* drm/msm: shrinker supportRob Clark2016-07-161-0/+1
| | | | | | | | For a first step, only purge obj->madv==DONTNEED objects. We could be more agressive and next try unpinning inactive objects.. but that is only useful if you have swap. Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm/mdp5: Add MDSS top level driverArchit Taneja2016-07-161-0/+1
| | | | | | | | | | | | | | | | | | | | SoCs that contain MDP5 have a top level wrapper called MDSS that manages clocks, power and irq for the sub-blocks within it. Currently, the MDSS portions are stuffed into the MDP5 driver. This makes it hard to represent the DT bindings in the correct way. We create a top level MDSS helper that handles these parts. This is essentially moving out some of the mdp5_kms irq code and MDSS register space and keeping it as a separate entity. We haven't given any clocks to the top level MDSS yet, but a AHB clock would be added in the future to access registers. One thing to note is that the resources allocated by this helper are tied to the top level platform_device (the one that allocates the drm_device struct too). This device would be the parent to MDSS sub-blocks like MDP5, DSI, eDP etc. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

* drm/msm/hdmi: HDMI 8996 PHY/PLL supportArchit Taneja2016-02-291-0/+1
| | | | | | | | | | | Add support for the HDMI PHY/PLL found in MSM8996/APQ8096. Unlike the previous PHYs supported in the driver, this doesn't need the powerup/powerdown ops. The PLL prepare/unprepare clock ops enable/disable the phy itself. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm/hdmi: Manage HDMI PLL through PHY driverArchit Taneja2016-02-291-0/+1
| | | | | | | | | | | | | | | | | | | Add a helper to initialize PLL in the PHY driver. HDMI PLLs are going to have their own mmio base different from that of PHY. For the clock code in hdmi_phy_8960.c, some changes were needed for it to work with the updated register offsets. Create a copy of the updated clock code in hdmi_pll_8960.c, instead of rewriting it in hdmi_phy_8960.c itself. This removes the need to place CONFIG_COMMON_CLOCK checks all around, makes the code more legible, and also removes some old checkpatch warnings with the original code. The older hdmi pll clock ops in hdmi_phy_8960.c will be removed later. The driver will use these until the HDMI PHY/PLL register offsets aren't considered as separate domains (i.e. their offsets start from 0).

* drm/msm/hdmi: Create a separate HDMI PHY driverArchit Taneja2016-02-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Create a PHY device that represents the TX PHY and PLL parts of the HDMI block. This makes management of PHY specific resources (regulators and clocks) much easier, and makes the PHY and PLL usable independently. It also simplifies the core HDMI driver, which currently assigns phy ops among many other things. The PHY driver implementation done here is very similar to the PHY driver we already have for DSI. Keep the old hdmi_phy_funcs ops for now. The driver will use these until the HDMI PHY/PLL register offsets aren't considered as separate domains (i.e. their offsets start from 0). The driver doesn't use the common PHY framework for now. This is because it's hard to map our ops with the ops provided by the framework. The bindings used for this is the generic phy bindings. So, this can be adapted to the PHY framework in the future, if possible. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm/dsi: Add DSI PLL for 28nm 8960 PHYArchit Taneja2015-12-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Add DSI PLL common clock framework clocks for 8960 PHY. The PLL here is different from the ones found in B family msm chips. As before, the DSI provides two clocks to the outside world. dsixpll and dsixpllbyte (x = 1, 2). dsixpll is a regular clock divider, but dsixpllbyte is modelled as a custom clock divider. dsixpllbyte is the starting point of the PLL configuration. It is the one that sets up the VCO clock rate. We need the VCO clock rate in the form: F * byteclk, where F is a multiplication factor that varies on the byte clock the DSI driver is trying to set. We use the custom clk_ops for dsixpllbyte to ensure that the parent (VCO) is set at this rate. An additional divider (POSTDIV1) generates the bitclk. Since bit clock can be derived from byteclock, we calculate it internally, and don't expose it as a clock.

| | | | | | | | | | | | DRM_MSM_FBDEV config is used to enable/disable fbdev emulation for the msm kms driver. Replace this with the top level DRM_FBDEV_EMULATION config option where applicable.

* drm/msm/mdp4: add LVDS panel supportRob Clark2014-09-101-0/+3
| | | | | | | | | | | | | | LVDS panel support uses the LCDC (parallel) encoder. Unlike with HDMI, there is not a separate LVDS block, so no need to split things into a bridge+connector. Nor is there is anything re-used with mdp5. Note that there can be some regulators shared between HDMI and LVDS (in particular, on apq8064, ext_3v3p), so we should not use the _exclusive() variants of devm_regulator_get(). The drm_panel framework is used for panel-specific driver. Signed-off-by: Rob Clark <robdclark@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | Add support for the new MDP5 display controller block. The mapping between parts of the display controller and KMS is: plane -> PIPE{RGBn,VIGn} \ crtc -> LM (layer mixer) |-> MDP "device" encoder -> INTF / connector -> HDMI/DSI/eDP/etc --> other device(s) Unlike MDP4, it appears we can get by with a single encoder, rather than needing a different implementation for DTV, DSI, etc. (Ie. the register interface is same, just different bases.) Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are routed through MDP. And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from which blocks need to be allocated to the active pipes based on fetch stride. Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm: add hdmi support for apq8x74/mdp5Rob Clark2014-01-091-0/+1
| | | | | | | | | | | | | | | | The HDMI block is basically the same between older SoC's with mdp4 display controller, and newer ones with mdp5. So mostly this consists of better abstracting out the different sets of regulators, clks, etc. In particular, for regulators and clks we can split it up by what is needed for hot plug detect to work, and what is needed to light up the display. Also, 8x74 has a new phy.. a very simple one, but split out into a different mmio space. And with mdp5, the irq is shared with mdp, so we don't directly register our own irq handler.

* drm/msm: move irq utils to mdp_kmsRob Clark2014-01-091-0/+1

* drm/msm: move mdp4 -> mdp/mdp4Rob Clark2014-01-091-6/+6

* drm/msm: add support for non-IOMMU systemsRob Clark2014-01-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | Add a VRAM carveout that is used for systems which do not have an IOMMU. The VRAM carveout uses CMA. The arch code must setup a CMA pool for the device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not cool). The user can configure the VRAM pool size using msm.vram module param. Technically, the abstraction of IOMMU behind msm_mmu is not strictly needed, but it simplifies the GEM code a bit, and will be useful later when I add support for a2xx devices with GPUMMU, so I decided to keep this part. It appears to be possible to configure the GPU to restrict access to addresses within the VRAM pool, but this is not done yet. So for now the GPU will refuse to load if there is no sort of mmu. Once address based limits are supported and tested to confirm that we aren't giving the GPU access to arbitrary memory, this restriction can be lifted Signed-off-by: Rob Clark <robdclark@gmail.com>

* drm/msm: add a3xx gpu supportRob Clark2013-08-241-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add initial support for a3xx 3d core. So far, with hardware that I've seen to date, we can have: + zero, one, or two z180 2d cores + a3xx or a2xx 3d core, which share a common CP (the firmware for the CP seems to implement some different PM4 packet types but the basics of cmdstream submission are the same) Which means that the eventual complete "class" hierarchy, once support for all past and present hw is in place, becomes: + msm_gpu + adreno_gpu + a3xx_gpu + a2xx_gpu + z180_gpu This commit splits out the parts that will eventually be common between a2xx/a3xx into adreno_gpu, and the parts that are even common to z180 into msm_gpu. Note that there is no cmdstream validation required. All memory access from the GPU is via IOMMU/MMU. So as long as you don't map silly things to the GPU, there isn't much damage that the GPU can do.

* drm/msm: basic KMS driver for snapdragonRob Clark2013-08-241-0/+25
The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>
