We already have the code to calculate the WRPLL output clock from the register values, but for some reason we're only using it for HDMI and not DP. Throw out the inflexible DP DPLL table lookup and just call the HDMI code which decodes the actual register values. Signed-off-by:

For virtual engines, we need to keep the HW context alive while it remains in use. For regular HW contexts, they are created and kept alive until the end of the GEM context. For simplicity, generalise the requirements and keep an active reference to each HW context. Signed-off-by:

We no longer allow mixed C99 and kernel types, and the preference is to use kernel types exclusively. Fix the C99 types that have crept in since the mass conversion. No functional changes.

As the final request on a ring may hold the reference to this ring (via retiring the last pinned context), we may find ourselves chasing a dangling pointer on completion of the list. A quick solution is to hold a reference to the ring itself as we retire along it so that we only free it after we stop dereferencing it. Signed-off-by:

If we use the STORE_DATA_INDEX function we can use a fixed offset and avoid having to lookup up the engine HWS address. A step closer to being able to emit the final breadcrumb during request_add rather than later in the submission interrupt handler. Signed-off-by:

We're currently leaving the CUS enabled if we disable the master plane directly after scanning out NV12. Could perhaps cause the selected slave plane to misbehave if we try to use it for scanning out something non-NV12? Signed-off-by:

We must remember to actually enable the post CSC gamma if we expect the legacy LUT to work. Seems to fix NV12 crc tests on the SDR planes. Curiously we apparently managed to get 100% match for the HDR planes even without chopping off the low bits. Cc: Uma Shankar <uma.shankar@intel.com> Signed-off-by:

Slightly verbose, but does away with hand rolled shifts. Ties the field values with the mask defining the field. Unfortunately we have to make a local copy of FIELD_PREP() to evaluate to a integer constant expression. But with this, we can ensure the mask is non-zero, power of 2, fits u32, and the value fits the mask (when the value is a constant expression). Convert power sequencer registers as an example. v4: - rebase v3: - rename the macro to REG_FIELD_PREP to avoid underscore prefix and to be in line with kernel macros (Chris) - rename power of 2 check macro (Chris) v2: - add build-time checks with BUILD_BUG_ON_ZERO() - rename to just _FIELD() due to regmap.h REG_FIELD() clash Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

bitfield.h defines FIELD_GET() and FIELD_PREP() macros to access bitfields using the mask alone, with no need for separate shift. Indeed, the shift is redundant. We define REG_FIELD_GET() and REG_FIELD_PREP() wrappers for the above, in part to force u32 and for consistency with REG_BIT() and REG_GENMASK(), but also as we'll need to redefine REG_FIELD_PREP() in follow-up work to make it produce integer constant expressions. For the most part, REG_FIELD_GET() is shorter than masking followed by shift, and arguably has more clarity. REG_FIELD_PREP() can get more verbose than simply shifting in place, but it does provide masking to ensure we don't overflow the mask, something we usually don't bother with currently. Convert power sequencer registers as an example. v3: - temp variable removal (Chris) - rebase v2: - Add the REG_FIELD_GET() and REG_FIELD_PREP() wrappers to use them consistently from the start.

Introduce REG_BIT(n) to define register bits and REG_GENMASK(h, l) to define register bitfield masks. We define the above as wrappers to BIT() and GENMASK() respectively to force u32 type to go with our register size, and to add compile time checks on the bit numbers. The intention is that these are easier to get right and review against the spec than hand rolled masks. Convert power sequencer registers as an example. v4: - rebase v3: - rename macros to REG_BIT() and REG_GENMASK() to avoid underscore prefix and to be in line with kernel macros (Chris) - add compile time checks (Mika) v2: - rename macros to just _BIT() and _MASK() to reduce verbosity Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

We only need to acquire a wakeref for ourselves for a few operations, as most either already acquire their own wakeref or imply a wakeref. In particular, it is i915_gem_set_wedged() that needed us to present it with a wakeref, which is incongruous with its "use anywhere" ability. Suggested-by:

We assumed that vm_mmap() would reject an attempt to mmap past the end of the filp (our object), but we were wrong. Applications that tried to use the mmap beyond the end of the object would be greeted by a SIGBUS. After this patch, those applications will be told about the error on creating the mmap, rather than at a random moment on later access. Reported-by:

Split the csc matrix handling to ilk+ and icl+ functions. This keeps the logic clear on what is loaded into which CSC unit on the hardware. We also fix the icl+ code to load the full->limited range conversion matrix into the output CSC rather than the pipe CSC which was used on earlier platforms. And we also turn on the pipe CSC only when the ctm is present. Signed-off-by:

Let's start using the vfuncs to differentiate MG and Combo PLLs. The end goal is to decouple the type of the PLL from the IDs since the latter are likely to change from one platform to another.
