Registration of the hwmon device will fail on non-PCI systems since dev->pdev is NULL in that case. Use the more generic drm_device::dev member that points to the same and is always set no matter the platform. Signed-off-by:

The DMA API has different semantics on different architectures. Currently on arm64, it can only provide memory from a small pool which dries up quickly if we attempt to allocate big buffers from it. Do not consider that option when running on non-x86, since regular TTM buffers are the (current) best-fit for ARM platforms. Signed-off-by:

LTC operations timeout was set to 2ms, which may be too low for devices that run at very low clocks (e.g. GM20B) and trigger timeout messages. Set the timeout to the default 2s. Also remove the redundant error messages since nvkm_wait_msec() will already display a warning. Signed-off-by:

Bits 28:29 of RUNLIST_BASE specify the memory target of the runlist. Set it to 0x3 (SYS_MEM_NONCOHERENT) if the runlist object resides in system memory. Signed-off-by:

Fix the channel id bit mask in FIFO schedule timeout error handling. FIFO_ENGINE_STATUS_NEXT_ID is bit 27:16 thus 0x0fff0000. FIFO_ENGINE_STATUS_ID is bit 11:0 thus 0x00000fff. Signed-off-by:

DMA mask is typically set in nouveau_ttm_init(), but this function is called late during initialization and GK20A's instmem will have called DMA functions before this happens. Having a wrongly set DMA mask can result in the use of unneeded bounce buffers. Set it early to avoid this. Signed-off-by:

Add secure boot support for the GM20B chip found in Tegra X1. Secure boot on Tegra works slightly differently from desktop, notably in the way the WPR region is set up. In addition, the firmware bootloaders use a slightly different header format. Signed-off-by:

Start securely-managed falcons using secboot functions since the process for them is different from just writing CPUCTL. Signed-off-by:
-
Alexandre Courbot authored
On GM200 and later GPUs, firmware for some essential falcons (notably GR ones) must be authenticated by a NVIDIA-produced signature and loaded by a high-secure falcon in order to be able to access privileged registers, in a process known as Secure Boot. Secure Boot requires building a binary blob containing the firmwares and signatures of the falcons to be loaded. This blob is then given to a high-secure falcon running a signed loader firmware that copies the blob into a write-protected region, checks that the signatures are valid, and finally loads the verified firmware into the managed falcons and switches them to privileged mode. This patch adds infrastructure code to support this process on chips that require it. v2: - The IRQ mask of the PMU falcon was left - replace it with the proper irq_mask variable. - The falcon reset procedure expecting a falcon in an initialized state, which was accidentally provided by the PMU subdev. Make sure that secboot can manage the falcon on its own. Signed-off-by:

The firmwares required by GR may vary from chip to chip, especially with the introduction of secure boot and NVIDIA-provided firmwares. Move the firmware loading outside of gf100_gr_ctor so other chips may still call it while managing their firmwares themselves. Signed-off-by:

Some members of gf100_gr were freed by the gk20a driver. That's not where it should be done - free them in gf100 so other chips that use NVIDIA-provided firmware free these structures properly. This also removes the need for a GK20A-specific destructor. Signed-off-by:

Most of the per-chipset differences will go away when we fully switch to using the register lists provided by the firmware files, which will leave all the remaining code "belonging" to GM200. This is a preemptive rename from GM204 to GM200. Signed-off-by: -

It is not advisable to perform devinit if it has already been done. VBIOS will very likely have invoked devinit if the GPU is the primary graphics device, but there is no accurate way to detect this fact yet. This patch adds such a method for gf100 and later chips, by means of the NV_PTOP_SCRATCH1_DEVINIT_COMPLETED bit. This bit is set to 1 by devinit, and reset to 0 when the GPU is powered.

nvkm_device_tegra_new initializes the irq member of the Tegra device to -1 in order to signal that it is uninitialized. However, nvkm_device_tegra_fini tests it against 0 to check whether an IRQ has been allocated or not. This leads to free_irq being called on -1 during device initialization. Fix this by using 0 as the uninitialized value everywhere. Signed-off-by:
