Rename struct dma_buf_map to struct iosys_map and corresponding APIs. Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include <linux/dma-buf-map.h> + #include <linux/iosys-map.h> Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map. Since this is not specific to dma-buf anymore, move the documentation to the "Bus-Independent Device Accesses" section. v2: - Squash patches v3: - Fix wrong removal of dma-buf.h from MAINTAINERS - Move documentation from dma-buf.rst to device-io.rst v4: - Change documentation title and level Signed-off-by:

On TGL/RKL the BIOS likes to use some kind of bogus DBUF layout that doesn't match what the spec recommends. With a single active pipe that is not going to be a problem, but with multiple pipes active skl_commit_modeset_enables() goes into an infinite loop since it can't figure out any order in which it can commit the pipes without causing DBUF overlaps between the planes. We'd need some kind of extra DBUF defrag stage in between to make the transition possible. But that is clearly way too complex a solution, so in the name of simplicity let's just sanitize the DBUF state by simply turning off all planes when we detect a pipe encroaching on its neighbours' DBUF slices. We only have to disable the primary planes as all other planes should have already been disabled (if they somehow were enabled) by earlier sanitization steps. And for good measure let's also sanitize in case the DBUF allocations of the pipes already seem to overlap each other.

During readout we cannot assume the planes are actually using the slices they are supposed to use. The BIOS may have misprogrammed things and put the planes onto the wrong dbuf slices. So let's do the readout more carefully to make sure we really know which dbuf slices are actually in use by the pipe at the time. Cc: <stable@vger.kernel.org> # v5.14+ Signed-off-by:

Reintroduce the !join_mbus single pipe cases for adlp+. Due to the mbus relative dbuf offsets in PLANE_BUF_CFG we need to know the actual slices used by the pipe when doing readout, even when mbus joining isn't enabled. Accurate readout will be needed to properly sanitize invalid BIOS dbuf configurations. This will also make it much easier to play around with the !join_mbus configs for testin/workaround purposes.

Following what was done in drm_cache.c, when the stub for remap_io_mapping() was added in commit 67c430bb ("drm/i915: Skip remap_io_mapping() for non-x86 platforms"), it included a log message with pr_err(). However just the warning is already enough and switching to WARN_ONCE() allows us to keep the log message while avoiding log spam. Signed-off-by:

Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.

The various MI_PREDICATE registers have per-engine instances. Today we only utilize the RCS0 instance of each, but that will likely change in the future; switch to parameterized register definitions to make these easier to work with going forward. Of special note is MI_PREDICATE_RESULT_2; we only use it in one place in the driver today in HSW-specific code. It turns out that the bspec (page 94) lists two different offsets for this register on HSW; one is in the standard location shared by all other platforms (base + 0x3bc) and the other is an unusual location (0x2214). We're using the second, non-standard offset in i915 today; that offset doesn't exist on any other platforms (and it's not even 100% clear that it's correct for HSW) so I've renamed the current non-standard definition to HSW_MI_PREDICATE_RESULT_2; the new cross-platform parameterized macro (which is still unused at the moment) uses the standard offset.

Let's use 'struct i915_range' to express sets of b-counter and mux registers in the perf code. This makes the code more similar to how we handle things like multicast register ranges, forcewake tables, shadow tables, etc. and also lets us avoid needing symbolic register name definitions for the various range end points. With this change, many of the OA register definitions are no longer used in the code, so we can drop their #define's for simplicity. v2: Drop 'inline' from reg_in_range_table(). (Jani) v3: Split the first range in gen12_oa_mux_regs[] so that 0xd08 isn't whitelisted.

Make life simpler by always programming DP M2/N2 with a consistent value. This will lets use do state readout+chec unconditionally. I was first going to just set M2/N2=M1/N1 but then it occurred to me that it might interfere with fastboot on account of BIOS likely leaving the registers zeroed. So let's zero out the values instead (except TU where a zero register value actually means '1'). Still not sure that's the best approach but lets go with it for now. Signed-off-by:

Currently we allow DRRS on IVB PCH ports, but we're missing a few programming steps meaning it is guaranteed to not work. And on HSW DRRS is not supported on anything but port A ever as only transcoder EDP has the M2/N2 registers (though I'm not sure if HSW ever has eDP on any other port). Starting from BDW all transcoders have the dynamically reprogrammable M/N registers so DRRS could work on any port. Stop initializing DRRS on ports where it cannot possibly work.

Make things a bit more explicit by splitting intel_cpu_transcoder_set_m_n() into separate variants for M1/N1 vs. M2/N2. Makes the DRRS M/N programming at least more obvious. Note that for the MST and DRRS cases we don't need to call the M2/N2 variant at all since the transcoders that support those do not have the M2/N2 registers. Same could be said for i9xx_crtc_enable() but I want to do a higher level code sharing between that valleyview_crtc_enable() later in which case we do need the M2/N2 variant. This is also why I keep the transcoder_has_m2_n2() in intel_cpu_transcoder_set_m2_n2() so the caller doesn't have necessarily care what the chosen transcoder supports. Signed-off-by:
