[PATCH] powerpc/xive: skip ioremap() of ESB pages for LSI interrupts

by Cédric Le Goater

The PCI INTx interrupts and other LSI interrupts are handled differently under a sPAPR platform. When the interrupt source characteristics are queried, the hypervisor returns an H_INT_ESB flag to inform the OS that it should be using the H_INT_ESB hcall for interrupt management and not loads and stores on the interrupt ESB pages. A default -1 value is returned for the addresses of the ESB pages. The driver ignores this condition today and performs a bogus IO mapping. Recent changes and the DEBUG_VM configuration option make the bug visible with : [ 0.015518] kernel BUG at arch/powerpc/include/asm/book3s/64/pgtable.h:612!

[PATCH v3] virtio_console: allocate inbufs in add_port() only if it is needed

by Laurent Vivier

When we hot unplug a virtserialport and then try to hot plug again, it fails: (qemu) chardev-add socket,id=serial0,path=/tmp/serial0,server,nowait (qemu) device_add virtserialport,bus=virtio-serial0.0,nr=2,\ chardev=serial0,id=serial0,name=serial0 (qemu) device_del serial0 (qemu) device_add virtserialport,bus=virtio-serial0.0,nr=2,\ chardev=serial0,id=serial0,name=serial0 kernel error: virtio-ports vport2p2: Error allocating inbufs qemu error: virtio-serial-bus: Guest failure in adding port 2 for device \ virtio-serial0.0 This happens because buffers for the in_vq are allocated when the port is added but are not released when the port is unplugged. They are only released when virtconsole is removed (see a7a69ec0d8e4) To avoid the problem and to be symmetric, we could allocate all the buffers in init_vqs() as they are released in remove_vqs(), but it sounds like a waste of memory. Rather than that, this patch changes add_port() logic to ignore ENOSPC error in fill_queue(), which means queue has already been filled.

[PATCH 7/8] drm/panfrost: Add the panfrost_gem_mapping concept

by Boris Brezillon

With the introduction of per-FD address space, the same BO can be mapped in different address space if the BO is globally visible (GEM_FLINK) and opened in different context. The current implementation does not take case into account, and attaches the mapping directly to the panfrost_gem_object. Let's create a panfrost_gem_mapping struct and allow multiple mappings per BO. The mappings are refcounted, which helps solve another problem where mappings were teared down (GEM handle closed by userspace) while GPU jobs accessing those BOs were still in-flight. Jobs now keep a reference on the mappings they use. Fixes: a5efb4c9a562 ("drm/panfrost: Restructure the GEM object creation") Fixes: 7282f7645d06 ("drm/panfrost: Implement per FD address spaces") Cc: <stable(a)vger.kernel.org> Signed-off-by: Boris Brezillon <boris.brezillon(a)collabora.com> --- drivers/gpu/drm/panfrost/panfrost_drv.c | 92 +++++++++++- drivers/gpu/drm/panfrost/panfrost_gem.c | 140 +++++++++++++++--- drivers/gpu/drm/panfrost/panfrost_gem.h | 41 ++++- .../gpu/drm/panfrost/panfrost_gem_shrinker.c | 4 +- drivers/gpu/drm/panfrost/panfrost_job.c | 13 +- drivers/gpu/drm/panfrost/panfrost_job.h | 1 + drivers/gpu/drm/panfrost/panfrost_mmu.c | 61 ++++---- drivers/gpu/drm/panfrost/panfrost_mmu.h | 6 +- drivers/gpu/drm/panfrost/panfrost_perfcnt.c | 34 +++-- 9 files changed, 318 insertions(+), 74 deletions(-) diff --git a/drivers/gpu/drm/panfrost/panfrost_drv.c b/drivers/gpu/drm/panfrost/panfrost_drv.c index 751df975534f..b406b5243b40 100644 --- a/drivers/gpu/drm/panfrost/panfrost_drv.c +++ b/drivers/gpu/drm/panfrost/panfrost_drv.c @@ -78,8 +78,10 @@ static int panfrost_ioctl_get_param(struct drm_device *ddev, void *data, struct static int panfrost_ioctl_create_bo(struct drm_device *dev, void *data, struct drm_file *file) { + struct panfrost_file_priv *priv = file->driver_priv;

❌ FAIL: Test report for kernel 5.3.14-a8a1bb9.cki (stable-queue)

by CKI Project

Hello, We ran automated tests on a recent commit from this kernel tree: Kernel repo: git://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git Commit: a8a1bb9b6315 - platform/x86: hp-wmi: Fix ACPI errors caused by passing 0 as input size The results of these automated tests are provided below. Overall result: FAILED (see details below) Merge: OK Compile: OK Tests: FAILED All kernel binaries, config files, and logs are available for download here: https://artifacts.cki-project.org/pipelines/322089 One or more kernel tests failed: x86_64: ❌ LTP ❌ Boot test ❌ Boot test We hope that these logs can help you find the problem quickly.
