* gpu: nvgpu: Cast unsigned arith to signed for abs()Alex Waterman2018-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | Before passing in an unsigned value to abs() cast the result of the subtraction to signed. In Linux this happens automatically but on non-Linux platforms abs() does not necessarily do this. clang flags this case as a pointless operation: abs(x) obviously must equal x for any unsigned x. This change should hopefully preserve the Linux behavior but avoid the compiler warning from clang.

* gpu: nvgpu: remove broken force_pramin featureKonsta Holtta2018-05-24
| | | | | | | | | | | | | | The forced PRAMIN reads and writes for sysmem buffers haven't worked in a while since the PRAMIN access code was refactored to work with vidmem-only sgt allocs. This feature was only ever meant for testing and debugging PRAMIN access and early dGPU support, but that is stable enough now so just delete the broken feature instead of fixing it.

* gpu: nvgpu: handle clk arb event posting in OS specific codeSourab Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mechanism of posting events to userspace is OS specific. In linux this works through poll fd, wherein we can make use of nvgpu_cond variables to poll and trigger the corresponding wait_queue. The post event functionality on QNX doesn't work on poll though. It uses iofunc_notify_trigger to post the events to the calling process. As such QNX can't work with nvgpu_cond's. To overcome this issue, it is proposed to create OS specific interface function for posting clk arb events. Linux can call nvgpu_cond based implementation, which makes sense since these are already initialized and poll'ed in Linux specific code only. QNX can implement this interface to call iofunc_notify_* functions, as per its need.

| | | | | | | | | | | | | | | | | | | This header doesn't have anything in it yet but the header is now present. A change recently went in that only checked for __KERNEL__ before falling back to including the QNX header. This caused the POSIX build in GVS to attempt to include the QNX header. The QNX src is not synced in userspace dev-kernel tests builds resulting in a missing header.

| | | | | | | | | | | | | | | | | | | | | | | | | Currently gpu sysfs retrieves Fmax@Vmin by direct call into Tegra DVFS driver that introduces compile time dependencies on CONFIG_TEGRA_DVFS. In addition incorrect clock is used for DVFS information access. Re-factored sysfs node to use generic GPU clock operation for Fmax@Vmin read. This would fix a bug in target clock selection, and allows to remove dependency of sysfs on CONFIG_TEGRA_DVFS. Updated nvgpu_linux_get_fmax_at_vmin_safe operation itself so it can be called on platforms that does not support Tegra DVFS, although 0 will still be returned as Fmax@Vmin on such platforms.

* gpu: nvgpu: poll watchdog status activelyKonsta Holtta2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read GP_GET and GET from hardware every time when the poll timer expires instead of when the watchdog timer expires. Restart the watchdog timer if the get pointers have increased since the previous read. This way stuck channels are detected quicker. Previously it could have taken at most twice the watchdog timeout limit for a stuck channel to get recovered; with this change, a coarse sliding window is used. The polling period is still 100 ms. The difference is illustrated in the following diagram: time 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 get a b b b b b b b b b b b b b b b b b b b b prev - n n n n n n n n n A n n n n n n n n n S next - A s s s s s s s s s S "time" represents wall time in polling units; 0 is submit time. For simplicity, watchdog timeout is ten units. "get" is the GP_GET that advances a little from a and then gets stuck at b. "prev" is the previous behaviour, "next" is after this patch. "A" is when the channel is detected as advanced, and "S" when it's found stuck and recovered; small "s" is when it's found stuck but when the time limit has not yet expired and "n" is when the hw state is not read.
