2007-05-08IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier
Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.

2007-05-08IB: Put rlimit accounting struct in struct ib_umemRoland Dreier
When memory pinned with ib_umem_get() is released, ib_umem_release() needs to subtract the amount of memory being unpinned from mm->locked_vm. However, ib_umem_release() may be called with mm->mmap_sem already held for writing if the memory is being released as part of an munmap() call, so it is sometimes necessary to defer this accounting into a workqueue. However, the work struct used to defer this accounting is dynamically allocated before it is queued, so there is the possibility of failing that allocation. If the allocation fails, then ib_umem_release has no choice except to bail out and leave the process with a permanently elevated locked_vm. Fix this by allocating the structure to defer accounting as part of the original struct ib_umem, so there's no possibility of failing a later allocation if creating the struct ib_umem and pinning memory succeeds.

2007-05-08IB/uverbs: Export ib_umem_get()/ib_umem_release() to modulesRoland Dreier
Export ib_umem_get()/ib_umem_release() and put low-level drivers in control of when to call ib_umem_get() to pin and DMA map userspace, rather than always calling it in ib_uverbs_reg_mr() before calling the low-level driver's reg_user_mr method. Also move these functions to be in the ib_core module instead of ib_uverbs, so that driver modules using them do not depend on ib_uverbs. This has a number of advantages: - It is better design from the standpoint of making generic code a library that can be used or overridden by device-specific code as the details of specific devices dictate. - Drivers that do not need to pin userspace memory regions do not need to take the performance hit of calling ib_mem_get(). For example, although I have not tried to implement it in this patch, the ipath driver should be able to avoid pinning memory and just use copy_{to,from}_user() to access userspace memory regions. - Buffers that need special mapping treatment can be identified by the low-level driver. For example, it may be possible to solve some Altix-specific memory ordering issues with mthca CQs in userspace by mapping CQ buffers with extra flags. - Drivers that need to pin and DMA map userspace memory for things other than memory regions can use ib_umem_get() directly, instead of hacks using extra parameters to their reg_phys_mr method. For example, the mlx4 driver that is pending being merged needs to pin and DMA map QP and CQ buffers, but it does not need to create a memory key for these buffers. So the cleanest solution is for mlx4 to call ib_umem_get() in the create_qp and create_cq methods. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-05-08vgacon: disallow console operations when in KD_GRAPHICS modeAntonino A. Daplas
Reported by James Pearson as: boot to run level 3 if not root, then make sure /dev/console is writeable login and type: setterm -blank 0 start X type into an xterm: while true; do echo "" > /dev/console; usleep 100000; done while the above loop is running switch to the text console and back again (Ctrl-Alt-F1 then Ctrl-Alt-F7) ... and the screen will be shifting (and wrapping) to the left. This problem stems from continuously writing text to the system console (which is in KD_TEXT mode) while the foreground console is in KD_GRAPHICS mode. Somewhere along the way, console printing got confused and omitted the KD_GRAPHICS/KD_TEXT test. Thus, vgacon attempted to scroll the screen of X, which causes X to shift. Fix by disallowing vgacon to touch the hardware when the vc is in KD_GRAPHICS mode. A definitive fix entails a full audit of the console code.

If the driver's capability cannot handle fbcon's requirement, then fb_set_var() will fail. For example, if a particular driver supports 2 modes where: mode1 = can only display 8x16 bitmaps mode2 = can display any bitmap then if current mode = mode2 and current font = 12x22 fbset <mode1> /* mode1 cannot handle 12x22 */ fbset will fail Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-08fbdev: save the activate field before calling fb_check_var()Antonino A. Daplas
Some drivers may reset the var->activate field on fb_check_var(). This can lead to undefined behavior. For example, doing fbset -a <option> with vga16fb will only modify the active console instead of modifying all.

2007-05-08fbcon: check if the character count can be handledAntonino A. Daplas
Fontmaps can be 256 or 512 in length. The only driver that can do tileblitting can only handle 256 characters. Check for this when setting the font.

2007-05-08fbdev: add tile operation to get the maximum length of the mapAntonino A. Daplas
Add a tile method, fb_get_tilemax(), that returns the maximum length of the tile map (or font map). This is needed by s3fb which can only handle 256 characters.

2007-05-08s3fb: limit 8x16 rectangles when tileblitting is enabledAntonino A. Daplas
If tileblitting is enabled (text mode), the hardware can only accept 8x16 bitmaps. Advertise this to the upper layer. And to ensure that an appropriate font is always available, select an 8x16 font in Kconfig.
