set_page_dirty says: For pages with a mapping this should be done under the page lock for the benefit of asynchronous memory errors who prefer a consistent dirty state. This rule can be broken in some special cases, but should be better not to. Under those rules, it is only safe for us to use the plain set_page_dirty calls for shmemfs/anonymous memory. Userptr may be used with real mappings and so needs to use the locked version (set_page_dirty_lock).

If we setup backing phys page for 3lvl pdps, as they are not used, we will lose 5 pages per ppgtt. Trading this memory on bsw, we gain more common code paths for all gen8+ directory manipulation.

Mika Kuoppala authored
For all page directory entries, the pde encoding is identical. Don't complicate call sites with different versions of doing the same thing, so we always check the existence of physical page before writing the entry into it. This further generalizes the pd so that manipulation in callsites will be identical, removing the need to handle pdps differently for gen8. v2: squash v3: inc/dec with set/clear (Chris) v4: inlines, warn, stray set_pd (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Matthew Auld <matthew.auld@intel.com> Signed-off-by:

This patch adds support for DPLL4 on EHL that include the following restrictions: - DPLL4 cannot be used with DDIA (combo port A internal eDP usage). DPLL4 can be used with other DDIs, including DDID (combo port A external usage). - DPLL4 cannot be enabled when DC5 or DC6 are enabled. - The DPLL4 enable, lock, power enabled, and power state are connected to the MGPLL1_ENABLE register. v2: (suggestions from Bob Paauwe) - Rework ehl_get_dpll() function to call intel_find_shared_dpll() and iterate twice: once for Combo plls and once for MG plls. - Use MG pll funcs for DPLL4 instead of creating new ones and modify mg_pll_enable to include the restrictions for EHL. v3: Fix compilation error v4: (suggestions from Lucas and Ville) - Treat DPLL4 as a combo phy PLL and not as MG PLL - Disable DC states when this DPLL is being enabled - Reuse icl_get_dpll instead of creating a separate one for EHL v5: (suggestion from Ville) - Refcount the DC OFF power domains during the enabling and disabling of this DPLL. v6: rebase v7: (suggestion from Imre) - Add a new power domain instead of iterating over the domains assoicated with DC OFF power well. v8: (Ville and Imre) - Rename POWER_DOMAIN_DPLL4 TO POWER_DOMAIN_DPLL_DC_OFF - Grab a reference in intel_modeset_setup_hw_state() if this DPLL was already enabled perhaps by BIOS. - Check for the port type instead of the encoder v9: (Ville) - Move the block of code that grabs a reference to the power domain POWER_DOMAIN_DPLL_DC_OFF to intel_modeset_readout_hw_state() to ensure that there is a reference present before this DPLL might get disabled. v10: rebase Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Imre Deak <imre.deak@intel.com> Signed-off-by:

Split the format lists for different planes on skl/icl more cleanly. On skl+ we have just two types of planes: those can do planar and those that can't. On icl we have three types of planes: hdr planes, sdr planes that can do planar, and sdr planes that can't do planar. Those latter two are the same set of planes we must when choose from when picking the UV vs. Y plane for planar scanout. So we shall just designate them sdr uv planes and sdr y planes. Reviewed-by:

Docs tell us that on g4x we have to compute the SR watermarks using 4 bytes per pixel. I'm going to assume that only applies to 1 and 2 byte per pixel formats, and not 8 byte per pixel formats. That seems like a recipe for an insufficient watermark which could lead to underruns. Use the maximum of the two numbers instead. Reviewed-by:

All sprite planes have a progammable gamma ramp. Set it up with a linear ramp on all platforms. This actually matches the reset value but soon we'll want to reprogram this ramp on some machines, so let's just set it up across the board. Note that on pre-IVB the hardware bypasses the gamma unit unless a YCbCr pixel format is used. v2: Add parens around << in ilk_linear_gamma() Skip gamma programming for RGB on pre-IVB s/DVSGAMC/DVSGAMC_G4X/ Reviewed-by: -

We don't currently have any use for the sprite gamma on ivb-bdw. Let's disable it. We already do that on skl+. On pre-ivb there is no way to disable the sprite gamma, and it only affects YCbCr pixel formats, whereas on ivb+ it also affects RGB formats. Reviewed-by:

Plane B and C (note that we don't actually expose plane C currently) on gen2/3 have a window generator, as does the primary plane on CHV pipe B. So let's allow positioning of these planes freely within the pipe source area. Plane A on gen2/3 seems to have some kind of partial window generator which would allow you to cut the plane off midway through the scanout, but it would still have to start at the top-left corner of the pipe, and it would have to be full width. That's doesn't sound all that useful, so for simplicity let's just keep to the idea that plane A has to be fullscreen. Gen4 removed the plane A/B windowing support entirely, and it wasn't reintroduced until SKL (apart from the CHV pipe B special case). v2: s/plane/i9xx_plane/ etc. (James) v3: Make it less confusing v4: Deal with IS_GEN() Reviewed-by:

It seems intel_engine_get_instdone is able to get instdone for all engines but intel_hangcheck.c/subunits_stuck decides to ignore it for non render. We can just drop the check in subunits_stuck since the checks on unavailable fields will always return stuck, which when bitwise and with the potential unstuck instdone is harmless. Signed-off-by:

Since reservation_object_fini() does an immediate free, rather than kfree_rcu as normal, we have to delay the release until after the RCU grace period has elapsed (i.e. from the rcu cleanup callback) so that we can rely on the RCU protected access to the fences while the object is a zombie. i915_gem_busy_ioctl relies on having an RCU barrier to protect the reservation in order to avoid having to take a reference and strong memory barriers. v2: Order is important; only release after putting the pages!
