Makes more sense to group the entire mode_set stage into one function. Noticed while discussiing the rather confusing set of function names with Paulo Zanoni. Unfortunately I don't have an idea to make the function names lesss confusion. v2: Use for_each_encoder_on_crtc as suggested by Chris Wilson. Reviewed-by:

Fix support for all RGB/BGR pixel formats (except the 16:16:16:16 float format). Fix intel_init_framebuffer() to match hardware and driver limitations: * RGB332 is not supported at all * CI8 is supported * XRGB1555 & co. are supported on Gen3 and earlier * XRGB210101010 & co. are supported from Gen4 onwards * BGR formats are supported from Gen4 onwards * YUV formats are supported from Gen5 onwards (driver limitation) Signed-off-by:

In order to handle differences in pte encoding between architectures it is desirable to have one helper function, pte_encode, do it all for us. As such, this commit moves the code around so we're in good shape to do that. Luckily the ppgtt pte and the ggtt pte look very similar. Signed-off-by:

HSW will change the PTE encoding, and laying this out now will be helpful when we're ready to implement that. More importantly, GGTT and PPGTT PTE encoding is quite similar, so moving this out into a helper function will enable us to lance the AGP layer. Signed-off-by:

Now intel_ddi_init is just like intel_hdmi_init and intel_dp_init: it inits the encoder and then calls the proper init_connector functions. Notice that for non-eDP ports we call both HDMI and DP connector init, so we have 2 connectors attached to each DDI encoder. After this change, intel_hdmi_init and intel_dp_init are only called by Ivy Bridge and earlier, while hardware containing DDI outputs should call intel_ddi_init. Also added/removed quite a few "static" keywords due to the fact that some function pointers were moved from intel_dp.c and intel_hdmi.c to intel_ddi.c. DP finally works on Haswell now! \o/ Signed-off-by:

Both "intel_dp" and "intel_hdmi" structs had a "port" field, which always had the same value. It makes more sense to move this to intel_digital_port, so we can know the port independently of the connector type. Signed-off-by:

When intel_hdmi_detect detects a monitor, set intel_encoder->type with INTEL_OUTPUT_HDMI. Same for DP. This should not break the current code because these variables never change. This will be used after we create the DDI encoder because it will have both DP and HDMI connectors. We won't support eDP+HDMI on the same port, so if an encoder is eDP we should expect it to always remain eDP and never change. Signed-off-by:

Same reason as the previous HDMI commit: the DDI code will have its own encoder init function but still use the DP and HDMI connectors. Signed-off-by:

Paulo Zanoni authored
We want to split the HDMI connector and encoder initialization because in the future the DDI code will have its own "encoder init" function, but it will still call intel_hdmi_init_connector. The DDI encoder will actually have two connectors attached to it: HDMI and DP. The best way to look at this patch is to imagine that we're renaming intel_hdmi_init to intel_hdmi_init_connector and removing the encoder-specific pieces and placing them into intel_hdmi_init.

The goal is to have one single encoder capable of controlling both DP and HDMI outputs. This patch just adds the initial infrastructure, no functional changes. Previously, both intel_dp and intel_hdmi were intel_encoders. Now, these 2 structs do not have intel_encoder as members anymore. The new struct intel_digital_port has intel_encoder as a member, and it also includes intel_dp and intel_hdmi as members. In other words: see the changes inside intel_drv.h: it's the most important change, everything else is only to make it compile and work. For now, each intel_digital_port is still only able to control one of HDMI or DP, but not both together. In the future we should also try to merge the common fields from intel_dp and intel_hdmi (e.g., port). Signed-off-by:

When we add struct intel_digital_port, there will be no direct way of going from intel_{dp,hdmi} to drm_device: we will need to call container_of(). This patch adds functions to go from intel_{dp,hdmi} to drm_device. The main goal here is to greatly reduce the size of the next patch, where we will change the implementation of the functions we just added here (among other things).

- Replace container_of with enc_to_intel_dp. - Walk through less structures when making assignments. - Rename some variables to keep our naming standards. As a bonus, this will reduce the usage of "struct intel_dp", making the future patch that introduces intel_digital_port smaller and easier to review. Signed-off-by:

We were writing DSP_ADDR and DSP_SURF unconditionally. This did not trigger an unclaimed write before HSW as the address of DSP_ADDR has been repurposed as DSP_LINOFF. On HSW, though, DSP_LINOFF has been removed and then writting to it triggers an unclaimed write. This patch writes to DSP_ADDR or DSP_SURF to flush the display plane configuration depending on the gen we're running on. Signed-off-by:

And properly toggle the chicken bit in the pch to enable/disable fdi C rx. If we don't set this bit correctly, the rx gets confused in link training, which can result in an fdi link that silently fails to train the link (since the corresponding register reports success). Note that both fdi link B and C can suffer when this bit is not set correctly. The code as-is has a few deficiencies: - We presume all pipes use the pch which is not the case for cpu edp. - We don't bother with disabling both pipes when we could make things work, e.g. when pipe B switched from 4 to 2 lanes due to a mode change, we don't bother updating the w/a bit. - It's ugly. All of these are because we compute ->fdi_lanes way too late, when we're already setting up individual pipes. We need to have this information in ->modeset_global_resources already, to set things up correctly. But that is a much larger reorg of the code. Note that we actually hit the 2 lanes limit in practice rather quickly: Even though the 1920x1200 mode native mode of my screen fits into 2 lanes, it needs 3 lanes for the 1920x1080 (since that somehow has much more blanking ...). Not obeying this restriction seems to results in cute-looking digital noise. v2: Only ever clear the chicken bit when both pipes are off. v3: Use the new ->modeset_global_resources callback. v4: Move the WARNs to the right place. Oh how I hate hacks. v5: Fix spelling, noticed by Paulo Zanoni. Reviewed-by:

After all relevant pipes are disabled and after we've updated all the state with the staged state, but before we call the per-crtc ->mode_set functions there's a very natural point to set up any shared/global resources like - shared plls (obviously only the setup, the enabling needs to be separately handling with a separate refcount) - global watermark state like the DSPARB on gmch platforms - workaround bits that depend upon the exact global output configuration - enabling the right set of refclocks - enabling/disabling manual power wells. Now for a lot of these things we can't move them into this function yet, most often because we only compute the required information in the per-crtc ->mode_set callback. Which is too late. But due to a bunch of reasons (check-only atomic modeset, fastboot&hw state checks, ...) we need to separate the computation of that state from the actual hw frobbery anyway. So we can move things into this new callback step- by-step. Others can't be moved here (or implemented at all) because our code lacks the smarts to properly update them. E.g. the DSPARB can only be updated when all pipes are disabled, so if we decide to change it's value, we need to disable _all_ pipes. The infrastructure for that is already in place (with the various pipe masks that driver the modeset logic). But again we need to move a few things out of ->mode_set first before we can even implement the correct decision making. In any case, we need to start somewhere, so let's start with the callback: Some small follow-up patches will make immediate good use of it. Reviewed-by:

Atm we have a few funny issues where we enable/disable shared pll clocks. To make it clear that we are not required to enable/ disable the pch plls together with the other pch resources (and so should keep it running when it's used by another pipe in a shared pll configuration) add a comment. This note is lifted from "Graphics BSpec: vol4g North Display Engine Registers [IVB], Display Mode Set Sequence", step 9.d. of the enable sequence: "Configure and enable PCH DPLL, wait for PCH DPLL warmup (Can be done anytime before enabling PCH transcoder)." Since fixing the pll sharing code to no longer disable shared plls if they're still in use is more involved, let's just stick with the comment for now. v2: Make the comment in the code clearer, to address questions raised by Paulo Zanoni in review.

My machine here has the correct ones already, but better safe than sorry. IBX has different settings for that register, and on IBX the device defaults match the recommended values. Hence I did not add the respective writes for IBX.

According to "Graphics BSpec: vol4g North Display Engine Registers [IVB], Display Mode Set Sequence" We need to write the TU size register of the fdi RX unit _before_ starting to train the link. Note: The current code is actually correct as Paulo mentioned in review, but it's a bit confusion since only the fdi rx/tx plls need to be enabled before the cpu pipes/planes. Hence it's still a good idea to move the TU_SIZE setting to the "right" spot in the sequence, to better match Bspec. Reviewed-by:
