| alim15x3: ULI M-1573 south Bridge support | KAI.HSU | Sun, 09 Apr 2006 21:35:01 -0700 | 1 files changed, 2 insertions(+) | 670 Bytes |
| From http://bugzilla.kernel.org/show_bug.cgi?id=6358 The alim15x3.c hasn't been update for 3 years. Recently when we used this "ULI M1573" south bridge chip we couldn't mount a CDROM(VCD) smoothly and had to wait for a long time. After I checked the "ULI M1573" south bridge datasheet, I found the reason. The "ULI M1573" version is "0xC7", not "0xC4" anymore. So I modified the source and it was successed.

| block: delay all uevents until partition table is scanned | Kay Sievers | Sun, 26 Mar 2006 15:00:24 -0800 | 2 files changed, 32 insertions(+), 9 deletions(-) | 3474 Bytes |
| Here we delay the annoucement of all block device events until the disk's partition table is scanned and all partition devices are already created and sysfs is populated. We have a bunch of old bugs for removable storage handling where we probe successfully for a filesystem on the raw disk, but at the same time the kernel recognizes a partition table and creates partition devices. Currently there is no sane way to tell if partitions will show up or not at the time the disk device is announced to userspace. With the delayed events we can simply skip any probe for a filesystem on the raw disk when we find already present partitions.

| radeonfb: powerdrain issue on IBM thinkpads and suspend-to-D2 | Giorgio Lando | Sun, 16 Apr 2006 17:28:27 -0700 | 2 files changed, 133 insertions(+), 2 deletions(-) | 517 Bytes |
| Many IBM Thinkpad T4* models and some R* and X* with radeon video cards, when suspended to RAM, draw too much power, reducing drastically the battery lifetime. The solution is to enable suspend-to-D2 on non-PPC-machines. Since this is in general not well documented, suspend-to-D2 is enabled only on machines where it is known to work. These machines are identified through their DMI strings and listed in a white-list into the patch itself. This behaviour can be overriden with module options: through these options suspend-to-D2 can be: - enabled also on non-whitelisted machines (since the white-list is partial and can be enlarged in the time); - disabled on whitelisted machines, in case of negative side-effects. The module options can be passed at boot time including the following corresponding parameter in the kernel command line: - video=radeonfb:force_sleep=1 - video=radeonfb:nosleep=1 Signed-off-by: Antti Andreimann <Antti.Andreimann@mail.ee> Signed-off-by: Thomas De Grenier De Latour <degrenier@easyconnect.fr> Signed-off-by: Giorgio Lando <patroclo7@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> |

| sched: prevent high load weight tasks suppressing balancing | Peter Williams | Tue, 28 Mar 2006 23:12:09 -0800 | 1 files changed, 27 insertions(+), 8 deletions(-) | 3289 Bytes |
| Problem: On systems with more than 2 CPUs it is possible for a single task with a high smpnice load weight to suppress load balancing on other CPUs (to the one that it's running on) if it is the only runnable task on its CPU. E.g. consider a 4-way system (simple SMP system with no HT and cores) scenario where a high priority task (nice-20) is running on P0 and two normal priority tasks running on P1. load balance with smp nice code will never be able to detect an imbalance and hence will never move one of the normal priority tasks on P1 to idle cpus P2 or P3 as P0 will always be identified as the busiest CPU but it has no tasks that can be moved. Solution: Make sure that only CPUs with tasks that can be moved get selected as the busiest queue. This involves ensuring that find_busiest_group() only considers groups that have at least one CPU with more than one task running as candidates for the busiest group and that find_busiest_queue() only considers CPUs that have more than one task running as candidates for the busiest run queue. One effect of this is that load balancing will be abandoned earlier in the sequence (i.e. before the double run queue locks are taken prior to calling move_tasks() rather than in move_tasks() itself) when there are no tasks that can be moved than would be the case without this patch. However, it is undesirable for HT/MC packages to have more than one of their CPUs busy if there are other packages that have all of their CPUs idle. This involves moving the only running task (i.e. the one actually on the CPU) off on to another CPU and is achieved by using active_load_balance() and relying on the fact that (when it starts) the queue's migration thread will preempt the sole running task and (therefore) make it movable. The migration thread then moves it to an idle package. Unfortunately, the mechanism for setting the run queues active_balance flag is buried deep inside load_balance() and relies heavily on find_busiest_group() and find_busiest_queue() reporting success even if the busiest queue has only one task running. To support this requirement the solution has been modified so that queues with only one task will be found (if there are none available with more than 1 task) if the value of idle passed to find_busiest_group() and find_busiest_queue() is not NEWLY_IDLE which will never be true when they are called from load_balance(). This sub optimal modification should be removed when a proper implementation of the HT/MC special balancing requirements is available. PS: This doesn't take into account tasks that can't be moved because they are pinned to a particular CPU. At this stage, I don't think that it's worth the effort to make the changes that would enable this.

| swsusp: use less memory during resume | "Rafael J. Wysocki" | Wed, 19 Apr 2006 23:57:46 -0700 | 2 files changed, 85 insertions(+), 58 deletions(-) | 1142 Bytes |
| Make swsusp allocate only as much memory as needed to store the image data and metadata during resume. Without this patch swsusp additionally allocates many page frames that will conflict with the "original" locations of the image data and are considered as "unsafe", treating them as "eaten" pages (ie. allocated but unusable). The patch makes swsusp allocate as many pages as it'll need to store the data read from the image in one shot, creating a list of allocated "safe" pages, and use the observation that all pages allocated by it are marked with the PG_nosave and PG_nosave_free flags set. Namely, when it's about to load an image page, swsusp can check whether the page frame corresponding to the "original" location of this page has been allocated (ie. if the page frame has the PG_nosave and PG_nosave_free flags set) and if so, it can load the page directly into this page frame. Otherwise it uses an allocated "safe" page from the list to store the data that will be copied to their "original" location later on. This allows us to save many page copyings and page allocations during resume and in the future it may allow us to load images greater than 50% of the normal zone. Signed-off-by: Rafael J.

| zlib_inflate: Upgrade library code to a recent version | Richard Purdie | Fri, 7 Apr 2006 15:08:08 -0700 | 16 files changed, 1884 insertions(+), 2013 deletions(-) | 4474 Bytes |
| Upgrade the zlib_inflate implementation in the kernel from a patched version 1.1.3/4 to a patched 1.2.3. The code in the kernel is about seven years old and I noticed that the external zlib library's inflate performance was significantly faster (~50%) than the code in the kernel on ARM (and faster again on x86_32). For comparison the newer deflate code is 20% slower on ARM and 50% slower on x86_32 but gives an approx 1% compression ratio improvement. I don't consider this to be an improvement for kernel use so have no plans to change the zlib_deflate code. Various changes have been made to the zlib code in the kernel, the most significant being the extra functions/flush option used by ppp_deflate. This update reimplements the features PPP needs to ensure it continues to work. This code has been tested on ARM under both JFFS2 (with zlib compression enabled) and ppp_deflate and on x86_32. JFFS2 sees an approx. 10% real world file read speed improvement. This patch also removes ZLIB_VERSION as it no longer has a correct value. We don't need version checks anyway as the kernel's module handling will take care of that for us. This removal is also more in keeping with the zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've added something to the zlib.h header to note its a modified version.
