2014-04-02drm/i915: fix infinite loop at gen6_update_ring_freqPaulo Zanoni
If I boot my Broadwell machine to X on a system with Mesa Gallium llvmpipe instead of i965, then kill X and try to run pm_pc8.c, when we disable PC8 and call gen6_update_ring_freq(), we will get stuck on an infinite loop because the frequencies are zero and the variables are unsigned. This happens because we never ran any batch, so we did not enable RC6, so the variables are zero. If I run gem_exec_nop before running pm_pc8, everything works as expected because gem_exec_nop makes RC6 be enabled. This commit should prevent the infinite loop, which IMHO is already a good reason to be merged, but it is not the proper fix to the "RC6 is not being enabled" problem.

2014-04-02drm/i915: Track OACONTROL register enable/disable during parsingBrad Volkin
There is some thought that the data from the performance counters enabled via OACONTROL should only be available to the process that enabled counting. To limit snooping, require that any batch buffer which sets OACONTROL to a non-zero value also sets it back to 0 before the end of the batch. This requires limiting OACONTROL writes to happen via MI_LOAD_REGISTER_IMM so that we can access the value being written.

2014-04-02drm/crtc-helper: don't disable disconnected outputsDaniel Vetter
This is the equivalent change in the crtc helpers as done to the i915 modeset infrastructure in commit b0a2658acb5bf9ca86b4aab011b7106de3af0add Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Dec 18 09:37:54 2012 +0100 drm/i915: don't disable disconnected outputs This was originally introduced to make encoder sharing on radone easier for userspace, but: - It is policy and as such belongs into userspace. E.g. personally I'm fairly annoyed that a flaky cable results in permanent changes of the desktop layout, so I'll kick out DEs which do this. Worse if the kernel also tries to be clever. - It's inconsistent: We only kill disconnected outputs on setCrtc (which userspace might also call when just changing the framebuffer), but not when e.g. we receive a hpd event or in the output poll worker. - It's unexpected behaviour for the userspace driver, at least in the intel ddx we've had tons of bugs where the driver fell over and killed the X session becuase pageflips/vblanks suddenly stopped working. We've had to fix this by wrapping every single setCrtc int a big "recover kms state from the kernel again" operation. - It's suprising for the kernel, too: It took a few mails between Rob, Matt and me for them to notice that little dragon wreaking havoc with the universal plane framebuffer refcounting. - Userspace can cope with it and e.g. Gnome already kills disconnected outputs and reconfigures the desktop automatically. And since there have been no regression reports for the i915 change from over 1 year ago I think all other DEs are also ready.

2014-04-01drm/i915: only enable HWSTAM interrupts on postinstall on ILK+Paulo Zanoni
We should only enable interrupts at postinstall. And now on ILK/SNB/IVB/HSW the irq_preinstall and irq_postinstall functions leave the hardware in the same state.

2014-04-01drm/i915: add ironlake_irq_resetPaulo Zanoni
To merge the common code of ironlake_irq_preinstall and ironlake_irq_uninstall. We should also probably do something about that HSWSTAM write on a later commit.

2014-04-01drm/i915: remove ibx_irq_uninstallPaulo Zanoni
After the latest changes, ibx_irq_preinstall and ibx_irq_uninstall are the same, so remove one of the copies and rename the other to ibx_irq_reset (since we're using the "reset" name for things which are called both at preinstall and uninstall). v2: - Rebase.
