2013-03-21drm/mgag200: Bug fix: Modified pll algorithm for EH projectJulia Lemire
While testing the mgag200 kms driver on the HP ProLiant Gen8, a bug was seen. Once the bootloader would load the selected kernel, the screen would go black. At first it was assumed that the mgag200 kms driver was hanging. But after setting up the grub serial output, it was seen that the driver was being loaded properly. After trying serval monitors, one finaly displayed the message "Frequency Out of Range". By comparing the kms pll algorithm with the previous mgag200 xorg driver pll algorithm, discrepencies were found. Once the kms pll algorithm was modified, the expected pll values were produced. This fix was tested on several monitors of varying native resolutions. Signed-off-by: Julia Lemire <jlemire@matrox.com> Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-03-20dm cache: policy ignore hints if generated by different versionMike Snitzer
When reading the dm cache metadata from disk, ignore the policy hints unless they were generated by the same major version number of the same policy module. The hints are considered to be private data belonging to the specific module that generated them and there is no requirement for them to make sense to different versions of the policy that generated them. Policy modules are all required to work fine if no previous hints are supplied (or if existing hints are lost).

2013-03-20dm cache: fix race in writethrough implementationJoe Thornber
We have found a race in the optimisation used in the dm cache writethrough implementation. Currently, dm core sends the cache target two bios, one for the origin device and one for the cache device and these are processed in parallel. This patch avoids the race by changing the code back to a simpler (slower) implementation which processes the two writes in series, one after the other, until we can develop a complete fix for the problem. When the cache is in writethrough mode it needs to send WRITE bios to both the origin and cache devices. Previously we've been implementing this by having dm core query the cache target on every write to find out how many copies of the bio it wants. The cache will ask for two bios if the block is in the cache, and one otherwise. Then main problem with this is it's racey. At the time this check is made the bio hasn't yet been submitted and so isn't being taken into account when quiescing a block for migration (promotion or demotion). This means a single bio may be submitted when two were needed because the block has since been promoted to the cache (catastrophic), or two bios where only one is needed (harmless). I really don't want to start entering bios into the quiescing system (deferred_set) in the get_num_write_bios callback. Instead this patch simplifies things; only one bio is submitted by the core, this is first written to the origin and then the cache device in series. Obviously this will have a latency impact. deferred_writethrough_bios is introduced to record bios that must be later issued to the cache device from the worker thread. This deferred submission, after the origin bio completes, is required given that we're in interrupt context (writethrough_endio).

2013-03-20dm verity: avoid deadlockMikulas Patocka
A deadlock was found in the prefetch code in the dm verity map function. This patch fixes this by transferring the prefetch to a worker thread and skipping it completely if kmalloc fails. If generic_make_request is called recursively, it queues the I/O request on the current->bio_list without making the I/O request and returns. The routine making the recursive call cannot wait for the I/O to complete. The deadlock occurs when one thread grabs the bufio_client mutex and waits for an I/O to complete but the I/O is queued on another thread's current->bio_list and is waiting to get the mutex held by the first thread. The fix recognises that prefetching is not essential. If memory can be allocated, it queues the prefetch request to the worker thread, but if not, it does nothing.

2013-03-20dm thin: fix non power of two discard granularity calcJoe Thornber
Fix a discard granularity calculation to work for non power of 2 block sizes. In order for thinp to passdown discard bios to the underlying data device, the data device must have a discard granularity that is a factor of the thinp block size. Originally this check was done by using bitops since the block_size was known to be a power of two. Introduced by commit f13945d75730081830b6f3360266950e2b7c9067 ("dm thin: support a non power of 2 discard_granularity").

2013-03-20dm thin: fix discard corruptionJoe Thornber
Fix a bug in dm_btree_remove that could leave leaf values with incorrect reference counts. The effect of this was that removal of a shared block could result in the space maps thinking the block was no longer used. More concretely, if you have a thin device and a snapshot of it, sending a discard to a shared region of the thin could corrupt the snapshot. Thinp uses a 2-level nested btree to store it's mappings. This first level is indexed by thin device, and the second level by logical block. Often when we're removing an entry in this mapping tree we need to rebalance nodes, which can involve shadowing them, possibly creating a copy if the block is shared. If we do create a copy then children of that node need to have their reference counts incremented. In this way reference counts percolate down the tree as shared trees diverge. The rebalance functions were incrementing the children at the appropriate time, but they were always assuming the children were internal nodes. This meant the leaf values (in our case packed block/flags entries) were not being incremented.

2013-03-20drm/i915: stop using GMBUS IRQs on Gen4 chipsJiri Kosina
Commit 28c70f162 ("drm/i915: use the gmbus irq for waits") switched to using GMBUS irqs instead of GPIO bit-banging for chipset generations 4 and above. It turns out though that on many systems this leads to spurious interrupts being generated, long after the register write to disable the IRQs has been issued. Typically this results in the spurious interrupt source getting disabled: [ 9.636345] irq 16: nobody cared (try booting with the "irqpoll" option) [ 9.637915] Pid: 4157, comm: ifup Tainted: GF 3.9.0-rc2-00341-g0863702 #422 [ 9.639484] Call Trace: [ 9.640731] <IRQ> [<ffffffff8109b40d>] __report_bad_irq+0x1d/0xc7 [ 9.640731] [<ffffffff8109b7db>] note_interrupt+0x15b/0x1e8 [ 9.640731] [<ffffffff810999f7>] handle_irq_event_percpu+0x1bf/0x214 [ 9.640731] [<ffffffff81099a88>] handle_irq_event+0x3c/0x5c [ 9.640731] [<ffffffff8109c139>] handle_fasteoi_irq+0x7a/0xb0 [ 9.640731] [<ffffffff8100400e>] handle_irq+0x1a/0x24 [ 9.640731] [<ffffffff81003d17>] do_IRQ+0x48/0xaf [ 9.640731] [<ffffffff8142f1ea>] common_interrupt+0x6a/0x6a [ 9.640731] <EOI> [<ffffffff8142f952>] ? system_call_fastpath+0x16/0x1b [ 9.640731] handlers: [ 9.640731] [<ffffffffa000d771>] usb_hcd_irq [usbcore] [ 9.640731] [<ffffffffa0306189>] yenta_interrupt [yenta_socket] [ 9.640731] Disabling IRQ #16 The really curious thing is now that irq 16 is _not_ the interrupt for the i915 driver when using MSI, but it _is_ the interrupt when not using MSI. So by all indications it seems like gmbus is able to generate a legacy (shared) interrupt in MSI mode on some configurations. I've tried to reproduce this and the differentiating thing seems to be that on unaffected systems no other device uses irq 16 (which seems to be the non-MSI intel gfx interrupt on all gm45). I have no idea how that even can happen. To avoid tempting this elephant into a rage, just disable gmbus interrupt support on gen 4. v2: Improve the commit message with exact details of what's going on. Also add a comment in the code to warn against this particular elephant in the room. v3: Move the comment explaing how gen4 blows up next to the definition of HAS_GMBUS_IRQ to keep the code-flow straight.

2013-03-19PCI: Use ROM images from firmware only if no other ROM source availableMatthew Garrett
Mantas Mikulėnas reported that his graphics hardware failed to initialise after commit f9a37be0f02a ("x86: Use PCI setup data"). The aim of this commit was to ensure that ROM images were available on some Apple systems that don't expose the GPU ROM via any other source. In this case, UEFI appears to have provided a broken ROM image that we were using even though there was a perfectly valid ROM available via other sources. The simplest way to handle this seems to be to just re-order pci_map_rom() and leave any firmare-supplied ROM to last.

2013-03-18drm/i915: Use the fixed pixel clock for eDP in intel_dp_set_m_n()Takashi Iwai
The eDP output on HP Z1 is still broken when X is started even after fixing the infinite link-train loop. The regression was introduced in 3.6 kernel for cleaning up the mode clock handling code in intel_dp.c by the commit [71244653: drm/i915: adjusted_mode->clock in the dp mode_fix]. In the past, the clock of the reference mode was modified in intel_dp_mode_fixup() in the case of eDP fixed clock, and this clock was used for calculating in intel_dp_set_m_n(). This override was removed, thus the wrong mode clock is used for the calculation, resulting in a psychedelic smoking output in the end. This patch corrects the clock to be used in the place. v1->v2: Use intel_edp_target_clock() for checking eDP fixed clock instead of open code as in ironlake_set_m_n().

2013-03-18drm/nouveau/therm: do not make assumptions on temperatureMartin Peres
In nouveau_therm_sensor_event, temperature is stored as an uint8_t even though the original interface returns an int.

2013-03-18drm/nv40/therm: increase the sensor's settling delay to 20msMartin Peres
Based on my experience, 10ms wasn't always enough. Let's bump that to a little more. If this turns out to be insufficient-enough again, then an approach based on letting the sensor settle for several seconds before starting polling on the temperature would be better suited. This way, boot time wouldn't be impacted by those waits too much. Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-03-18drm/nv40/therm: improve selection between the old and the new styleMartin Peres
The condition to select between the old and new style was a thinko as rnndb orders chipsets based on their release date (or general chronologie hw-wise) and not based on their chipset number. As the nv40 family is a mess when it comes to numbers, this patch introduces a switch-based selection between the old and new style.

2013-03-17Revert "drm/i915: try to train DP even harder"Takashi Iwai
This reverts commit 0d71068835e2610576d369d6d4cbf90e0f802a71. Not only that the commit introduces a bogus check (voltage_tries == 5 will never meet at the inserted code path), it brings the i915 driver into an endless dp-train loop on HP Z1 desktop machine with IVY+eDP. At least reverting this commit recovers the framebuffer (but X is still broken by other reasons...)

Regarding the Bluetooth bits, Gustavo says: "I have these two patches for 3.9, these add support for two more devices to the bluetooth drivers." Along with those, we have a few wireless driver fixes... Bing Zhao provides an mwifiex to prevent an out-of-bounds memory access. John Crispin offers a Kconfig fix to enable some otherwise dead code in rt2x00. The correct symbols were added in -rc1 through a different tree, but the symbols for enabling the wireless driver didn't match. Larry Finger brings an rtlwifi fix for a scheduling while atomic bug, and another fix for a reassociation problem caused by failing to clear the BSSID after a disconnect. ==================== Signed-off-by: David S.
