[PATCH AUTOSEL 4.19 1/4] pwm: img: Don't modify HW state in .remove() callback

by Sasha Levin

From: Uwe Kleine-König <u.kleine-koenig(a)pengutronix.de> [ Upstream commit c68eb29c8e9067c08175dd0414f6984f236f719d ] A consumer is expected to disable a PWM before calling pwm_put(). And if they didn't there is hopefully a good reason (or the consumer needs fixing). Also if disabling an enabled PWM was the right thing to do, this should better be done in the framework instead of in each low level driver.

Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage.

It looks like we don't have to do anything for setitimer(), but that was just the first one that I happened to look at. Did you check the other instances to see if anything might be going wrong there? If they are all good, then I have no other concerns and we should probably put your fix back into the stable kernels (Greg has just reverted it after my initial mail). I went through all instances other than the ptp related ones, and I'm pretty confident that they are all good now, in each case either your patch fixes a bug or the value is already known to be positive and it doesn't matter. Are you confident that the ptp instances are all good as well? I did stumble over one small detail: if (ts->tv_sec <= KTIME_SEC_MIN) return KTIME_MIN; I think this is not entirely correct for the case of tv_sec==KTIME_SEC_MIN with a nonzero tv_nsec, as we now round down to the full second. Not sure if that's worth changing, as we also round up for any value between KTIME_SEC_MAX*NSEC_PER_SEC and KTIME_MAX, or between KTIME_MIN and KTIME_SEC_MIN*NSEC_PER_SEC. In practice I guess we care very little about the last nanosecond in the corner cases. Arnd

[PATCH v2] drm/nouveau/ga102-: support ttm buffer moves via copy engine

by Ben Skeggs

From: Ben Skeggs <bskeggs(a)redhat.com> We don't currently have any kind of real acceleration on Ampere GPUs, but the TTM memcpy() fallback paths aren't really designed to handle copies between different devices, such as on Optimus systems, and result in a kernel OOPS. A few options were investigated to try and fix this, but didn't work out, and likely would have resulted in a very unpleasant experience for users anyway. This commit adds just enough support for setting up a single channel connected to a copy engine, which the kernel can use to accelerate the buffer copies between devices. Userspace has no access to this incomplete channel support, but it's suitable for TTM's needs. A more complete implementation of host(fifo) for Ampere GPUs is in the works, but the required changes are far too invasive that they would be unsuitable to backport to fix this issue on current kernels. v2: fix GPFIFO length in RAMFC (reported by Karol) Signed-off-by: Ben Skeggs <bskeggs(a)redhat.com> Cc: Lyude Paul <lyude(a)redhat.com> Cc: Karol Herbst <kherbst(a)redhat.com> Cc: <stable(a)vger.kernel.org> # v5.12+ Reviewed-by: Karol Herbst <kherbst(a)redhat.com> Signed-off-by: Karol Herbst <kherbst(a)redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210906005628.11499-1-skeggs… --- drivers/gpu/drm/nouveau/include/nvif/class.h | 2 + .../drm/nouveau/include/nvkm/engine/fifo.h | 1 + drivers/gpu/drm/nouveau/nouveau_bo.c | 1 + drivers/gpu/drm/nouveau/nouveau_chan.c | 6 +- drivers/gpu/drm/nouveau/nouveau_drm.c | 4 + drivers/gpu/drm/nouveau/nv84_fence.c | 2 +- .../gpu/drm/nouveau/nvkm/engine/device/base.c | 3 + .../gpu/drm/nouveau/nvkm/engine/fifo/Kbuild | 1 + .../gpu/drm/nouveau/nvkm/engine/fifo/ga102.c | 308 ++++++++++++++++++ .../gpu/drm/nouveau/nvkm/subdev/top/ga100.c | 7 +- 10 files changed, 329 insertions(+), 6 deletions(-) create mode 100644 drivers/gpu/drm/nouveau/nvkm/engine/fifo/ga102.c diff --git a/drivers/gpu/drm/nouveau/include/nvif/class.h b/drivers/gpu/drm/nouveau/include/nvif/class.h index c68cc957248e..a582c0cb0cb0 100644 --- a/drivers/gpu/drm/nouveau/include/nvif/class.h +++ b/drivers/gpu/drm/nouveau/include/nvif/class.h @@ -71,6 +71,7 @@ #define PASCAL_CHANNEL_GPFIFO_A /* cla06f.h */ 0x0000c06f #define VOLTA_CHANNEL_GPFIFO_A /* clc36f.h */ 0x0000c36f #define TURING_CHANNEL_GPFIFO_A /* clc36f.h */ 0x0000c46f +#define AMPERE_CHANNEL_GPFIFO_B /* clc36f.h */ 0x0000c76f #define NV50_DISP /* cl5070.h */ 0x00005070 #define G82_DISP /* cl5070.h */ 0x00008270 @@ -200,6 +201,7 @@ #define PASCAL_DMA_COPY_B 0x0000c1b5 #define VOLTA_DMA_COPY_A 0x0000c3b5 #define TURING_DMA_COPY_A 0x0000c5b5 +#define AMPERE_DMA_COPY_B 0x0000c7b5 #define FERMI_DECOMPRESS 0x000090b8 diff --git a/drivers/gpu/drm/nouveau/include/nvkm/engine/fifo.h b/drivers/gpu/drm/nouveau/include/nvkm/engine/fifo.h index 54fab7cc36c1..64ee82c7c1be 100644 --- a/drivers/gpu/drm/nouveau/include/nvkm/engine/fifo.h +++ b/drivers/gpu/drm/nouveau/include/nvkm/engine/fifo.h @@ -77,4 +77,5 @@ int gp100_fifo_new(struct nvkm_device *, enum nvkm_subdev_type, int inst, struct int gp10b_fifo_new(struct nvkm_device *, enum nvkm_subdev_type, int inst, struct nvkm_fifo **);

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage. See https://docs.engineering.redhat.com/x/_wEZB for more details.

[PATCH] arm64/sve: Use correct size when reinitialising SVE state

by Mark Brown

When we need a buffer for SVE register state we call sve_alloc() to make sure that one is there. In order to avoid repeated allocations and frees we keep the buffer around unless we change vector length and just memset() it to ensure a clean register state. The function that deals with this takes the task to operate on as an argument, however in the case where we do a memset() we initialise using the SVE state size for the current task rather than the task passed as an argument. This is only an issue in the case where we are setting the register state for a task via ptrace and the task being configured has a different vector length to the task tracing it. In the case where the buffer is larger in the traced process we will leak old state from the traced process to itself, in the case where the buffer is smaller in the traced process we will overflow the buffer and corrupt memory.
