Add intel_de_read64_2x32() wrapper for the uncore version of the same, and use it to read the high and low frame registers. Avoid duplicating code for existing helpers. The slight functional difference is checking that the entire high register remains the same across two reads, instead of just the part we're interested in. This should be of no consequence.

Using DEFINE_SIMPLE_ATTRIBUTE macro with the debugfs_create_file() function adds the overhead of introducing a proxy file operation functions to wrap the original read/write inside file removal protection functions. This adds significant overhead in terms of introducing and managing the proxy factory file operations structure and function wrapping at runtime. As a replacement, a combination of DEFINE_DEBUGFS_ATTRIBUTE macro paired with debugfs_create_file_unsafe() is suggested to be used instead. The DEFINE_DEBUGFS_ATTRIBUTE utilises debugfs_file_get() and debugfs_file_put() wrappers to protect the original read and write function calls for the debug attributes. There is no need for any runtime proxy file operations to be managed by the debugfs core. Following coccicheck make command helped identify this change: make coccicheck M=drivers/gpu/drm/i915/ MODE=patch COCCI=./scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci Signed-off-by:

Add all the know DSB instruction opcodes. Signed-off-by:

Ville Syrjälä authored
The caller should more or less know how many DSB commands it wants to emit into the command buffer, so allow it to specify the size of the command buffer rather than having the low level DSB code guess it. Technically we can emit as many as 134+1033 (for adl+ degamma + 10bit gamma) register writes but thanks to the DSB indexed register write command we get significant space savings so the current size estimate of 8KiB (~1024 DSB commands) is sufficient for now.

Move the DSB tail cacheline alignment to a helper. No need to pollute the caller with mundane details like this. Signed-off-by:
-
Ville Syrjälä authored
The DSB indexed register write insturction is purely an internal DSB implementation detail, no reason why the caller should have to know about it. So let's just have the caller emit blind register writes let the DSB code convert things to an indexed write if/when multiple writes occur to the same register offset in a row. Signed-off-by:
-
Ville Syrjälä authored
Currently intel_dsb_indexed_reg_write() just assumes the previous instructions is also an indexed register write, and thus only checks the register offset. Make the check more robust by actually checking the instruction opcode as well. Signed-off-by:

free_pos is in dwords, DSB_BUF_SIZE in bytes. Directly comparing the two is nonsense. Fix it up, and make sure we also account for the 8byte alignment requirement for each instruction, and also assume that each instruction normally eats two dwords. Signed-off-by:
-
Ville Syrjälä authored
Every DSB instruction has to be 8byte aligned. Make sure that is the case for the non-indexed register writes as well. The way this could end up unaligned is we emitted an odd number of indexed register writes beforehand. Signed-off-by:

In newer hardware versions (i.e. display version >= 14), the second scaler doesn't support vertical scaling. The current implementation of the scaling limits is simplified and only occurs when the planes are created, so we don't know which scaler is being used. In order to handle separate scaling limits for horizontal and vertical scaling, and different limits per scaler, split the checks in two phases. We first do a simple check during plane creation and use the best-case scenario (because we don't know the scaler that may be used at a later point) and then do a more specific check when the scalers are actually being set up.

There are new cases where we want to block i915 probe, such as when experimenting or developing the new Xe driver. But also, with the new hybrid cards, users or developers might want to use i915 only on integrated and fully block the probe of the i915 for the discrete. Or vice versa. There are even older development and validation reasons, like when you use some distro where the modprobe.blacklist is not present. But in any case, let's introduce a more granular control, but without introducing yet another parameter, but using the existent force_probe one. Just by adding a ! in the begin of the id in the force_probe, like in this case where we would block the probe for Alder Lake: $ insmod i915.ko force_probe='!46a6' v2: Take care of '*' and '!*' cases as pointed out by Gustavo and Jani.

The busy timeout logic checks for the AUX BUSY, then waits for the timeout period and then after timeout reads the register for BUSY or Success. Instead replace interrupt with polling so as to read the AUX CTL register often before the timeout period. Looks like there might be some issue with interrupt-on-read. Hence changing the logic to polling read. v2: replace interrupt with polling read v3: use usleep_rang instead of msleep, updated commit msg v4: use intel_wait_for_regiter internal function v5: use __intel_de_wait_for_register with 500us slow and 10ms fast timeout v6: check return value of __intel_de_wait_for_register v7: using default 2us for intel_de_wait_for_register Signed-off-by:
