2018-05-18drm/etnaviv: switch MMU page tables to writecombine memoryLucas Stach
We are likely to write multiple page entries at once and already ensure proper write buffer flushing before GPU submit, so this improves CPU time usage in the submit path without any downsides. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Philipp Zabel <p.zabel@pengutronix.de>
2018-05-18drm/etnaviv: remove register loggingLucas Stach
I'm not aware of any case where tracing GPU register manipulation at the kernel level would have been useful. It only adds more indirections and adds to the code size. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>
2018-05-18drm/etnaviv: remove cycling through MMU address spaceLucas Stach
This was useful on MMUv1 GPUs, which don't generate proper faults, when the GPU write caches weren't fully understood and not properly handled by the kernel driver. As this has been fixed for quite some time, the cycling though the MMU address space needlessly spreads out the MMU mappings. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
2018-05-18drm/etnaviv: correct timeout calculationRussell King
The old way did clamp the jiffy conversion and thus caused the timeouts to become negative after some time. Also it didn't work with userspace which actually fills the upper 32bits of the 64bit timestamp value. clock_gettime() is 32-bit on 32-bit architectures. Using 64-bit timespec math, like we do in this commit, means that when a wrap occurs, the specified timeout goes into the past and we can't request a timeout in the future. As the Linux implementation of CLOCK_MONOTONIC is reasonable and starts at 0, the first such timer wrap will occur after approx. 68 years of system uptime.

2018-05-18gpu: host1x: Fix compiler errors by converting to dma_addr_tEmil Goode
The compiler is complaining with the following errors: drivers/gpu/host1x/cdma.c:94:48: error: passing argument 3 of ‘dma_alloc_wc’ from incompatible pointer type [-Werror=incompatible-pointer-types] drivers/gpu/host1x/cdma.c:113:48: error: passing argument 3 of ‘dma_alloc_wc’ from incompatible pointer type [-Werror=incompatible-pointer-types] The expected pointer type of the third argument to dma_alloc_wc() is dma_addr_t but phys_addr_t is passed. Change the phys member of struct push_buffer to be dma_addr_t so that we pass the correct type to dma_alloc_wc(). Also check pb->mapped for non-NULL in the destroy function as that is the right way of checking if dma_alloc_wc() was successful.

2018-05-18Merge branch 'linux-4.18' of git://github.com/skeggsb/linux into drm-nextDave Airlie
The main thing here is the addition of support for Volta GV100 GPUs, everything else basically restructuring display / graphics init code to make it possible to fit Volta support in more nicely. There's a bunch of improvements/fixes scattered in there for earlier GPUs too, particularly graphics engine init on all GPUs from Fermi onwards.

2018-05-18drm/nouveau/gr/gf100-: insert some WFIs during gr initBen Skeggs
Inserted wait-for-gr-idle in the places it seems that RM does it, seems to prevent some random mmio timeouts on Quadro GV100. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/clk: Use list_for_each_entry_from_reverseArushi Singhal
It's better to use "list_for_each_entry_from_reverse" for iterating list than "for loop" as it makes the code more clear to read. This patch replace "for loop" with "list_for_each_entry_from_reverse" and "start" variable with "cstate" which helps in refactoring the code and also "cstate" variable is more commonly used in the other functions. changes in v2: "start" variable is removed, before "cstate" variable was removed but "cstate" is more common so preferred "cstate" over "start".

2018-05-18drm/nouveau: fix temp/pwm visibility, skip hwmon when no sensors existIlia Mirkin
A NV34 GPU was seeing temp and pwm entries in hwmon, which would error out when read. These should not have been visible, but also the whole hwmon object should just not have been registered in the first place.

2018-05-18drm/nouveau: fix nouveau_dsm_get_client_id()'s return typeLuc Van Oostenryck
The method struct vga_switcheroo_handler::get_client_id() is defined as returning an 'enum vga_switcheroo_client_id' but the implementation in this driver, nouveau_dsm_get_client_id(), returns an 'int'. Fix this by returning 'enum vga_switcheroo_client_id' in this driver too. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau: fix mode_valid's return typeLuc Van Oostenryck
The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it.
