2013-09-04drm/nouveau: use MSI interruptsLucas Stach
MSIs were only problematic on some old, broken chipsets. But now that we already see systems where PCI legacy interrupts are somewhat flaky, it's really time to move to MSIs. v2 (Ben Skeggs): blacklist BR02 boards Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-09-04drm/nouveau/core: get rid of math.h, replace log2i with order_base_2Ilia Mirkin

2013-04-26drm/nouveau/mc: handle irq-related setup ourselvesBen Skeggs
We need to be able to process interrupts before the DRM code is able to actually enable them, set it up ourselves. Also, it's less convoluted to *not* use the DRM wrappers it appears... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-02-20drm/nouveau/therm: implement support for temperature alarmsMartin Peres
For now, we only boost the fan speed to the maximum and auto-mode when hitting the FAN_BOOST threshold and halt the computer when it reaches the shutdown temperature. The downclock and critical thresholds do nothing. On nv43:50 and nva3+, temperature is polled because of the limited hardware. I'll improve the nva3+ situation by implementing alarm management in PDAEMON whenever I can but polling once every second shouldn't be such a problem. v2 (Ben Skeggs): - rebased v3: fixed false-detections and threshold reprogrammation handling on nv50:nvc0 Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>
2012-10-03drm/nouveau/mxm: split up into bios code and a subdev moduleBen Skeggs

2012-10-03drm/nouveau/gpio: port gpio to subdev interfacesBen Skeggs
v2: Ben Skeggs <bskeggs@redhat.com> - rebase on top of v3.6-rc6 with gpio reset patch integrated already Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/bios: pull in basic vbios subdev, more to come laterBen Skeggs
v2: Ben Skeggs <bskeggs@redhat.com> - use unaligned macros to access vbios image - endianness fixes Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/core: pull in most of the new core infrastructureBen Skeggs
This commit provides most of the infrastructure to support a major overhaul of Nouveau's internals coming in the following commits. This work aims to take all the things we've learned over the last several years, and turn that into a cleaner architecture that's more maintainable going forward. RAMHT and MM bits of the new core have been left out for the moment, and will be pulled in as I go through the process of porting the code to become either subdev or engine modules. There are several main goals I wanted to achieve through this work: -- Reduce complexity The goal here was to make each component of the driver as independent as possible, which will ease maintainability and readability, and provide a good base for resetting locked up GPU units in the future. -- Better tracking of GPU units that are required at any given time This is for future PM work, we'll be able to tell exactly what parts of the GPU we need powered at any given point (etc). -- Expose all available NVIDIA GPUs to the client In order to support things such as multi-GPU channels, we want to be able to expose all the NVIDIA GPUs to the client over a single file descriptor so it can send a single push buffer to multiple GPUs. -- Untangle the core hardware support code from the DRM implementation This happened initially as an unexpected side-effect of developing the initial core infrastructure in userspace, but it turned into a goal of the whole project. Initial benefits will be the availablility of a number of userspace tools and tests using the same code as the driver itself, but will also be important as I look into some virtualisation ideas. v2: Ben Skeggs <bskeggs@redhat.com> - fix duplicate assignments noticed by clang - implement some forgotten yelling in error path - ensure 64-bit engine mask is used everywhere v3: Marcin Slusarz <marcin.slusarz@gmail.com> - sparse fixes - inline nv_printk into nv_assert to prevent recursive inlining issues v4: Ben Skeggs <bskeggs@redhat.com> - fixed minor memory leak on gpuobj destruction Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
