2026-04-03drm/amdgpu: Use amdgpu by default for CIK APUs tooTimur Kristóf1-2/+1
CIK APUs are: Kaveri, Kabini and Mullins from 2013~2015, which all have a second generation GCN based integrated GPU. The amdgpu driver has been working well on CIK APUs for years. Features which were previously missing have been added recently, specifically DC support for analog connectors and DP bridge encoders. Now amdgpu is at feature parity with the old radeon driver on CIK APUs. Enabling the amdgpu driver by default for CIK APUs has the following benefits: - More stable OpenGL support through RadeonSI - Vulkan support through RADV - Improved performance - Better display features through DC Users who want to keep using the old driver can do so using: amdgpu.cik_support=0 radeon.cik_support=1 Signed-off-by: Timur Kristóf <timur.kristof@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2026-04-03drm/radeon: add WQ_PERCPU to alloc_workqueue usersMarco Crivellari1-1/+2
This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The refactoring is going to alter the default behavior of alloc_workqueue() to be unbound by default. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. For more details see the Link tag below. In order to keep alloc_workqueue() behavior identical, explicitly request WQ_PERCPU.

2026-03-13ACPI: AC: Define ACPI_AC_CLASS in one placeRafael J. Wysocki1-2/+0
The ACPI_AC_CLASS symbol is defined in several places in the same way which is rather unfortunate. Instead, define it in one common header file (acpi_bus.h) so that it is accessible to all of its users. No intentional functional impact. Signed-off-by: Rafael J.

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds12-50/+25
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds34-67/+67
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook34-159/+158
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull MSI updates from Thomas Gleixner: "Updates for the [PCI] MSI subsystem: - Add interrupt redirection infrastructure Some PCI controllers use a single demultiplexing interrupt for the MSI interrupts of subordinate devices. This prevents setting the interrupt affinity of device interrupts, which causes device interrupts to be delivered to a single CPU. That obviously is counterproductive for multi-queue devices and interrupt balancing. To work around this limitation the new infrastructure installs a dummy irq_set_affinity() callback which captures the affinity mask and picks a redirection target CPU out of the mask. When the PCI controller demultiplexes the interrupts it invokes a new handling function in the core, which either runs the interrupt handler in the context of the target CPU or delegates it to irq_work on the target CPU. - Utilize the interrupt redirection mechanism in the PCI DWC host controller driver. This allows affinity control for the subordinate device MSI interrupts instead of being randomly executed on the CPU which runs the demultiplex handler. - Replace the binary 64-bit MSI flag with a DMA mask Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but implement less than 64 address bits. This breaks on platforms where such a device is assigned an MSI address higher than what's supported. With the binary 64-bit flag there is no other choice than disabling 64-bit MSI support which leaves the device disfunctional. By using a DMA mask the address limit of a device can be described correctly which provides support for the above scenario. - Make use of the DMA mask based address limit in the hda/intel and radeon drivers to enable them on affected platforms - The usual small cleanups and improvements" * tag 'irq-msi-2026-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: ALSA: hda/intel: Make MSI address limit based on the device DMA limit drm/radeon: Make MSI address limit based on the device DMA limit PCI/MSI: Check the device specific address mask in msi_verify_entries() PCI/MSI: Convert the boolean no_64bit_msi flag to a DMA address mask genirq/redirect: Prevent writing MSI message on affinity change PCI/MSI: Unmap MSI-X region on error genirq: Update effective affinity for redirected interrupts PCI: dwc: Enable MSI affinity support PCI: dwc: Code cleanup genirq: Add interrupt redirection infrastructure genirq/msi: Correct kernel-doc in <linux/msi.h>
2026-01-31drm/radeon: Make MSI address limit based on the device DMA limitVivian Wang2-10/+1
The radeon driver restricts the MSI message address for devices older than the BONAIR generation to 32-bit MSI addresses due to the former restrictions of the PCI/MSI code which only allowed either 32-bit or full 64-bit address range. This does not work on platforms which have a MSI doorbell address above the 32-bit boundary but do not support the full 64 bit address range. The PCI/MSI core converted this binary decision to a DMA_BIT_MASK() based decision, which allows to describe the device limitations precisely. Convert the driver to provide the exact DMA address limitations to the PCI/MSI core. That allows devices which do not support the full 64-bit address space to work on platforms which have a MSI doorbell address above the 32-bit limit as long as it is within the hardware's addressable range.

2026-01-31PCI/MSI: Convert the boolean no_64bit_msi flag to a DMA address maskVivian Wang1-1/+1
Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but implement less than 64 address bits. This breaks on platforms where such a device is assigned an MSI address higher than what's supported. Currently, no_64bit_msi bit is set for these devices, meaning that only 32-bit MSI addresses are allowed for them. However, on some platforms the MSI doorbell address is above the 32-bit limit but within the addressable range of the device. As a first step to enable MSI on those combinations of devices and platforms, convert the boolean no_64bit_msi flag to a DMA mask and fixup the affected usage sites: - no_64bit_msi = 1 -> msi_addr_mask = DMA_BIT_MASK(32) - no_64bit_msi = 0 -> msi_addr_mask = DMA_BIT_MASK(64) - if (no_64bit_msi) -> if (msi_addr_mask < DMA_BIT_MASK(64)) Since no values other than DMA_BIT_MASK(32) and DMA_BIT_MASK(64) are used, this is functionally equivalent. This prepares for changing the binary decision between 32 and 64 bit to a DMA mask based decision which allows to support systems which have a DMA address space less than 64bit but a MSI doorbell address above the 32-bit limit.
