* [PATCH] fbdev: Fix incorrect unaligned access in little-endian machinesAntonino A. Daplas2005-12-121-0/+12
| | | | | | | | | | | | | | The drawing function cfbfillrect does not work correctly when access is not unsigned-long aligned. It manifests as extra lines of pixels that are not complete drawn. Reversing the shift operator solves the problem, so I would presume that this bug would manifest only on little endian machines. The function cfbcopyarea may also have this bug. Aligned access should present no problems. Signed-off-by: Antonino Daplas <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fbdev: fix switch to KD_TEXT, enhanced versionKnut Petersen2005-12-121-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every framebuffer driver relies on the assumption that the set_par() function of the driver is called before drawing functions and other functions dependent on the hardware state are executed. Whenever you switch from X to a framebuffer console for the very first time, there is a chance that a broken X system has _not_ set the mode to KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and several other functions before a set_par() is executed. This is believed to be not a bug of linux but a bug of X/xdm. At least some X releases used by SuSE and Debian show this behaviour. There was a 2nd case, but that has been fixed by Antonino Daplas on 10-dec-2005. This patch allows drivers to set a flag to inform fbcon_switch() that they prefer a set_par() call on every console switch, working around the problems caused by the broken X releases. The flag will be used by the next release of cyblafb and might help other drivers that assume a hardware state different to the one used by X. As the default behaviour does not change, this patch should be acceptable to everybody. Signed-off-by: Knut Petersen <Knut_Petersen@t-online.de> Acked-by: "Antonino A.

This is needed by savagefb at least so it can cooperate with savage_dri and by cyblafb. State save/restoration can be full or partial.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a customer application which trips a bug. The problem arises when a driver attempts to call do_munmap on an area which is mapped, but because current->thread.task_size has been set to 0xC0000000, the call to do_munmap fails thinking it is an unmap beyond the user's address space. The comment in fs/binfmt_elf.c in load_elf_library() before the call to SET_PERSONALITY() indicates that task_size must not be changed for the running application until flush_thread, but is for ia64 executing ia32 binaries. This patch moves the setting of task_size from SET_PERSONALITY() to flush_thread() as indicated. The customer application no longer is able to trip the bug.

It introduces two new flags. IN_ONLYDIR -- only watch the inode if it is a directory. This is needed to avoid the race that can occur when we want to be sure that we are watching a directory. IN_DONT_FOLLOW -- don't follow a symlink. In combination with IN_ONLYDIR we can make sure that we don't watch the target of symlinks.

* | [PATCH] Add timestamp field to process eventsMatt Helsley2005-12-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a timestamp field to the events sent via the process event connector. The timestamp allows listeners to accurately account the duration(s) between a process' events and offers strong means with which to determine the order of events with respect to a given task while also avoiding the addition of per-task data. This alters the size and layout of the event structure and hence would break compatibility if process events connector as it stands in 2.6.15-rc2 were released as a mainline kernel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a new interface - rcu_barrier() which waits until all the RCUs queued until this call have been completed. Reiser4 needs this, because we do more than just freeing memory object in our RCU callback: we also remove it from the list hanging off super-block. This means, that before freeing reiser4-specific portion of super-block (during umount) we have to wait until all pending RCU callbacks are executed. The only change of reiser4 made to the original patch, is exporting of rcu_barrier(). Cc: Hans Reiser <reiser@namesys.com> Cc: Vladimir V.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On most powerpc CPUs, the dcache and icache are not coherent so between writing and executing a page, the caches must be flushed. Userspace programs assume pages given to them by the kernel are icache clean, so we must do this flush between the kernel clearing a page and it being mapped into userspace for execute. We were not doing this for hugepages, this patch corrects the situation. We use the same lazy mechanism as we use for normal pages, delaying the flush until userspace actually attempts to execute from the page in question. Tested on G5.

| | | | | | | | | | | | | | | | | | | | | | | | | | ARMv6K CPUs have SEV (send event) and WFE (wait for event) instructions which allow the CPU clock to be suspended until another CPU issues a SEV, rather than spinning on the lock wasting power. Make use of these instructions. Note that WFE does not wait if an event has been sent since the last WFE cleared the event status, so although it may look racy, the instruction implementation ensures that these are dealt with.
