This fixes audio endpoints disappearing due to missing unsolicited notifications. [How] Send the notification via the audio component whenever we enable or disable audio state on a stream. This matches what i915 does with their drm_audio_component and what Takashi Iwai's proposed hack for radeon/amdpgu did. This is a bit delayed in when the notification actually occurs, however. We wait until after all the programming is complete rather than sending the notification mid sequence. Particular care is needed for the get ELD callback since it can happen outside the locking and fencing DRM does for atomic commits.

I.e. in komeda_plane_atomic_check() first try komeda_build_layer_data_flow() and if that fails, try komeda_build_layer_split_data_flow(), and set dflow.en_split accordingly. Assuming I understand somewhat correctly what this does. - If this is needed for validation then you want a debugfs file to force this one way or the other, or alternatively use ->atomic_print_state to dump such hidden driver-private state.

Furthermore driver-private kms properties are highly discouraged, over the past few years we've realized we need to make a serious effort at better standardizing this stuff.

Instead of exposing a komeda-specific limitation to userspace and expecting them to dtrt. I think msm and rcar-du do that already (and others), if you need people to chat with or example code. - If this is needed for validation, again ->atomic_print_state and the infrastructure around that is your friend.

Furthermore driver-private kms properties are highly discouraged, over the past few years we've realized we need to make a serious effort at better standardizing this stuff. From the discussion with Liviu the solution for these here needs multiple pieces: - For being able to reliably read the memory clock we need a DT property, plus maybe DT override snippets to fix it if it's wrong. - For exposing plane limitations to userspace there's TEST_ONLY. There is a bit a gap in telling userspace better that scaling doesn't work due to limits (atm a good strategy is to retry again without scaling when adding a plane didn't work the first time around). But that needs a more generic solution, not exposing something extremely komeda specific. - If this is needed by validation tools, you can still expose it in debugfs. We have an entire nice infrastructure for debug printing of kms objects already, see the various atomic_print_state callbacks and infrastructure around them.

These days it's completely pointless - dentries of pipes are not even connected to pipefs root. However, mount_pseudo() had set the root dentry name (passed as the second argument) and callers kept inventing names to pass to it. Including those that didn't *have* any non-root dentries to start with... All of that had been pointless for about 8 years now; it's time to get rid of that cargo-culting...

This function uses the extra1 and extra2 members from struct ctl_table as minimum and maximum allowed value. On sysctl handler declaration, in every source file there are some readonly variables containing just an integer which address is assigned to the extra1 and extra2 members, so the sysctl range is enforced. The special values 0, 1 and INT_MAX are very often used as range boundary, leading duplication of variables like zero=0, one=1, int_max=INT_MAX in different source files: $ git grep -E '\.extra[12].*&(zero|one|int_max)' |wc -l 248 Add a const int array containing the most commonly used values, some macros to refer more easily to the correct array member, and use them instead of creating a local one for every object file.

The cdrom.txt and hdio.txt have their own particular syntax. In order to speedup the conversion, I used a small ancillary perl script: my $d; $d .= $_ while(<>); $d =~ s/(\nCDROM\S+)\s+(\w[^\n]*)/$1\n\t$2\n/g; $d =~ s/(\nHDIO\S+)\s+(\w[^\n]*)/$1\n\t$2\n/g; $d =~ s/(\n\s*usage:)[\s\n]*(\w[^\n]*)/$1:\n\n\t $2\n/g; $d =~ s/(\n\s*)(E\w+[\s\n]*\w[^\n]*)/$1- $2/g; $d =~ s/(\n\s*)(inputs|outputs|notes):\s*(\w[^\n]*)/$1$2:\n\t\t$3\n/g; print $d; It basically add blank lines on a few interesting places. The script is not perfect: still several things require manual work, but it saved quite some time doing some obvious stuff.

This reduces necessary write memory bandwidth by at least 25% (more with rotation enabled).

To fully characterize a colorspace conversion, the Y'CbCr encoding standard, and quantization also need to be specified. Define a 'struct ipu_ic_colorspace' that includes all the above. This allows to actually enforce the fact that the IC: - can only encode to/from YUV and RGB full range. A follow-up patch will remove this restriction. - can only encode using BT.601 standard. A follow-up patch will add Rec.709 encoding support. The determination of the CSC coefficients based on the input/output 'struct ipu_ic_colorspace' are moved to a new exported function ipu_ic_calc_csc(), and 'struct ic_csc_params' is exported as 'struct ipu_ic_csc_params'. ipu_ic_calc_csc() fills a 'struct ipu_ic_csc' with the input/output 'struct ipu_ic_colorspace' and the calculated 'struct ic_csc_params' from those input/output colorspaces. The functions ipu_ic_task_init(_rsc)() now take a filled 'struct ipu_ic_csc'. The existing CSC coefficient tables and ipu_ic_calc_csc() are moved to a new module ipu-ic-csc.c. This is in preparation for adding more coefficient tables for limited range quantization and more encoding standards. The existing ycbcr2rgb and inverse rgb2ycbcr tables defined the BT.601 Y'CbCr encoding coefficients. The rgb2ycbcr table specifically described the BT.601 encoding from full range RGB to full range YUV. Table comments have been added in ipu-ic-csc.c to make this more clear. The ycbcr2rgb inverse table described encoding YUV limited range to RGB full range. To be consistent with the rgb2ycbcr table, this table is converted to YUV full range to RGB full range, and the comments are expanded in ipu-ic-csc.c. The ic_csc_rgb2rgb table was just an identity matrix, so it is renamed 'identity' in ipu-ic-csc.c.

| | * | | | drm/amdgpu: don't invalidate caches in RELEASE_MEM, only do the writebackMarek Olšák2019-07-091-5/+1

Invalidations only make sense with the Acquire semantic (ACQUIRE_MEM), or when RELEASE_MEM is used to do the combined Acquire-Release semantic, which is a barrier, not a fence. The undesirable side effect of doing invalidations for the Release semantic is that it invalidates caches while shaders are running, because the Release can execute in the middle of the next IB. UMDs should use ACQUIRE_MEM at the beginning of IBs. Doing cache invalidations for a fence (like in this case) doesn't do anything for correctness.
