2013-05-11qlcnic: Fix reset recovery after transmit timeoutSony Chacko
o When transmit timeout happens, recovery attempt should start with adapter soft reset. If soft reset fails to resume traffic, firmware dump will be collected and driver will perform a hard reset of the adapter. Reset recovery on 83xx was failing after a hard reset.

2013-05-11parisc: fix SMP races when updating PTE and TLB entries in entry.SJohn David Anglin
Currently, race conditions exist in the handling of TLB interruptions in entry.S. In particular, dirty bit updates can be lost if an accessed interruption occurs just after the dirty bit interruption on a different cpu. Lost dirty bit updates result in user pages not being flushed and general system instability. This change adds lock and unlock macros to synchronize all PTE and TLB updates done in entry.S. As a result, userspace stability is significantly improved. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>
2013-05-11parisc: implement irq stacks - part 2 (v2)Helge Deller
This patch fixes few build issues which were introduced with the last irq stack patch, e.g. the combination of stack overflow check and irq stack. Furthermore we now do proper locking and change the irq bh handler to use the irq stack as well. In /proc/interrupts one now can monitor how huge the irq stack has grown and how often it was preferred over the kernel stack. IRQ stacks are now enabled by default just to make sure that we not overflow the kernel stack by accident. Signed-off-by: Helge Deller <deller@gmx.de>

2013-05-10drm/i915: Add support for FBC on Ivybridge.Rodrigo Vivi
This patch introduce Frame Buffer Compression (FBC) support for IVB, without enabling it by default. It adds a new function gen7_enable_fbc to avoid getting ironlake_enable_fbc messed with many IS_IVYBRIDGE checks. v2: Fixes from Ville. * Fix Plane. FBC is tied to primary plane A in HSW * Fix DPFC initial write to avoid let trash on the register. v3: Checking for bad plane on intel_update_fbc() as Chris suggested. v4: Ville pointed out that according to BSpec FBC_CTL bits 0:3 must be 0. v5: Up to v4 this work was entirely focused on Haswell. However Ville noticed I could reuse the FBC work done for HSW and get FBC for free at Ivybridge. So it makes more sense enable FBC for IVB first. FBC for HSW comming on next patches. We are just not enabling it by default on IVB. v6: Fix confused commit name (by Matt Turner). v7: Remove gtt_offset shift since it is page aligned byte offset (by Ville).

2013-05-10drm/i915: rip out TV-out lore ...Daniel Vetter
This seems to be an impressive piece of copy&pasta lore. I've checked all docs and on most platforms these bits are all MBZ, with the exception of the SDVO pixel multiplier on gen3. On gen4 that moved to a special DPLL_MD registers. No indication whatsoever that we actually need this for native TV-out support. I suspect this started as a hack when we didn't yet have proper pixel multiplier support in place for SDVO TV, but then got stuck in a life of its own. Just rip it out.

2013-05-10drm/i915: drop TVclock special casing on ilk+Daniel Vetter
TV-out uses the same reference clock as everyone else. The only difference seems to be in the slightly different CB tuning limit. Note that PLL_REF_INPUT_TVCLKINBC is a reserved value on ilk+. Also strictly speaking we don't support native TV-out on ilk+, hence all that code is dead. But Bspec still contains some residual mentions of native TV-out on some pch-split platforms, so I've figured it doesn't hurt to keep the code around a bit longer (e.g. in the cb tune function). v2: Improve the commit message as Jani suggested in his review.

We have a very nice infrastructure for this now! Note that the multifunction sdvo support is pretty neatly broken: We completely ignore userspace's request for which connector to wire up with the encoder and just use whatever the last detect callback has seen. Not something I'll fix in this patch, but unfortunately something which is also broken in the DDI code ... v2: Don't call sdvo_tv_clock twice.

This should replace intel_using_power_well. The idea is that we're adding the requested power domain as an argument, so this might enable the code to look less platform-specific and also allows us to easily add new domains in case we need. v2: Add more domains to enum intel_display_power_domain v3: Even more domains requested Requested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-05-10drm/i915: set proper DPIO post divider for VGA on VLV v4Jesse Barnes
Supposedly we should use the DAC divider for <300MHz pixel clocks, but as that doesn't actually work as well as the high freq divider here in practice, just use the high freq divider all the time. v2: remove unconditional write (Jesse) check for pixel rate properly (Jesse) v3: give up, the DAC divider apparently doesn't work, and low res modes work ok (Jesse) remove debug msg (Jesse) Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Tested-by: Kenneth Graunke <kenneth@whitecape.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-05-10drm/i915: fix panel fitting on LVDS on ILK+ v2Jesse Barnes
This regression was introduced in: commit b074cec8c652f2d273907a4b35239b4766c894ac Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Thu Apr 25 12:55:02 2013 -0700 drm/i915: move PCH pfit controls into pipe_config In refactoring this, it was only applied to eDP, which is incorrect. In fact, if we ever use the panel fitter to deal with overscan on HDMI, we'll need to extend it again, so just drop the conditional altogether. v2: drop check for eDP since we can use the fitter in any config (Daniel) Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-05-10drm/i915: go back to switch for VLV mem freq detection v2Jesse Barnes
Both the docs and the existing code were wrong. So fix both and use a switch statement like we do elsewhere to make things simple & clear. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-by: Ben Widawsky <ben@bwidawsk.net> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
