* md: never advance 'events' counter by more than 1.NeilBrown2009-08-131-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | When assembling arrays, md allows two devices to have different event counts as long as the difference is only '1'. This is to cope with a system failure between updating the metadata on two difference devices. However there are currently times when we update the event count by 2. This was done to keep the event count even when the array is clean and odd when it is dirty, which allows us to avoid writing common update to spare devices and so allow those spares to go to sleep. This is bad for the above reason. So change it to never increase by two. This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, but that is only a small cost. The spares will get a few more updates but that will still be spared (;-) most updates and can still go to sleep. Prior to this patch there was a small chance that after a crash an array would fail to assemble due to the overly large event count mismatch. Signed-off-by: NeilBrown <neilb@suse.de>
* Remove deadlock potential in md_openNeilBrown2009-08-102-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent commit: commit 449aad3e25358812c43afc60918c5ad3819488e7 introduced the possibility of an A-B/B-A deadlock between bd_mutex and reconfig_mutex. __blkdev_get holds bd_mutex while calling md_open which takes reconfig_mutex, do_md_run is always called with reconfig_mutex held, and it now takes bd_mutex in the call the revalidate_disk. This potential deadlock was not caught by lockdep due to the use of mutex_lock_interruptible_nexted which was introduced by commit d63a5a74dee87883fda6b7d170244acaac5b05e8 do avoid a warning of an impossible deadlock. It is quite possible to split reconfig_mutex in to two locks. One protects the array data structures while it is being reconfigured, the other ensures that an array is never even partially open while it is being deactivated. In particular, the second lock prevents an open from completing between the time when do_md_stop checks if there are any active opens, and the time when the array is either set read-only, or when ->pers is set to NULL. So we can be certain that no IO is in flight as the array is being destroyed. So create a new lock, open_mutex, just to ensure exclusion between 'open' and 'stop'. This avoids the deadlock and also avoids the lockdep warning mentioned in commit d63a5a74d Reported-by: "Mike Snitzer" <snitzer@gmail.com> Reported-by: "H.

| * USB: EHCI: fix two new bugs related to Clear-TT-BufferAlan Stern2009-08-072-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1273) fixes two(!) bugs introduced by the new Clear-TT-Buffer implementation in ehci-hcd. It is now possible for an idle QH to have some URBs on its queue -- this will happen if a Clear-TT-Buffer is pending for the QH's endpoint. Consequently we should not issue a warning when someone tries to unlink an URB from an idle QH; instead we should process the request immediately. The refcounts for QHs could get messed up, because submit_async() would increment the refcount when calling qh_link_async() and qh_link_async() would then refuse to link the QH into the schedule if a Clear-TT-Buffer was pending. Instead we should increment the refcount only when the QH actually is added to the schedule. The current code tries to be clever by leaving the refcount alone if an unlink is immediately followed by a relink; the patch changes this to an unconditional decrement and increment (although they occur in the opposite order).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had one report of flicker due to FIFO underruns on 845G. Scott was kind enough to test a few patches and report success with this one. Looks like 845G measures FIFO size slightly differently than other chips, and we were also clobbering the FIFO burst length. Fixing both of those issues gives him a healthy machine again. Note that we still only adjust plane A's watermark in the 830/845 case. If someone is willing to test we could support a bigger variety of dual-head 830/845 configurations with a bit more code.

For example: the size is 46. But it seems that the size of lvds_fp_timing varies on the differnt platform. In such case we will get the incorrect DVO timing entry because of the incorrect DVO offset in LVDS panel data entry. This also removes a hack on new IGDNG to get proper DVO timing. Calculate the DVO timing offset in LVDS data entry to get the DVO timing a. get the DVO timing offset in the LVDS fp data entry by using the pointer definition in LVDS data ptr b. get the LVDS data entry c. get the DVO timing by adding the DVO timing offset to data entry https://bugs.freedesktop.org/show_bug.cgi?id=22787 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Zhenyu Wang <zhenyuw@linux.intel.com> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I discovered several bugs in the FIFO code that was recently applied. Some of them fell into the "how did this ever work" category, since in some cases we were using the wrong FIFO size values, and the calculations ended up being way off. This patch fixes all the bugs I found, and works well on my GM45, 915GM and 855GM test machines; but as usual with these sorts of patches broader testing is definitely requested (in particular this patch affects 830, 845 and 865 for which I don't have test hardware). Overall, the patch clarifies the watermark calculation function by adding some comments and debug info, and making the variable names a bit clearer. The "get FIFO size" portion of the code has also been corrected, so we should be able to properly detect the FIFO allocations for each pipe, for use in the watermark calculation.

| * drm/i915: Allow frame buffers up to 4096x4096 on 915/945 class hardwareKeith Packard2009-07-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | The 915 and 945 scanout engines can handle frame buffers up to 4096 pixels wide. Pre-9xx hardware has an 8192 byte stride limit, and so we leave the existing 2048 max in place. I'm not sure why we limit the height to the same value; there's no intrinsic hardware limit in the scanout engine.

| * drm/i915: refactor error detection & collectionJesse Barnes2009-07-133-74/+161
| | | | | | | | | | | | | | | | | | | | | | | | This patch refactors the existing error detection and collection code, placing most of it in i915_handle_error(). Additionally, we introduce a work queue for scheduling post-crash tasks such as generating a uevent. Using the uevent facility, userspace should be able to capture a post-mortem dump for diagnostics.

So it is possible to get a random value. 2. One line added by commit 2c2e2c38("IOMMU Identity Mapping Support") change the code path, let it bypass domain_update_iommu_cap(), as well as missing the increment of domain iommu reference count. The latter is also likely to cause a leak of domains on repeated VMM assignment and deassignment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In domain_sg_mapping(), use aligned_nrpages() instead of hand-coded rounding code for calculating the size of each sg elem. This means that on IA64 we correctly round up to the MM page size, not just to the VT-d page size. Also remove the incorrect mm_to_dma_pfn() when intel_map_sg() calls domain_sg_mapping() -- the 'size' variable is in VT-d pages already.
