[Nouveau] [PATCH v3 00/15] Secure Boot refactoring
This is a rework of the secure boot code that moves the building of the blob into its own set of source files (and own hooks), making the code more flexible and (hopefully) easier to understand as well. This rework is needed to support more signed firmware for existing and new chips. Since the firmwares in question are not available yet I cannot send the code to manage then, but hopefully the gain in clarity will be enough to merge this series ahead of the rest. Of the whole series, patch 8 is the most significant as it reorganizes the code into more source files. Chip support is separated from the ACR implementation, with ACR being numbered according to the (public) NVIDIA driver version it was build aainst. This means one can make any chip work with any ACR version just by instanciating the proper ACR and adds a lot of flexibility that will be required as more firmwares get released. At the moment, released firmwares cover driver versions 352 (for GM20B) and 361 (for GM200, GM204, GM206 and GP100). The r361 implementation re-uses most of r352, and only implements its own BL descritors since the structure changed between the two versions. Other patches are a mix of minor optimizations (1, 2, 3, 4, 9, 10, 12, 13, 15), small fixes (5, 7, 11), and addition of abstractions to properly support various ACR versions (6, 14). Not all the abstractions are used at the moment (particularly those of patch 14), but hopefully they will be put to good use soon! Changes since v1: - Use NVIDIA driver versions to differenciate the ACR structures instead of arbitrary numbers - Add abstractions to firmware loading functions - Optimized set of abstractions - Removed some more code Changes since v2: - Fix naming of new structures/functions Alexandre Courbot (15): core: constify nv*_printk macros core: add falcon library secboot: use falcon library's IMEM/DMEM loading functions secboot: rename init() hook to oneinit() secboot: remove fixup_hs_desc hook secboot: add low-secure firmware hooks secboot: generate HS BL descriptor in hook secboot: reorganize into more files secboot: add LS flags to LS func structure secboot: split reset function secboot: disable falcon interrupts before running secboot: remove unneeded ls_ucode_img member secboot: remove ls_ucode_mgr secboot: abstract LS firmware loading functions secboot: safer zeroing of BL descriptors drm/nouveau/include/nvkm/core/client.h | 4 +- drm/nouveau/include/nvkm/core/device.h | 2 +- drm/nouveau/include/nvkm/core/falcon.h | 50 + drm/nouveau/include/nvkm/core/subdev.h | 2 +- drm/nouveau/include/nvkm/subdev/secboot.h | 32 +- drm/nouveau/nvkm/core/Kbuild | 1 + drm/nouveau/nvkm/core/falcon.c | 62 ++ drm/nouveau/nvkm/engine/gr/gf100.c | 16 +- drm/nouveau/nvkm/engine/gr/gm200.c | 6 +- drm/nouveau/nvkm/subdev/secboot/Kbuild | 4 + drm/nouveau/nvkm/subdev/secboot/acr.c | 54 + drm/nouveau/nvkm/subdev/secboot/acr.h | 68 ++ drm/nouveau/nvkm/subdev/secboot/acr_r352.c | 925 +++++++++++++++++ drm/nouveau/nvkm/subdev/secboot/acr_r352.h | 246 +++++ drm/nouveau/nvkm/subdev/secboot/acr_r361.c | 135 +++ drm/nouveau/nvkm/subdev/secboot/base.c | 118 ++- drm/nouveau/nvkm/subdev/secboot/gm200.c | 1335 +------------------------ drm/nouveau/nvkm/subdev/secboot/gm200.h | 43 + drm/nouveau/nvkm/subdev/secboot/gm20b.c | 127 +-- drm/nouveau/nvkm/subdev/secboot/ls_ucode.h | 151 +++ drm/nouveau/nvkm/subdev/secboot/ls_ucode_gr.c | 158 +++ drm/nouveau/nvkm/subdev/secboot/priv.h | 199 +--- 22 files changed, 2091 insertions(+), 1647 deletions(-) create mode 100644 drm/nouveau/include/nvkm/core/falcon.h create mode 100644 drm/nouveau/nvkm/core/falcon.c create mode 100644 drm/nouveau/nvkm/subdev/secboot/acr.c create mode 100644 drm/nouveau/nvkm/subdev/secboot/acr.h create mode 100644 drm/nouveau/nvkm/subdev/secboot/acr_r352.c create mode 100644 drm/nouveau/nvkm/subdev/secboot/acr_r352.h create mode 100644 drm/nouveau/nvkm/subdev/secboot/acr_r361.c create mode 100644 drm/nouveau/nvkm/subdev/secboot/gm200.h create mode 100644 drm/nouveau/nvkm/subdev/secboot/ls_ucode.h create mode 100644 drm/nouveau/nvkm/subdev/secboot/ls_ucode_gr.c -- 2.10.0

[Nouveau] [PATCH v3 02/15] core: add falcon library
Some falcon functionality, like loading code/data into IMEM/DMEM, is
re-implemented in various parts of the driver. Create a small falcon
library that will contain most common operations in order to avoid
duplicate code.
For now this library contains various defines that are used in secure
boot code, plus IMEM and DMEM loading functions.
In addition to the library itself, this patch updates users of the
previously secure-boot only definitions to use the new global ones.

[Nouveau] [PATCH v3 06/15] secboot: add low-secure firmware hooks
Secure firmwares provided by NVIDIA will follow the same overall
principle, but may slightly differ in format, or not use the same
bootloader descriptor even on the same chip. In order to handle
this as gracefully as possible, turn the LS firmware functions into
hooks that can be overloaded as needed.
The current hooks cover the external firmware loading as well as the
bootloader descriptor generation.

[Nouveau] [PATCH v3 07/15] secboot: generate HS BL descriptor in hook
Use the HS hook to completely generate the HS BL descriptor, similarly
to what is done in the LS hook, instead of (arbitrarily) using the
acr_v1 format as an intermediate.
This allows us to make the bootloader descriptor structures private to
each implementation, resulting in a cleaner an more consistent design.

[Nouveau] [PATCH v3 14/15] secboot: abstract LS firmware loading functions
The WPR and LSB headers, used to generate the LS blob, may have a
different layout and sizes depending on the driver version they come
from. Abstract them and confine their use to driver-specific code.

Perform the zeroing of BL descriptors in the caller function instead of
trusting each generator will do it. This could avoid a few pulled hairs.

[Nouveau] [PATCH v3 08/15] secboot: reorganize into more files
Split the act of building the ACR blob from firmware files from the rest
of the (chip-dependent) secure boot logic. ACR logic is moved into
acr_rxxx.c files, where rxxx corresponds to the compatible release of
the NVIDIA driver. At the moment r352 and r361 are supported since
firmwares have been released for these versions. Some abstractions are
added on top of r352 so r361 can easily be implemented on top of it by
just overriding a few hooks.
This split makes it possible and easy to reuse the same ACR version on
different chips. It also hopefully makes the code much more readable as
the different secure boot logics are separated. As more chips and
firmware versions will be supported, this is a necessity to not get lost
in code that is already quite complex.
This is a big commit, but it essentially moves things around (and split
the nvkm_secboot structure into two, nvkm_secboot and nvkm_acr). Code
semantics should not be affected.

+ * Secure boot is the process by which NVIDIA-signed firmware is loaded into
+ * some of the falcons of a GPU. For production devices this is the only way
+ * for the firmware to access useful (but sensitive) registers.
+ *
+ * A Falcon microprocessor supporting advanced security modes can run in one of
+ * three modes:
+ *
+ * - Non-secure (NS). In this mode, functionality is similar to Falcon
+ * architectures before security modes were introduced (pre-Maxwell), but
+ * capability is restricted. In particular, certain registers may be
+ * inaccessible for reads and/or writes, and physical memory access may be
+ * disabled (on certain Falcon instances). This is the only possible mode
that
+ * can be used if you don't have microcode cryptographically signed by
NVIDIA.
+ *
+ * - Heavy Secure (HS). In this mode, the microprocessor is a black box -
it's
+ * not possible to read or write any Falcon internal state or Falcon
registers
+ * from outside the Falcon (for example, from the host system). The only way
+ * to enable this mode is by loading microcode that has been signed by
NVIDIA.
+ * (The loading process involves tagging the IMEM block as secure, writing
the
+ * signature into a Falcon register, and starting execution. The hardware
will
+ * validate the signature, and if valid, grant HS privileges.)
+ *
+ * - Light Secure (LS). In this mode, the microprocessor has more privileges
+ * than NS but fewer than HS. Some of the microprocessor state is visible to
+ * host software to ease debugging. The only way to enable this mode is by HS
+ * microcode enabling LS mode. Some privileges available to HS mode are not
+ * available here. LS mode is introduced in GM20x.
+ *
+ * Secure boot consists in temporarily switching a HS-capable falcon (typically
+ * PMU) into HS mode in order to validate the LS firmwares of managed falcons,
+ * load them, and switch managed falcons into LS mode. Once secure boot
+ * completes, no falcon remains in HS mode.
+ *
+ * Secure boot requires a write-protected memory region (WPR) which can only be
+ * written by the secure falcon. On dGPU, the driver sets up the WPR region in
+ * video memory. On Tegra, it is set up by the bootloader and its location and
+ * size written into memory controller registers.
+ *
+ * The secure boot process takes place as follows:
+ *
+ * 1) A LS blob is constructed that contains all the LS firmwares we want to
+ * load, along with their signatures and bootloaders.
+ *
+ * 2) A HS blob (also called ACR) is created that contains the signed HS
+ * firmware in charge of loading the LS firmwares into their respective
+ * falcons.
+ *
+ * 3) The HS blob is loaded (via its own bootloader) and executed on the
+ * HS-capable falcon. It authenticates itself, switches the secure falcon to
+ * HS mode and setup the WPR region around the LS blob (dGPU) or copies the
+ * LS blob into the WPR region (Tegra).
+ *
+ * 4) The LS blob is now secure from all external tampering. The HS falcon
+ * checks the signatures of the LS firmwares and, if valid, switches the
+ * managed falcons to LS mode and makes them ready to run the LS firmware.
+ *
+ * 5) The managed falcons remain in LS mode and can be started.

-/*
- * Secure boot is the process by which NVIDIA-signed firmware is loaded into
- * some of the falcons of a GPU. For production devices this is the only way
- * for the firmware to access useful (but sensitive) registers.
- *
- * A Falcon microprocessor supporting advanced security modes can run in one of
- * three modes:
- *
- * - Non-secure (NS). In this mode, functionality is similar to Falcon
- * architectures before security modes were introduced (pre-Maxwell), but
- * capability is restricted. In particular, certain registers may be
- * inaccessible for reads and/or writes, and physical memory access may be
- * disabled (on certain Falcon instances). This is the only possible mode
that
- * can be used if you don't have microcode cryptographically signed by
NVIDIA.
- *
- * - Heavy Secure (HS). In this mode, the microprocessor is a black box -
it's
- * not possible to read or write any Falcon internal state or Falcon
registers
- * from outside the Falcon (for example, from the host system). The only way
- * to enable this mode is by loading microcode that has been signed by
NVIDIA.
- * (The loading process involves tagging the IMEM block as secure, writing
the
- * signature into a Falcon register, and starting execution. The hardware
will
- * validate the signature, and if valid, grant HS privileges.)
- *
- * - Light Secure (LS). In this mode, the microprocessor has more privileges
- * than NS but fewer than HS. Some of the microprocessor state is visible to
- * host software to ease debugging. The only way to enable this mode is by HS
- * microcode enabling LS mode. Some privileges available to HS mode are not
- * available here. LS mode is introduced in GM20x.
- *
- * Secure boot consists in temporarily switching a HS-capable falcon (typically
- * PMU) into HS mode in order to validate the LS firmwares of managed falcons,
- * load them, and switch managed falcons into LS mode. Once secure boot
- * completes, no falcon remains in HS mode.
- *
- * Secure boot requires a write-protected memory region (WPR) which can only be
- * written by the secure falcon. On dGPU, the driver sets up the WPR region in
- * video memory. On Tegra, it is set up by the bootloader and its location and
- * size written into memory controller registers.
- *
- * The secure boot process takes place as follows:
- *
- * 1) A LS blob is constructed that contains all the LS firmwares we want to
- * load, along with their signatures and bootloaders.
- *
- * 2) A HS blob (also called ACR) is created that contains the signed HS
- * firmware in charge of loading the LS firmwares into their respective
- * falcons.
- *
- * 3) The HS blob is loaded (via its own bootloader) and executed on the
- * HS-capable falcon. It authenticates itself, switches the secure falcon to
- * HS mode and setup the WPR region around the LS blob (dGPU) or copies the
- * LS blob into the WPR region (Tegra).
- *
- * 4) The LS blob is now secure from all external tampering. The HS falcon
- * checks the signatures of the LS firmwares and, if valid, switches the
- * managed falcons to LS mode and makes them ready to run the LS firmware.
- *
- * 5) The managed falcons remain in LS mode and can be started.
