|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | " This is a bit more than I'd like to be pushing at this point in a cycle, but it's a fairly important issue. There's been numerous reports of more recent GP10[2467] boards failing to load, and I've worked with NVIDIA FW engineers and tracked this down to the FW we've been using not properly supporting the boards in question. I've pushed an update to linux-firmware with the new FW version, which unfortunately contains API changes vs the older firmware. This series teaches the ACR subsystem inside nouveau enough to be able to deal with supporting multiple incompatible FW revisions, and adds support to the relevant chipsets for loading the newer FW revision, if it's available."

And this adds the saturating size helpers and does a treewide replacement for the struct_size() usage. Additionally this adds the overflow testing modules to make sure everything works. I'm still working on the treewide replacements for allocators with "simple" multiplied arguments: *alloc(a * b, ...) -> *alloc_array(a, b, ...) and *zalloc(a * b, ...) -> *calloc(a, b, ...) as well as the more complex cases, but that's separable from this portion of the series.

* drm/nouveau/core/object: pass client directly to ioctl handlersBen Skeggs2017-02-171-19/+28
| | | | | | | | | | | nvkm_object::client refers to the client that created the object, which, is currently always the same as the ioctl caller. Upcoming patches introduce the concept of subclients, where a parent is able to access the object trees of its children, making the above no longer true.

* drm/nouveau/core/object: support lookup of specific object typesBen Skeggs2017-02-171-1/+60
| | | | | | | | | | It turns out we have a nice and convenient way of looking up a specific object type already, by using the func pointer as a key. This will be used to remove the separate object trees for each type we need to be able to search for. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau/core: add missing header dependenciesBaoyou Xie2016-10-121-0/+1
| | | | | | | | | | | | | We get 2 warnings when building kernel with W=1: drivers/gpu/drm/nouveau/nvkm/core/firmware.c:34:1: warning: no previous prototype for 'nvkm_firmware_get' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/core/firmware.c:58:1: warning: no previous prototype for 'nvkm_firmware_put' [-Wmissing-prototypes] In fact, both functions are declared in drivers/gpu/drm/nouveau/include/nvkm/core/firmware.h, so this patch adds missing header dependencies.
