The function dpu_encoder_get_wb() returns controller_id if the corresponding WB is present in the catalog. We can inline this function and rely on dpu_rm_get_wb() returning NULL for indices for which the WB is not present on the device. Reviewed-by:

Currently DSC flushing happens during interface configuration at dpu_hw_ctl_intf_cfg_v1(). Separate DSC flush away from dpu_hw_ctl_intf_cfg_v1() by adding dpu_hw_ctl_update_pending_flush_dsc_v1() to handle both per-DSC engine and DSC flush bits at same time to make it consistent with the location of flush programming of other DPU sub-blocks.

There are two tiers of pending flush control, top level and individual hardware block. Currently only the top level of flush mask is reset to 0 but the individual pending flush masks of particular hardware blocks are left at their previous values, eventually accumulating all possible bit values and typically flushing more than necessary. Reset all individual hardware block flush masks to 0 to avoid accidentally flushing them.

Disabling the crossbar mux between DSC and PINGPONG currently requires a bogus enum dpu_pingpong value to be passed when calling dsc_bind_pingpong_blk() with enable=false, even though the register value written is independent of the current PINGPONG block. Replace that `bool enable` parameter with a new PINGPONG_NONE dpu_pingpong flag that triggers the write of the "special" 0xF "crossbar disabled" value to the register instead.

DPU < 7.0.0 has DPU_PINGPONG_DSC feature bit set to indicate it requires both dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() to be executed to complete DSC configuration if DSC hardware block is present. Hence test DPU_PINGPONG_DSC feature bit and assign DSC related functions to the ops of PINGPONG block accordingly if DPU_PINGPONG_DSC bit is set. Changes in v6: -- split patches, this patch has function handles DPU_PINGPONG_DSC bit Changes in v9: -- the original code of assigning dsc related functions to the ops of pingpong block without testing the DPU_PINGPONG_DSC feature bit was restored back due to rebase error which defeat the purpose of this patch. Remove those error code. Changes in v10: -- change commit title -- correct texts at changes in v9 Changes in v12: -- fixed length too long at Changes in v9 Signed-off-by: -

DPU < 7.0.0 requires the PINGPONG block to be involved during DSC setting up. Since DPU >= 7.0.0, enabling and starting the DSC encoder engine was moved to INTF with the help of the flush mechanism. Add a DPU_PINGPONG_DSC feature bit to restrict the availability of dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() on the PINGPONG block to DPU < 7.0.0 hardware, as the registers are not available on DPU 7.0.0 and higher anymore. Add DPU_PINGPONG_DSC to PINGPONG_SDM845_MASK, PINGPONG_SDM845_TE2_MASK and PINGPONG_SM8150_MASK which is used for all DPU < 7.0 chipsets. changes in v6: -- split patches and rearrange to keep catalog related files at this patch changes in v7: -- rewording commit text as suggested at review comments changes in v9: -- delete BIT(DPU_PINGPONG_DSC) from PINGPONG_SDM845_TE2_MASK changes in v10: -- correct order of commit text Signed-off-by: -

The CTL_FLUSH register should be programmed with the 22th bit (DSC_IDX) to flush the DSC hardware blocks, not the literal value of 22 (which corresponds to flushing VIG1, VIG2 and RGB1 instead).

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:

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.

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.
