Move all of the constant assignments up front and into a common function. This is primarily to ensure the backpointers are set as early as possible for later use during initialisation. v2: Use a constant struct so that all the similar values are set together. v3: Sanitize the engine's IMR to disable any potential interrupt before we are ready (enabled in init_hw). v4: Ignore the engine's IMR, to be resolved later Signed-off-by:

I have noticed some of our interrupt handlers use both dev and dev_priv while they could get away with only dev_priv in the huge majority of cases. Tidying that up had a cascading effect on changing functions prototypes, so relatively big churn factor, but I think it is for the better. For example even where changes cascade out of i915_irq.c, for functions prefixed with intel_, genX_ or <plat>_, it makes more sense to take dev_priv directly anyway. This allows us to eliminate local variables and intermixed usage of dev and dev_priv where only one is good enough. End result is shrinkage of both source and the resulting binary. i915.ko: - .text 000b0899 + .text 000b0619 Or if we look at the Gen8 display irq chain: -00000000000006ad t gen8_irq_handler +0000000000000663 t gen8_irq_handler -0000000000000028 T intel_opregion_asle_intr +0000000000000024 T intel_opregion_asle_intr -000000000000008c t ilk_hpd_irq_handler +000000000000007f t ilk_hpd_irq_handler -0000000000000116 T intel_check_page_flip +0000000000000112 T intel_check_page_flip -000000000000011a T intel_prepare_page_flip +0000000000000119 T intel_prepare_page_flip -0000000000000014 T intel_finish_page_flip_plane +0000000000000013 T intel_finish_page_flip_plane -0000000000000053 t hsw_pipe_crc_irq_handler +000000000000004c t hsw_pipe_crc_irq_handler -000000000000022e t cpt_irq_handler +0000000000000213 t cpt_irq_handler So small shrinkage but it is all fast paths so doesn't harm.

DP dual mode type 1 DVI adaptors aren't required to implement any registers, so it's a bit hard to detect them.

Try to detect the max TMDS clock limit for the DP++ adaptor (if any) and take it into account when checking the port clock. Note that as with the sink (HDMI vs. DVI) TMDS clock limit we'll ignore the adaptor TMDS clock limit in the modeset path, in case users are already "overclocking" their TMDS links. One subtle change here is that we'll have to respect the adaptor TMDS clock limit when we decide whether to do 12bpc or 8bpc, otherwise we might end up picking 12bpc and accidentally driving the TMDS link out of spec even when the user chose a mode that fits wihting the limits at 8bpc. This means you can't "overclock" your DP++ dongle at 12bpc anymore, but you can continue to do so at 8bpc. Note that for simplicity we'll use the I2C access method for all dual mode adaptors including type 2. Otherwise we'd have to start mixing DP AUX and HDMI together. In the future we may need to do that if we come across any board designs that don't hook up the DDC pins to the DP++ connectors. Such boards would obviously only work with type 2 dual mode adaptors, and not type 1. v2: Store adaptor type under indel_hdmi->dp_dual_mode Deal with DRM_DP_DUAL_MODE_UNKNOWN Pass adaptor type to drm_dp_dual_mode_max_tmds_clock(), and use it for type1 adaptors as well Cc: stable@vger.kernel.org Reported-by:

Ville Syrjälä authored
Add a helper which aids in the identification of DP dual mode (aka. DP++) adaptors. There are several types of adaptors specified: type 1 DVI, type 1 HDMI, type 2 DVI, type 2 HDMI Type 1 adaptors have a max TMDS clock limit of 165MHz, type 2 adaptors may go as high as 300MHz and they provide a register informing the source device what the actual limit is. Supposedly also type 1 adaptors may optionally implement this register. This TMDS clock limit is the main reason why we need to identify these adaptors. Type 1 adaptors provide access to their internal registers and the sink DDC bus through I2C. Type 2 adaptors provide this access both via I2C and I2C-over-AUX. A type 2 source device may choose to implement either of these methods. If a source device implements the I2C-over-AUX method, then the driver will obviously need specific support for such adaptors since the port is driven like an HDMI port, but DDC communication happes over the AUX channel. This helper should be enough to identify the adaptor type (some type 1 DVI adaptors may be a slight exception) and the maximum TMDS clock limit. Another feature that may be available is control over the TMDS output buffers on the adaptor, possibly allowing for some power saving when the TMDS link is down. Other user controllable features that may be available in the adaptors are downstream i2c bus speed control when using i2c-over-aux, and some control over the CEC pin. I chose not to provide any helper functions for those since I have no use for them in i915 at this time. The rest of the registers in the adaptor are mostly just information, eg. IEEE OUI, hardware and firmware revision, etc. v2: Pass adaptor type to helper functions to ease driver implementation Fix a bunch of typoes (Paulo) Add DRM_DP_DUAL_MODE_UNKNOWN for the case where we don't (yet) know the type (Paulo) Reject 0x00 and 0xff DP_DUAL_MODE_MAX_TMDS_CLOCK values (Paulo) Adjust drm_dp_dual_mode_detect() type2 vs. type1 detection to ease future LSPCON enabling Remove the unused DP_DUAL_MODE_LAST_RESERVED define v3: Fix kernel doc function argument descriptions (Jani) s/NONE/UNKNOWN/ in drm_dp_dual_mode_detect() docs Add kernel doc for enum drm_dp_dual_mode_type Actually build the docs Fix more typoes v4: Adjust code indentation of type2 adaptor detection (Shashank) Add debug messages for failurs cases (Shashank) v5: EXPORT_SYMBOL(drm_dp_dual_mode_read) (Paulo) Cc: stable@vger.kernel.org Cc: Tore Anderson <tore@fud.no> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Shashank Sharma <shashank.sharma@intel.com> Signed-off-by:

For legacy ringbuffer mode, we need the new ordered breadcrumb emission tried and tested on execlists in order to avoid the dreaded "missed interrupt" syndrome. A secondary advantage of the execlists method is that it writes to an arbitrary address, useful if one wants to write a breadcrumb elsewhere. This fix is taken from commit 7c17d377 (drm/i915: Use ordered seqno write interrupt generation on gen8+ execlists). Signed-off-by:

At the start of request emission, we flush some space for the request, estimating the typical size for the request body. The common tail is now much larger than the typical body, so we can shrink the flush substantially. Signed-off-by:

With 5 rings and a flush, we need 192 bytes of space to emit the breadcrumb and semaphores. However, we need some spare room the size of the single largest packet (36 dwords, 144 bytes) to accommodate wraparound giving a grand total of 336 bytes Signed-off-by:

The code used by the DP and HDMI paths was very similar, so make them share it. Note that this removes the write to signal level registers from the HDMI pre pll enable path, but that's OK since those are set in vlv_hdmi_pre_enable() function. Signed-off-by:

The logic for setting signal levels is used for both HDMI and DP with small variations. But it is similar enough to put behind a function called from the encoders. v2: Remove unrelated MST changes due to rebase fumble. (Jim Bride) Fix typo in the commit message. (Jim Bride) v3: Really fix the typo. (Jim) Cc: Jim Bride <jim.bride@linux.intel.com> Signed-off-by:

The exact same code was used by HDMI and DP encoders, so move it to intel_dpio_phy.c. v2: Fix typo in the commit message. (Jim Bride) v3: Call the new function chv_phy_post_pll_disable() instead of chv_phy_post_disable(), as it should be called after the pll is disabled.
