2018-02-20drm/msm: add sudo flag to submit ioctlRob Clark4-0/+88
This flags cause cmdstream to be executed from the ringbuffer (RB) instead of IB1. Normally not something you'd ever want to do, but it is super useful for firmware debugging. Hidden behind CAP_SYS_RAWIO and a default=n kconfig option which depends on EXPERT (and has a suitably scary warning), to prevent it from being used on accident.

2018-02-20drm/msm: add a5xx specific debugfsRob Clark7-1/+207
Add some debugfs to dump out PFP and ME microcontroller state, as well as some of the queues (MEQ and ROQ). Also add a debugfs file to trigger a GPU reset (and reloading the firmware on next submit). Signed-off-by: Rob Clark <robdclark@gmail.com>

2018-02-20drm/msm/dsi: check for failure on retrieving pll in dsi managerLloyd Atkinson3-4/+8
Make msm_dsi_pll_init consistently return an error code instead of NULL when pll initialization fails so that later pll retrieval can check against an error code. Add checks for these failures after retrieval of src_pll to avoid invalid pointer dereferences later in msm_dsi_pll_get_clk_provider.

2018-01-23drm/msm/mdp5: Use drm_mode_get_hv_timing() to populate plane clip rectangleVille Syrjälä1-10/+10
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. Note that this replaces crtc_state->adjusted_mode usage with crtc_state->mode. The latter is the correct choice since that's the mode the user provided and it matches the plane crtc coordinates the user also provided. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state().

The msm/kms driver should work even if there is no GPU device specified in DT. Currently, we get a NULL dereference crash in adreno_load_gpu since the driver assumes that priv->gpu_pdev is non-NULL. Perform an additional check on priv->gpu_pdev before trying to retrieve the msm_gpu pointer from it. v2: Incorporate Jordan's comments: - Simplify the check to share the same error message. - Use dev_err_once() to avoid an error message every time we open the drm device fd.

2017-12-28clk: divider: fix incorrect usage of container_ofJerome Brunet1-1/+1
divider_recalc_rate() is an helper function used by clock divider of different types, so the structure containing the 'hw' pointer is not always a 'struct clk_divider' At the following line: > div = _get_div(table, val, flags, divider->width); in several cases, the value of 'divider->width' is garbage as the actual structure behind this memory is not a 'struct clk_divider' Fortunately, this width value is used by _get_val() only when CLK_DIVIDER_MAX_AT_ZERO flag is set. This has never been the case so far when the structure is not a 'struct clk_divider'.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook2-8/+6
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2017-10-28drm/msm/mdp5: Don't use async plane update path if plane visibility changesArchit Taneja1-0/+25
When a plane moves out of bounds (i.e, outside the crtc clip region), the plane state's "visible" parameter changes to false. When this happens, we (a) release the hwpipe resources away from it, and (b) unstage the corresponding hwpipe(s) from the Layer Mixers in the CRTC. (a) requires use to acquire the global atomic state and assign a new hwpipe. (b) requires us to re-configure the Layer Mixer, which is done in the CRTC. We don't want to do these things in the async plane update path, so return an error if the new state's "visible" isn't the same as the current state's "visible".

Do not try to restore the MDP5 LM cursor registers, or the corresponding CTL bits if we are not using LM cursors. Also, since we've introduced a new variable 'lm_cursor_enabled', we can now use it to avoid creating a different sets of crtc_funcs for CRTCs with LM cursors and CRTCs with cursor planes.

2017-10-28drm/msm/mdp5: Update mdp5_pipe_assign to spit out both planesArchit Taneja3-20/+57
We currently call mdp5_pipe_assign() twice to assign the left and right hwpipes for our drm_plane. When merging 2 hwpipes, there are a few constraints that we need to keep in mind: - Only the same types of SSPPs are preferred. I.e, a RGB pipe should be paired with another RGB pipe, VIG with VIG etc. - The hwpipe staged on the left should have a higher priority than the hwpipe staged on the right. The priorities are as follows: VIG0 > VIG1 > VIG2 > VIG3 RGB0 > RGB1 > RGB2 > RGB3 DMA0 > DMA1 We can't apply these constraints easily if mdp5_pipe_assign() is called twice.

This can result in situations where we think the cursor is enabled when we enable the CRTC but it is trying to scan out null (and the rest of cursor position/size is lost), resulting in faults and generally angering the hw when coming out of DPMS with a cursor enabled. stable backport note: reverting 774e39ee3572 is also a suitable fix Fixes: 774e39ee3572 drm/msm/mdp5: Set up runtime PM for MDSS Signed-off-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Archit Taneja <architt@codeaurora.org>

It's only likely to paper over bugs. Unlike the gpu, where we want to keep things alive a bit longer in expectation of the next frame's submit, when the display is shut down we can power off immediately. Signed-off-by: Rob Clark <robdclark@gmail.com> Acked-by: Archit Taneja <architt@codeaurora.org>

Note we need to move update_fences() to after msm_rd_dump_submit(), otherwise the bo's referenced by the submit may no longer be valid. Signed-off-by: Rob Clark <robdclark@gmail.com>
