The function dpu_plane_sspp_update_pipe() contains code to skip enabling the QoS and OT limitis for CURSOR pipes. However all DPU since sdm845 repurpose DMA SSPP for the cursor planes because they lack the real CURSOR SSPP. Fix the condition to actually check that the plane is CURSOR or not. Reviewed-by:

Get rid of intermediatory configuration structure and defines. Pass the format and the enablement bit directly to the new helper. The WB_CDP_CNTL register ignores BIT(2), so we can write it for both SSPP and WB CDP settings. Reviewed-by:

Move the check for lm->pingpong being not NONE from dpu_rm_init() to dpu_lm_init(), following the change to dpu_hw_intf_init(). Suggested-by:

On msm8998/sdm845 some LM blocks do not have corresponding PINGPONG block. Currently the driver uses PINGPONG_MAX for such cases. Switch that to use PINGPONG_NONE instead, which is more logical. Reviewed-by:

dpu_rm_init() contains checks for block->id values. These were logical in the vendor driver, when one can not be sure which values were passed from DT. In the upstream driver this is not necessary: the catalog is a part of the driver, we control specified IDs. Suggested-by:

Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If the value is NULL, then the function will return 0 instead of a proper return code. Moreover dpu_hw_dsc_init() can not return NULL. Replace the IS_ERR_OR_NULL() call with IS_ERR(). This follows the commit 740828c7 ("drm/msm/dpu: fix error handling in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but then the commit f2803ee9 ("drm/msm/disp/dpu1: Add DSC support in RM") added it for DSC init.

Stop using _sspp_subblk_offset() to get offset of the csc_blk. Inline this function and use ctx->cap->sblk->csc_blk.base directly. As this was the last user, drop _sspp_subblk_offset() too. Reviewed-by:

The src_blk declares a lame copy of main SSPP register space. It's offset is always 0. It's length has been fixed to 0x150, while SSPP's length is now correct. Drop the src_blk and access SSPP registers without additional subblock lookup. Signed-off-by:

Since DPU 5.0.0 the TEARCHECK registers and interrupts moved out of the PINGPONG block and into the INTF. Implement the necessary callbacks in the INTF block, and use these callbacks together with the INTF_TEAR interrupts. Signed-off-by:
-
Marijn Suijten authored
These functions are always called consecutively and are best bundled together for simplicity, especially when the same structure of callbacks will be replicated later on the interface block for INTF TE support. The enable_tearcheck(false) case is now replaced with a more obvious disable_tearcheck(), encapsulating the original register write with 0. Suggested-by:

All SoCs since DPU 5.0.0 have the tear interrupt registers moved out of the PINGPONG block and into the INTF block. The new interrupts are described in dpu_hw_interrupts.c, now wire them up in individual SoC catalog files by setting the intr_tear_rd_ptr to the IRQ index spcified in the offset table and enabling this set of DPU interrupts via the mdss_irqs bitmask.

As the INTF block is going to attain more interrupts that don't share the same MDP_SSPP_TOP0_INTR register, factor out the _reg argument for the caller to construct the right interrupt index (register and bit index) to not make the interrupt bit arguments depend on one of multiple interrupt register indices. This brings us more in line with how PP_BLK specifies its interrupts and allows for better wrapping in the arrays. Signed-off-by:

Since hardware revision 5.0.0 the TE configuration moved out of the PINGPONG block into the INTF block, including vsync source selection that was previously part of MDP top. Writing to the MDP_VSYNC_SEL register has no effect anymore and is omitted downstream via the DPU/SDE_MDP_VSYNC_SEL feature flag. This flag is only added to INTF blocks used by hardware prior to 5.0.0. The code that writes to these registers in the INTF block will follow in subsequent patches. Signed-off-by:

Since hardware revision 5.0.0 the TE configuration moved out of the PINGPONG block into the INTF block. Writing these registers has no effect, and is omitted downstream via the DPU/SDE_PINGPONG_TE feature flag. This flag is only added to PINGPONG blocks used by hardware prior to 5.0.0. The existing PP_BLK_TE macro has been removed in favour of directly passing this feature flag, which has thus far been the only difference with PP_BLK. PP_BLK_DITHER has been left in place as its embedded feature flag already excludes this DPU_PINGPONG_TE bit and differs by setting the block length to zero, as it only contains a DITHER subblock. The code that writes to these registers in the INTF block will follow in subsequent patches. Signed-off-by:

This autorefresh disable logic in the physical command-mode encoder consumes three callbacks to the pingpong block, and will explode in unnecessary complexity when the same callbacks need to be called on the interface block instead to accommodate INTF TE support. To clean this up, move the logic into the pingpong block under a disable_autorefresh callback, replacing the aforementioned three get_autorefresh, setup_autorefresh and get_vsync_info callbacks. The same logic will have to be replicated to the interface block when it receives INTF TE support, but it is less complex than constantly switching on a "has_intf_te" boolean to choose a callback.

Instead of hardcoding many register defines for every INTF and AD4 index with a fixed stride, turn the defines into singular chunks of math that compute the address using the base and this fixed stride multiplied by the index given as argument to the definitions. MDP_SSPP_TOP0_OFF is dropped as that constant is zero anyway, and all register offsets related to it live in dpu_hwio.h. Suggested-by:

According to various downstream sources the PCC sub-block inside DSPP is version 4.0 since DPU 4.0 and higher, including SC7[12]80 at DPU version 6.2 and 7.2 respectively. After correcting the version this struct becomes identical to sm8150_dspp_sblk which is used all across the catalog: replace uses of sc7180_dspp_sblk with that and remove the struct definition for sc7180_dspp_sblk entirely.

The Resource Manager already iterates over all available blocks from the catalog, only to pass their ID to a dpu_hw_xxx_init() function which uses an _xxx_offset() helper to search for and find the exact same catalog pointer again to initialize the block with, fallible error handling and all. Instead, pass const pointers to the catalog entries directly to these _init functions and drop the for loops entirely, saving on both readability complexity and unnecessary cycles at boot.

Do not override the hsync/vsync polarity passed by the encoder when setting up intf timings. The same logic was used in both the encoder and intf code to set the DP and DSI polarities, so those interfaces are not impacted. However for HDMI, the polarities were overriden to static values based on the vertical resolution, instead of using the actual mode polarities. Signed-off-by:
