2023-10-17drm/i915: Retry gtt fault when out of fence registersVille Syrjälä
If we can't find a free fence register to handle a fault in the GMADR range just return VM_FAULT_NOPAGE without populating the PTE so that userspace will retry the access and trigger another fault. Eventually we should find a free fence and the fault will get properly handled. A further improvement idea might be to reserve a fence (or one per CPU?) for the express purpose of handling faults without having to retry. But that would require some additional work. Looks like this may have gotten broken originally by commit 39965b376601 ("drm/i915: don't trash the gtt when running out of fences") as that changed the errno to -EDEADLK which wasn't handle by the gtt fault code either. But later in commit 2feeb52859fc ("drm/i915/gt: Fix -EDEADLK handling regression") I changed it again to -ENOBUFS as -EDEADLK was now getting used for the ww mutex dance. So this fix only makes sense after that last commit.

2023-10-17drm/i915/cx0: Only clear/set the Pipe Reset bit of the PHY Lanes OwnedKhaled Almahallawy
Currently, with MFD/pin assignment D, the driver clears the pipe reset bit of lane 1 which is not owned by display. This causes the display to block S0iX. By not clearing this bit for lane 1 and keeping whatever default, S0ix started to work. This is already what the driver does at the end of the phy lane reset sequence (Step#8) Bspec: 65451 Fixes: 619a06dba6fa ("drm/i915/mtl: Reset only one lane in case of MFD") Cc: Mika Kahola <mika.kahola@intel.com> Cc: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: Khaled Almahallawy <khaled.almahallawy@intel.com> Reviewed-by: Gustavo Sousa <gustavo.sousa@intel.com> Signed-off-by: Radhakrishna Sripada <radhakrishna.sripada@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20231005001310.154396-1-khaled.almahallawy@intel.com (cherry picked from commit 4a07f063d20c46524f00976f4537de72d9f31c4e) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2023-10-18LoongArch: Disable WUC for pgprot_writecombine() like ioremap_wc()Icenowy Zheng
Currently the code disables WUC only disables it for ioremap_wc(), which is only used when mapping writecombine pages like ioremap() (mapped to the kernel space). But for VRAM mapped in TTM/GEM, it is mapped with a crafted pgprot by the pgprot_writecombine() function, in which case WUC isn't disabled now. Disable WUC for pgprot_writecombine() (fallback to SUC) if needed, like ioremap_wc(). This improves the AMDGPU driver's stability (solves some misrendering) on Loongson-3A5000/3A6000 machines.

2023-10-17tcp: fix excessive TLP and RACK timeouts from HZ roundingNeal Cardwell
We discovered from packet traces of slow loss recovery on kernels with the default HZ=250 setting (and min_rtt < 1ms) that after reordering, when receiving a SACKed sequence range, the RACK reordering timer was firing after about 16ms rather than the desired value of roughly min_rtt/4 + 2ms. The problem is largely due to the RACK reorder timer calculation adding in TCP_TIMEOUT_MIN, which is 2 jiffies. On kernels with HZ=250, this is 2*4ms = 8ms. The TLP timer calculation has the exact same issue. This commit fixes the TLP transmit timer and RACK reordering timer floor calculation to more closely match the intended 2ms floor even on kernels with HZ=250. It does this by adding in a new TCP_TIMEOUT_MIN_US floor of 2000 us and then converting to jiffies, instead of the current approach of converting to jiffies and then adding th TCP_TIMEOUT_MIN value of 2 jiffies. Our testing has verified that on kernels with HZ=1000, as expected, this does not produce significant changes in behavior, but on kernels with the default HZ=250 the latency improvement can be large. For example, our tests show that for HZ=250 kernels at low RTTs this fix roughly halves the latency for the RACK reorder timer: instead of mostly firing at 16ms it mostly fires at 8ms.

However it's possible for the copros count to be elevated if a process exits without first closing file descriptors that are associated with a copro, eg. VAS. If the process exits with a VAS file still open, the release callback is queued up for exit_task_work() via: exit_files() put_files_struct() close_files() filp_close() fput() And called via: exit_task_work() ____fput() __fput() file->f_op->release(inode, file) coproc_release() vas_user_win_ops->close_win() vas_deallocate_window() mm_context_remove_vas_window() mm_context_remove_copro() But that is after exit_mm() has been called from do_exit() and triggered the warning. Fix it by dropping the warning, and always calling __flush_all_mm(). In the normal case of no copros, that will result in a call to _tlbiel_pid(mm->context.id, RIC_FLUSH_ALL) just as the current code does. If the copros count is elevated then it will cause a global flush, which should flush translations from any copros. Note that the process table entry was cleared in arch_exit_mmap(), so copros should not be able to fetch any new translations.

2023-10-17x86/boot: efistub: Assign global boot_params variableArd Biesheuvel
Now that the x86 EFI stub calls into some APIs exposed by the decompressor (e.g., kaslr_get_random_long()), it is necessary to ensure that the global boot_params variable is set correctly before doing so. Note that the decompressor and the kernel proper carry conflicting declarations for the global variable 'boot_params' so refer to it via an alias to work around this.

2023-10-16drm/mediatek: Correctly free sg_table in gem prime vmapChen-Yu Tsai
The MediaTek DRM driver implements GEM PRIME vmap by fetching the sg_table for the object, iterating through the pages, and then vmapping them. In essence, unlike the GEM DMA helpers which vmap when the object is first created or imported, the MediaTek version does it on request. Unfortunately, the code never correctly frees the sg_table contents. This results in a kernel memory leak. On a Hayato device with a text console on the internal display, this results in the system running out of memory in a few days from all the console screen cursor updates. Add sg_free_table() to correctly free the contents of the sg_table. This was missing despite explicitly required by mtk_gem_prime_get_sg_table(). Also move the "out" shortcut label to after the kfree() call for the sg_table. Having sg_free_table() together with kfree() makes more sense. The shortcut is only used when the object already has a kernel address, in which case the pointer is NULL and kfree() does nothing. Hence this change causes no functional change.

2023-10-16pinctrl: qcom: lpass-lpi: fix concurrent register updatesKrzysztof Kozlowski
The Qualcomm LPASS LPI pin controller driver uses one lock for guarding Read-Modify-Write code for slew rate registers. However the pin configuration and muxing registers have exactly the same RMW code but are not protected. Pin controller framework does not provide locking here, thus it is possible to trigger simultaneous change of pin configuration registers resulting in non-atomic changes. Protect from concurrent access by re-using the same lock used to cover the slew rate register. Using the same lock instead of adding second one will make more sense, once we add support for newer Qualcomm SoC, where slew rate is configured in the same register as pin configuration/muxing.

With the current cleanup flow, we could trigger a NULL pointer dereference if there is a delayed destruction of a BO with a system resource that gets executed on drain_workqueue() call, as we attempt to free a resource using an already released resource manager. Remove the device from the device list and drain its workqueue before releasing the system domain manager in ttm_device_fini().

2023-10-16ASoC: sigmadsp: Add __counted_by for struct sigmadsp_data and use struct_size()Gustavo A. R. Silva
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). While there, use struct_size() and size_sub() helpers, instead of the open-coded version, to calculate the size for the allocation of the whole flexible structure, including of course, the flexible-array member. This code was found with the help of Coccinelle, and audited and fixed manually. Signed-off-by: "Gustavo A. R.
