2017-03-07drm/nouveau/secboot: add support for SEC LS firmwareAlexandre Courbot
Support running a message queue firmware on SEC. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: support running ACR on SECAlexandre Courbot
Add support for running the ACR binary on the SEC falcon. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: get start address of blob from ACRAlexandre Courbot
The start address used for secure blobs is not unique to the ACR, but rather blob-dependent. Remove the unique member stored in the ACR structure and make the load function return the start address for the current blob instead. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: add shadow blob argumentAlexandre Courbot
ACR firmware from r364 on need a shadow region for the ACR to copy the WPR region into. Add a flag to indicate that a shadow region is required and manage memory allocations accordingly. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon/msgqueue: add SEC2 supportAlexandre Courbot
Add support for running a msgqueue on the SEC2 falcon. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: support for EMEMAlexandre Courbot
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>
2017-03-07drm/nouveau/falcon: fix base address of FBIF registersAlexandre Courbot
All falcons have their FBIF registers starting at offset 0x600, with the exception of the PMU and NVENC engines. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: better detection of debug registerAlexandre Courbot
Not all falcons have a debug register, and it is not always found at the same offset. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/core: add SEC2 engineAlexandre Courbot
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. Add this engine and make TOP use it all post-TOP devices should use this implementation and not the older SEC. Also quickly add the short gp102 implementation which will be used for falcon booting purposes. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/nvdec: add gp102 supportAlexandre Courbot
gp10x' secure boot requires a blob to be run on NVDEC. Expose the falcon through a dummy device. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: delay construction of falcons to oneinit()Alexandre Courbot
Reading registers at device construction time can be harmful, as there is no guarantee the underlying engine will be up, or in its runtime configuration. Defer register reading to the oneinit() hook and update users accordingly. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: use NXTCTX register instead of NEW_INSTBLKAlexandre Courbot
Both registers allow to bind a new context, but NXTCTX will work on all falcons, while legacy NEW_INSTBLK is reserved to PMU. After setting NXTCTX we trigger a context switch by writing 0x090 and 0x0a4. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot/gm20b: enable PMU firmwareAlexandre Courbot
Enable the PMU firmware in gm20b, managed by secure boot. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/pmu/gm20b: add msgqueue supportAlexandre Courbot
gm20b PMU firmware is driven by a msgqueue, so connect relevant PMU hooks to their msgqueue counterparts. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: check that WPR region is properly setAlexandre Courbot
The ACR firmware may return no error but fail nonetheless. Such cases can be detected by verifying that the WPR region has been properly set in FB. If this is not the case, this is an error, but the unload firmware should still not be run. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: support optional falconsAlexandre Courbot
PMU support has been enabled for r352 ACR, but it must remain optional if we want to preserve existing user-space that do not include it. Allow ACR to be instanciated with a list of optional LS falcons, that will not produce a fatal error if their firmware is not loaded. Also change the secure boot bootstrap logic to be able to fall back to legacy behavior if it turns out the boot falcon's LS firmware cannot be loaded. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: support PMU LS firmwareAlexandre Courbot
Add the PMU bootloader generator and PMU LS ops that will enable proper PMU operation if the PMU falcon is designated as managed. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: base support for PMU falconAlexandre Courbot
Adapt secboot's behavior if a PMU firmware is present, in particular the way LS falcons are reset. Without PMU firmware, secboot needs to be performed again from scratch so all LS falcons are reset. With PMU firmware, we can ask the PMU's ACR unit to reset a specific falcon through a PMU message. As we must preserve the old behavior to avoid breaking user-space, add a few conditionals to the way falcons are reset. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: support for loading LS PMU firmwareAlexandre Courbot
Allow secboot to load a LS PMU firmware. LS PMU is one instance of firmwares based on the message queue mechanism, which is also used for other firmwares like SEC, so name its source file accordingly. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/pmu: add msgqueue memberAlexandre Courbot
NVIDIA-provided PMU firmware is controlled by a msgqueue. Add a member to the PMU structure as well as the required cleanup code if this feature is used. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: support for gm20b msgqueueAlexandre Courbot
Add support for the msgqueue firmware used to process PMU commands for gm20b. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: add msgqueue interfaceAlexandre Courbot
A message queue firmware implements a specific protocol allowing the host to send "commands" to a falcon, and the falcon to reply using "messages". This patch implements the common part of this protocol and defines the interface that the host can use. Due to the way the firmware is developped internally at NVIDIA (where kernel driver and firmware evolve in lockstep), firmwares taken at different points in time can have frustratingly subtle differences that must be taken into account. This code is architectured to make implementing such differences as easy as possible. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: add LS firmware post-run hooksAlexandre Courbot
Add the ability for LS firmwares to declare a post-run hook that is invoked right after the HS firmware is executed. This allows them to e.g. write some initialization data into the falcon's DMEM. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: abstract fixup_hs_desc functionAlexandre Courbot
As different firmare versions use different HS descriptor formats, we need to abstract this part as well. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: make specialized ls_ucode_img struct privateAlexandre Courbot

2017-03-07drm/nouveau/secboot: store ucode offset in base image structureAlexandre Courbot
This allows the bootloader descriptor generation code to not rely on specialized ls_ucode_img structures, making it reusable in other instances. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: fix usage of hsf_load_headerAlexandre Courbot
Offsets were not properly computed. This went unnoticed because we are only using one app for now. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: prevent address trimmingAlexandre Courbot

2017-03-07drm/nouveau/secboot: fix WPR region alignmentAlexandre Courbot
A WPR region smaller than 256K will result in secure boot failure. Adjust the minimal size. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: fix WPR address to be 64-bitAlexandre Courbot
The WPR address parameter of the ls_write_wpr hook was defined as a u32, which will very likely overflow on boards with more than 4GB VRAM. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-03-07drm/nouveau/falcon: protect against concurrent DMEM accessesAlexandre Courbot
The falcon library may be used concurrently, especially after the introduction of the msgqueue interface. Make it safe to use it that way. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/falcon: add missing context binding memory targetAlexandre Courbot
This is not used currently, but is added for the sake of completeness. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/pmu: make sure the reset hook exists before running itAlexandre Courbot
Some PMU implementations (in particular the ones managed by secure boot) may not have a reset() hook. Make sure we don't crash in that case. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/secboot: make nvkm_secboot_falcon_name visibleAlexandre Courbot
Make nvkm_secboot_falcon_name publicly visible as other subdevs will need to use it for debug messages. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-03-07drm/nouveau/priv: punt messages to debug levelBen Skeggs
Ideally we'd be able to keep these at a more obvious error level, as they're a good indication of us doing something wrong. However, NVIDIA's FECS/GPCCS firmware touches registers that trigger priv ring faults, and we can't do anything to fix that ourselves due to the need for them to be signed by NVIDIA. This issue was reported a while back, but hasn't been fixed, so, for now we will hide the messages to prevent spamming Optimus users with messages whenever the NVIDIA GPU is powered off and on again.

2017-02-26drm/vmwgfx: Work around drm removal of control nodesThomas Hellstrom
vmware tools has a daemon that gets layout information from the GUI and forwards it to DRM so that the modesetting code can set preferred connector locations and modes. This daemon was using control nodes but since control nodes were just removed, make it possible for the daemon to use render- or primary nodes instead. This is a bit ugly but will allow drm to proceed with removal of the mostly unused control-node code and allow vmware to proceed with fixing up automatic layout settings for gnome-shell/wayland. We bump minor to inform user-space about the api change.
