| | | | | | | | | | | | | | | | | | | | MMU will be needing this to specify kind info on BAR mappings. We have no userspace currently using these interfaces, so break the ABI instead of supporting both. NVIF version bump so any future use can be guarded. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-02132-0/+132
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm/nouveau/disp: Silence DCB warnings.Rosen Penev2017-08-222-0/+2
| | | | | | | | | | | | | Most of these errors seem to be WFD related. Official documentation says dcb type 8 is reserved. It's probably used for WFD. Silence the warning in either case. Connector type 70 is stated to be a virtual connector for WiFi display. Since we know this, don't warn that we don't.

* drm/nouveau/disp/nv50-: implement a common supervisor 3.0Ben Skeggs2017-06-161-5/+1
| | | | | | | | This makes use of all the additional routing and state added in previous commits, making it possible to deal with GM20x macro link routing, while also sharing code between the NV50 and GF119 implementations. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/disp: introduce acquire/release display path methodsBen Skeggs2017-06-161-0/+9
| | | | | | | | | | | | | | | | | | These exist to give NVKM information on the set of display paths that the DD needs to be active at any given time. Previously, the supervisor attempted to determine this solely from OR state, but there's a few configurations where this information on its own isn't enough to determine the specific display paths in question: - ANX9805, where the PIOR protocol for both DP and TMDS is TMDS. - On a device using DCB Switched Outputs. - On GM20x and newer, with a crossbar between the SOR and macro links. After this commit, the DD tells NVKM *exactly* which display path it's attempting a modeset on. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau/disp: introduce input/output resource abstractionBen Skeggs2017-06-161-0/+1
| | | | | | | | | | In order to properly support the SOR -> SOR + pad macro separation that occurred with GM20x GPUs, we need to separate OR handling out of the output path code. This will be used as the base to support ORs (DAC, SOR, PIOR). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | The nouveau driver, in the Linux 3.7 days, used to try and set the AVI InfoFrame based on the selected display mode. These days, it uses a fixed set of InfoFrames. Start to correct that, by providing a mechanism whereby InfoFrame data may be passed to the NVKM functions that do the actual configuration. At this point, only establish the new parameters and their parsing, don't actually use the data anywhere yet (since it's not supplied anywhere).

* drm/nouveau/tmr: fully separate alarm execution/pending listsBen Skeggs2017-06-061-0/+1
| | | | | | | | | | | | Reusing the list_head for both is a bad idea. Callback execution is done with the lock dropped so that alarms can be rescheduled from the callback, which means that with some unfortunate timing, lists can get corrupted. The execution list should not require its own locking, the single function that uses it can only be called from a single context.

* drm/nouveau/secboot: pass instance to LS firmware loadersAlexandre Courbot2017-04-061-6/+3
| | | | | | | | | | | | Having access to the secboot instance loading a LS firmware can be useful to LS firmware handlers. At least more useful than just having an out-of-context subdev pointer. GP10B's firmware will also need to know the WPR address, which can be obtained from the secboot instance.

* drm/nouveau/secboot: allow to boot multiple falconsAlexandre Courbot2017-04-062-3/+2
| | | | | | | | | | | | Change the secboot and msgqueue interfaces to take a mask of falcons to reset instead of a single falcon. The GP10B firmware interface requires FECS and GPCCS to be booted in a single firmware command. For firmwares that only support single falcon boot, it is trivial to loop over the mask and boot each falcons individually.

* drm/nouveau/fb/gf100-: rework ram detectionBen Skeggs2017-03-071-0/+6
| | | | | | | | | | | | | | | | This commit reworks the RAM detection algorithm, using RAM-per-LTC to determine whether a board has a mixed-memory configuration instead of using RAM-per-FBPA. I'm not certain the algorithm is perfect, but it should handle all currently known configurations in the very least. This should fix GTX 970 boards with 4GiB of RAM where the last 512MiB isn't fully accessible, as well as only detecting half the VRAM on GF108 boards. As a nice side-effect, GP10x memory detection now reuses the majority of the code from earlier chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | On some secure boot instances (e.g. gp10x) the load and unload blobs do not run on the same falcon. Support this case by introducing a new member to the ACR structure and making related functions take the falcon to use as an argument instead of assuming the boot falcon is to be used. The rule is that the load blob can be run on either the SEC or PMU falcons, but the unload blob must be always run on PMU.

* drm/nouveau/falcon: support for EMEMAlexandre Courbot2017-03-071-0/+1
| | | | | | | | | | | | | On SEC, DMEM is unaccessible by the CPU when the falcon is running in LS mode. This makes communication with the firmware using DMEM impossible. For this purpose, a new kind of memory (EMEM) has been added. It works similarly to DMEM, with the difference that its address space starts at 0x1000000. For this reason, it makes sense to treat it like a special case of DMEM. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | SEC2 is the name given by NVIDIA to the SEC engine post-Fermi (reasons unknown). Even though it shares the same address range as SEC, its usage is quite different and this justifies a new engine.
