2020-01-15drm/nouveau/secboot: removeBen Skeggs1-102/+0
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/secboot: move code to boot LS falcons to subdevsBen Skeggs1-74/+1
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/flcn/msgq: move handling of init message to subdevsBen Skeggs1-2/+0
When the PMU/SEC2 LS FWs have booted, they'll send a message to the host with various information, including the configuration of message/command queues that are available. Move the handling for this to the relevant subdevs. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/sec2: initialise SW state for falcon from constructorBen Skeggs1-2/+2
This will allow us to register the falcon with ACR, and further customise its behaviour by providing the nvkm_falcon_func structure directly. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-01-15drm/nouveau/pmu: initialise SW state for falcon from constructorBen Skeggs1-3/+3
This will allow us to register the falcon with ACR, and further customise its behaviour by providing the nvkm_falcon_func structure directly. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2019-07-19drm/nouveau/secboot/gp102-: remove WAR for SEC2 RTOS start bugBen Skeggs1-29/+0
Appears to be fixed by "flcn/gp102-: improve implementation of bind_context() on SEC2/GSP". Tested on GP10[24678] and GV100. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2019-06-07drm/nouveau/secboot: enable loading of versioned LS PMU/SEC2 ACR msgqueue FWBen Skeggs1-14/+14
Some chipsets will be switching to updated SEC2 LS firmware, so we need to plumb that through. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2019-06-07drm/nouveau/secboot: pass max supported FW version to LS load funcsBen Skeggs1-5/+7
Will be passed to the FW loader function as an upper bound on the supported FW version to attempt to load. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2019-06-07drm/nouveau/core: pass subdev into nvkm_firmware_get, rather than deviceBen Skeggs1-3/+3
It'd be nice to have FW loading debug messages to appear for the relevant subsystem, when enabled. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/secboot: remove VLA usageGustavo A. R. Silva1-4/+3
In preparation to enabling -Wvla, remove VLA. In this particular case directly use macro NVKM_MSGQUEUE_CMDLINE_SIZE instead of local variable cmdline_size. Also, remove cmdline_size as it is not actually useful anymore. The use of stack Variable Length Arrays needs to be avoided, as they can be a vector for stack exhaustion, which can be both a runtime bug or a security flaw. Also, in general, as code evolves it is easy to lose track of how big a VLA can get. Thus, we can end up having runtime failures that are hard to debug. Also, fixed as part of the directive to remove all VLAs from the kernel: https://lkml.org/lkml/2018/3/7/621 Signed-off-by: Gustavo A. R.

2017-11-02drm/nouveau/secboot: add missing newline in debug messageBen Skeggs1-1/+1

2017-04-06drm/nouveau/secboot: start LS firmware in post-run hookAlexandre Courbot1-2/+47
The LS firmware post-run hook is the right place to start said LS firmware. Moving it here also allows to remove special handling in the ACR code. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/secboot: let LS post_run hooks return errorAlexandre Courbot1-5/+18
A LS post-run hook can meet an error meaning the failure of secure boot. Make sure this can be reported. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-04-06drm/nouveau/secboot: pass instance to LS firmware loadersAlexandre Courbot1-10/+8
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.

2017-03-07drm/nouveau/secboot: add support for SEC LS firmwareAlexandre Courbot1-0/+32
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 for loading LS PMU firmwareAlexandre Courbot1-0/+117
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.
