2013-02-21drm/i915: Handle untiled planes when computing their offsetsChris Wilson
We trim the fb to fit the CRTC by computing the offset of that CRTC to its nearest tile_row origin. This allows us to use framebuffers that are larger than the CRTC limits without additional work. However, we failed to compute the offset for a linear framebuffer correctly as we treated its x-advance in whole tiles (instead of the linear increment expected), leaving the CRTC misaligned with its contents. Fixes regression from commit c2c75131244507c93f812862fdbd4f3a37139401 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Jul 5 12:17:30 2012 +0200 drm/i915: adjust framebuffer base address on gen4+ v2: Adjust relative x-coordinate after linear alignment (vsyrjala) v3: Repaint with pokadots (vsyrjala) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=61152 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: stable@vger.kernel.org Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-02-21IB/core: Add "type 2" memory windows supportShani Michaeli
This patch enhances the IB core support for Memory Windows (MWs). MWs allow an application to have better/flexible control over remote access to memory. Two types of MWs are supported, with the second type having two flavors: Type 1 - associated with PD only Type 2A - associated with QPN only Type 2B - associated with PD and QPN Applications can allocate a MW once, and then repeatedly bind the MW to different ranges in MRs that are associated to the same PD. Type 1 windows are bound through a verb, while type 2 windows are bound by posting a work request. The 32-bit memory key is composed of a 24-bit index and an 8-bit key. The key is changed with each bind, thus allowing more control over the peer's use of the memory key. The changes introduced are the following: * add memory window type enum and a corresponding parameter to ib_alloc_mw. * type 2 memory window bind work request support. * create a struct that contains the common part of the bind verb struct ibv_mw_bind and the bind work request into a single struct. * add the ib_inc_rkey helper function to advance the tag part of an rkey. Consumer interface details: * new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support for these features. Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B memory windows. It can set neither to indicate it doesn't support type 2 windows at all. * modify existing provides and consumers code to the new param of ib_alloc_mw and the ib_mw_bind_info structure Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Shani Michaeli <shanim@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

2013-02-21posix-timer: Don't call idr_find() with out-of-range IDTejun Heo
When idr_find() was fed a negative ID, it used to look up the ID ignoring the sign bit before recent ("idr: remove MAX_IDR_MASK and move left MAX_IDR_* into idr.c") patch. Now a negative ID triggers a WARN_ON_ONCE(). __lock_timer() feeds timer_id from userland directly to idr_find() without sanitizing it which can trigger the above malfunctions. Add a range check on @timer_id before invoking idr_find() in __lock_timer(). While timer_t is defined as int by all archs at the moment, Andrew worries that it may be defined as a larger type later on. Make the test cover larger integers too so that it at least is guaranteed to not return the wrong timer. Note that WARN_ON_ONCE() in idr_find() on id < 0 is transitional precaution while moving away from ignoring MSB. Once it's gone we can remove the guard as long as timer_t isn't larger than int.

This is due to the patch not having sufficient lines of context to distinguish the two places of application. The effect of this is relatively minor: inside the kernel, the keyring search routines may search multiple keyrings and then prioritise the errors if no keys or negative keys are found in any of them. With the extra deletion, the presence of a negative key in the thread keyring (causing ENOKEY) is incorrectly overridden by an error searching the process keyring. So revert the second application of the patch.

2013-02-21edac: lock module owner to avoid error report conflictsMauro Carvalho Chehab
APEI GHES and i7core_edac/sb_edac currently can be loaded at the same time, but those are Highlander modules: "There can be only one". There are two reasons for that: 1) Each driver assumes that it is the only one registering at the EDAC core, as it is driver's responsibility to number the memory controllers, and all of them start from 0; 2) If BIOS is handling the memory errors, the OS can't also be doing it, as one will mangle with the other. So, we need to add an module owner's lock at the EDAC core, in order to avoid having two different modules handling memory errors at the same time. The best way for doing this lock seems to use the driver's name, as this is unique, and won't require changes on every driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Create a debugfs direcotry i5100_edac/mcX for each memory controller and add nodes to control how fault injection is preformed. After configuring an injection using inject_channel, inject_deviceptr1, inject_deviceptr2, inject_eccmask1, inject_eccmask2 and inject_hlinesel trigger the injection by writing anything to inject_enable. Example of a CE injection: echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel echo 61440 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1 echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable Example of UE injection: echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_channel echo 2 > /sys/kernel/debug/i5100_edac/mc0/inject_hlinesel echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask1 echo 65535 > /sys/kernel/debug/i5100_edac/mc0/inject_eccmask2 echo 17 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr1 echo 0 > /sys/kernel/debug/i5100_edac/mc0/inject_deviceptr2 echo 1 > /sys/kernel/debug/i5100_edac/mc0/inject_enable Sometimes it is needed to enable the injection more then once (echo to the inject_enable node) for the injection to happen, I am not sure why.

2013-02-21i3200_edac: Fix the logic that detects filled memoriesMauro Carvalho Chehab
After running a series of tests on an HP DL320, filled with different memory sizes, it was noticed that, when filled with just one DIMM on such hardware, the driver wrongly detects twice the memory, and thinks that both channels 0 and 1 are filled. It seems to be partially caused by the BIOS and partially by the driver. The i3200_edac current logic would be working fine if the BIOS were disabling the unused second channel when just one DIMM is connected, in order to do power-saving, as recommended on this chipset's datasheet. However, the BIOS on this particular machine doesn't do it: [ 16.741421] EDAC DEBUG: how_many_channels: In dual channel mode [ 16.741424] EDAC DEBUG: how_many_channels: 2 DIMMS per channel enabled So, the driver were assuming that 2 channels are enabled (well, they are, but the second is unused). Combined with that, I found two issues at the logic that creates the EDAC data, that were failing when the two channels are not equally filled (AFAICT, that happens only when just 1 DIMM is plugged). The first one is that a 0 at DRB means that nothing is filled. The driver's logic, however, do some calculation with that. The second one is that the logic that fills the DIMM data currently assumes that both channels are equally filled. I tested the system already with the current configuration and my patch and it is now working fine. So, for a 2R single DIMM 2Gb memory at dimm slot 01 (channel 0), it is now displaying: [ 16.741406] EDAC DEBUG: i3200_get_drbs: drb[0][0] = 16, drb[1][0] = 0 [ 16.741410] EDAC DEBUG: i3200_get_drbs: drb[0][1] = 32, drb[1][1] = 0 [ 16.741413] EDAC DEBUG: i3200_get_drbs: drb[0][2] = 32, drb[1][2] = 0 [ 16.741416] EDAC DEBUG: i3200_get_drbs: drb[0][3] = 32, drb[1][3] = 0 ...

When udelay() is implemented using an architected timer, it is wrong to scale loops_per_jiffy when changing the CPU clock frequency since the timer clock remains constant. The lpj should probably become an implementation detail relevant to the CPU loop based delay routine only and more confined to it. In the mean time this is the minimal fix needed to have expected delays with the timer based implementation when cpufreq is also in use.

WARNING: at fs/btrfs/inode.c:7908 WARNING: at fs/btrfs/inode.c:7909 WARNING: at fs/btrfs/inode.c:7911 WARNING: at fs/btrfs/extent-tree.c:4510 WARNING: at fs/btrfs/extent-tree.c:4511 This problem was introduced by the patch "Btrfs: fix deadlock due to unsubmitted". In this patch, there are two bugs which caused the above problem. The 1st one is a off-by-one bug, if the DIO write return 0, it is also a short write, we need release the reserved space for it. But we didn't do it in that patch. Fix it by change "ret > 0" to "ret >= 0". The 2nd one is ->outstanding_extents was increased twice when a short write happened. As we know, ->outstanding_extents is a counter to keep track of the number of extent items we may use duo to delalloc, when we reserve the free space for a delalloc write, we assume that the write will introduce just one extent item, so we increase ->outstanding_extents by 1 at that time. And then we will increase it every time we split the write, it is done at the beginning of btrfs_get_blocks_direct(). So when a short write happens, we needn't increase ->outstanding_extents again. But this patch done. In order to fix the 2nd problem, I re-write the logic for ->outstanding_extents operation. We don't increase it at the beginning of btrfs_get_blocks_direct(), instead, we just increase it when the split actually happens.

Commit 99fc86450c439039d2ef88d06b222fd51a779176 "ALSA: usb-mixer: parse descriptors with structs" introduced a set of useful parsers for descriptors. Unfortunately the parses for the Processing Unit Descriptor came with a very subtle bug... Functions uac_processing_unit_iProcessing() and uac_processing_unit_specific() were indexing the baSourceID array forgetting the fields before the iProcessing and process-specific descriptors. The problem was observed with Sound Blaster Extigy mixer, where nNrModes in Up/Down-mix Processing Unit Descriptor was accessed at offset 10 of the descriptor (value 0) instead of offset 15 (value 7). In result the resulting control had interesting limit values: Simple mixer control 'Channel Routing Mode Select',0 Capabilities: volume volume-joined penum Playback channels: Mono Capture channels: Mono Limits: 0 - -1 Mono: -1 [100%] Fixed by starting from the bmControls, which was calculated correctly, instead of baSourceID.
