no-one builds userspace against the kernel headers at present so it is okay to switch over the kernel copy of drm.h at this point. (The CVS tree will switch over soon in sync with some Mesa changes) From: Egbert Eich <eich@suse.de> Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-08-05drm: updated DRM map patch for 32/64 bit systemsDave Airlie
I basically combined Paul's patches with additions that I had made for PCI scatter gather. I also tried more carefully to avoid problems with the same token assigned multiple times while trying to use the base address in the token if possible to gain as much backward compatibility as possible for broken DRI clients.

2005-08-03[PATCH] ARM: 2833/2: Remove support for WDIOF_MAGICCLOSE from sa1100-wdtIan Campbell
Patch from Ian Campbell On PXA255 there is no way to disable the watchdog. Turning off OIER[E3] as suggested in the existing comment does not work. I posted a note to the ARM mailing list a little while ago asking for opinions from people using SA1100. There was one reponse from Nico who believes that the SA1100 is the same as the PXA255 in this respect. You also asked me to involve the watchdog maintainer which I tried to do but didn't hear anything back. There are only a couple of other drivers which can't stop the watchdog and there seems to be no consistancy regarding printing an error etc. I decided to print something since that matches the case for all the other drivers when NOWAYOUT is turned on. Also, I changed the device .name to "watchdog" like most of the other watchdogs. udev uses it as the device name (by default) and spaces etc. get in the way. Superceded 2833/1 because 2.6.13-rc4 caused rejects. Signed-off-by: Ian Campbell <icampbell@arcom.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-07-29[PATCH] agp: restore APBASE after setting APSIZEMatthew Garrett
When leaving S3 state, the AGP bridge may not have all PCI configuration registers set in the same way as they were at boot. This should be fixed by pci_restore_state - however, the APBASE register cannot be set to conflict with the APSIZE register. If APSIZE is larger than it was before suspend, pci_restore_state will not restore APBASE correctly. The attached patch adds an extra item to the agp_bridge_data structure and uses it to store the value of APBASE. On resume, this is then written after APSIZE has been set. This patch only touches the path used for Intel chipsets without integrated graphics, and may need to be extended to work with the others. Without this patch, I get the symptoms described in bug 4921 - APBASE ends up overlapping various PCI devices, and as a result they fail to work after resume.

2005-07-27[PATCH] clean up inline static vs static inlineJesper Juhl
`gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

2005-07-10Add support for PCI MGA cards to MGA DRM.Dave Airlie
This patch adds serveral new ioctls and a new query to get_param query to support PCI MGA cards. Two ioctls were added to implement interrupt based waiting. With this change, the client-side driver no longer needs to map the primary DMA region or the MMIO region. Previously, end-of-frame waiting was done by busy waiting in the client-side driver until one of the MMIO registers (the current DMA pointer) matched a pointer to the end of primary DMA space. By using interrupts, the busy waiting and the extra mappings are removed. A third ioctl was added to bootstrap DMA. This ioctl, which is used by the X-server, moves a *LOT* of code from the X-server into the kernel. This allows the kernel to do whatever needs to be done to setup DMA buffers. The entire process and the locations of the buffers are hidden from user-mode. Additionally, a get_param query was added to differentiate between G4x0 cards and G550 cards. A gap was left in the numbering sequence so that, if needed, G450 cards could be distinguished from G400 cards. According to Ville Syrjälä, the G4x0 cards and the G550 cards handle anisotropic filtering differently. This seems the most compatible way to let the client-side driver know which card it's own. Doing this very small change now eliminates the need to bump the DRM minor version twice. http://marc.theaimsgroup.com/?l=dri-devel&m=106625815319773&w=2 (airlied - this may not work at this point, I think the follow on buffer cleanup patches will be needed) From: Ian Romanick <idr@us.ibm.com> Signed-off-by: Dave Airlie <airlied@linux.ie>

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).

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>
