Now that tracking is wired up for potentially evictable GEM objects, wire up shrinker and the remaining GEM bits for unpinning backing pages of inactive objects. Disabled by default for now, with an 'enable_eviction' module param to enable so that we can get some more testing on the range of generations (and iommu pairings) supported. Signed-off-by:

Rob Clark authored
Shoot down any mmap's *first* before put_pages(). Also add a WARN_ON that the object is locked (to make it clear that this doesn't race with msm_gem_fault()) and remove a redundant WARN_ON (since is_purgable() already covers that case). Fixes: 68209390 ("drm/msm: shrinker support") Signed-off-by:

Objects that are potential for swapping out are (1) willneed (ie. if they are purgable/MADV_WONTNEED we can just free the pages without them having to land in swap), (2) not on an active list, (3) not dma-buf imported or exported, and (4) not vmap'd. This repurposes the purged list for objects that do not have backing pages (either because they have not been pinned for the first time yet, or in a later patch because they have been unpinned/evicted.

Currently nearly everything, other than newly allocated objects which are not yet backed by pages, is pinned and resident in RAM. But it will be nice to have some stats on what is unpinned once that is supported. Signed-off-by:

Rob Clark authored
Currently these always go together, either when we purge MADV_WONTNEED objects or when the object is freed. But for unpin, we want to be able to purge (unmap from iommu) the vma, while keeping the iova range allocated (so we can remap back to the same GPU virtual address when the object is re-pinned. Signed-off-by:

Rob Clark authored
Currently this doesn't matter since we keep the pages pinned until the object is destroyed. But when we start unpinning pages to allow objects to be evicted to swap, it will. Signed-off-by:
-
Rob Clark authored
So we don't have to duplicate the boilerplate for eviction. This also lets us re-use the main scan loop for vmap shrinker. Signed-off-by:

Currently DPU driver scales bandwidth and core clock for sc7180 only, while the rest of chips get static bandwidth votes. Make all chipsets scale bandwidth and clock per composition requirements like sc7180 does. Drop old voting path completely. Tested on RB3 (SDM845) and RB5 (SM8250). Signed-off-by:

Fill clk_inefficiency_factor, bw_inefficiency_factor and min_prefill_lines in hw catalog data for sdm845 and sm8[12]50. Efficiency factors are blindly copied from sc7180 data, while min_prefill_lines is based on downstream display driver. Signed-off-by:

SM8250 platform has a 8-Levels VIG QoS setting. This setting was missed due to bad interaction with b8dab65b ("drm/msm/dpu: Move DPU_SSPP_QOS_8LVL bit to SDM845 and SC7180 masks"), which was applied in parallel. Fixes: d21fc5df ("drm/msm/dpu1: add support for qseed3lite used on sm8250") Signed-off-by:

Phy driver already knows the source PLL id basing on the set usecase and the current PLL id. Stop passing it to the phy_enable call. As a reminder, dsi manager will always use DSI 0 as a clock master in a slave mode, so PLL 0 is always a clocksource for DSI 0 and it is always a clocksource for DSI 1 too unless DSI 1 is used in the standalone mode.

The src_truthtable config is not used for some of phys, which use other means of configuring the master/slave usecases. Inline this function with the goal of removing src_pll_id argument in the next commit. Signed-off-by:

The 7nm, 10nm and 14nm drivers would store interim data used during VCO/PLL rate setting in the global dsi_pll_Nnm structure. Move this data structures to the onstack storage. While we are at it, drop unused/static 'config' data, unused config fields, etc. Signed-off-by:

Drop duplicate fields pdev and id from dsi_pll_Nnm instances. Reuse those fields from the provided msm_dsi_phy. Signed-off-by:
-
Dmitry Baryshkov authored
All PHY drivers would map dsi_pll area. Some PHY drivers would also map dsi_phy area again (a leftover from old PHY/PLL separation). Move all ioremaps to the common dsi_phy driver code and drop individual ioremapped areas from PHY drivers. Signed-off-by:

Replace PLL accessor functions (pll_read/pll_write*) with the DSI PHY accessors, reducing duplication. Signed-off-by:

Drop the struct msm_dsi_pll abstraction, by including vco's clk_hw directly into struct msm_dsi_phy. Signed-off-by:
-
Dmitry Baryshkov authored
Make save_state/restore callbacks accept struct msm_dsi_phy rather than struct msm_dsi_pll. This moves them to struct msm_dsi_phy_ops, allowing us to drop struct msm_dsi_pll_ops. Signed-off-by:

10nm and 7nm already do not use these helpers, as they handle setting slave DSI clocks after enabling VCO. Modify the rest of PHY drivers to remove unnecessary indirection and drop enable_seq/disable_seq PLL callbacks. Signed-off-by:

Instead of setting the variable and then using it just in the one place, determine vco_delay directly at the PLL configuration time. Signed-off-by:
-
Dmitry Baryshkov authored
These drivers do not use vco_delay variable, so drop it from all of them. Signed-off-by:

Morph msm_dsi_pll_save/restore_state() into msm_dsi_phy_save/restore_state(), thus removing last bits of knowledge about msm_dsi_pll from dsi_manager. Signed-off-by:

Use devm_of_clk_add_hw_provider() to register provided clocks. This allows dropping the remove function alltogether. Signed-off-by:

Use devres-enabled version of clock registration functions. This lets us remove dsi_pll destroy callbacks completely. Signed-off-by:

All MSM DSI PHYs provide two clocks: byte and pixel ones. Register/unregister provided clocks from the generic place, removing boilerplate code from all MSM DSI PHY drivers. Signed-off-by:

msm_dsi_pll_set_usecase() function is not used outside of individual DSI PHY drivers, so drop it in favour of calling the the respective set_usecase functions directly. Signed-off-by:

With the current upstream driver the msm_dsi_phy_type enum does not make much sense: all DSI PHYs are probed using the dt bindings, the phy type is not passed between drivers. Use quirks in phy individual PHY drivers to differentiate minor harware differences and drop the enum. Signed-off-by:

Move all PLL-related callbacks into struct msm_dsi_phy_cfg. This limits the amount of data in the struct msm_dsi_pll. Signed-off-by:

The only PLL using multiple enable sequences is the 28nm PLL, which just does the single step in the loop. Push that support back into the PLL code. Signed-off-by:

Each phy version is tightly coupled with the corresponding PLL code, there is no need to keep them separate. Fuse source files together in order to simplify DSI code. Signed-off-by:

DSI PHY init callback would either map dsi_phy_regulator or dsi_phy_lane depending on the PHY type. Replace those callbacks with configuration options governing mapping those regions. Signed-off-by:

Currently the error checking logic in the dp_debug module could pass zero to PTR_ERR and it causes the below kbot warnings: drivers/gpu/drm/msm/dp/dp_debug.c:378 dp_debug_init() warn: passing zero to 'PTR_ERR' drivers/gpu/drm/msm/dp/dp_debug.c:387 dp_debug_init() warn: passing zero to 'PTR_ERR' drivers/gpu/drm/msm/dp/dp_debug.c:396 dp_debug_init() warn: passing zero to 'PTR_ERR' drivers/gpu/drm/msm/dp/dp_debug.c:405 dp_debug_init() warn: passing zero to 'PTR_ERR' Debugfs functions are not supposed to be checked in the normal case so delete this code. Also it silences the above Smatch warnings that we're checking for NULL when these functions only return error pointers. Reported-by:
