78076bb | Jens Axboe | 05 December 2019, 02:56:40 UTC | io_uring: use hash table for poll command lookups We recently changed this from a single list to an rbtree, but for some real life workloads, the rbtree slows down the submission/insertion case enough so that it's the top cycle consumer on the io_uring side. In testing, using a hash table is a more well rounded compromise. It is fast for insertion, and as long as it's sized appropriately, it works well for the cancellation case as well. Running TAO with a lot of network sockets, this removes io_poll_req_insert() from spending 2% of the CPU cycles.

f9bd84a | SeongJae Park | 26 November 2019, 15:36:05 UTC | xen/blkback: Avoid unmapping unmapped grant pages For each I/O request, blkback first maps the foreign pages for the request to its local pages. If an allocation of a local page for the mapping fails, it should unmap every mapping already made for the request. However, blkback's handling mechanism for the allocation failure does not mark the remaining foreign pages as unmapped. Therefore, the unmap function merely tries to unmap every valid grant page for the request, including the pages not mapped due to the allocation failure. On a system that fails the allocation frequently, this problem leads to following kernel crash.

To fix this move the setting of the zone size into the crticial sections blk_revalidate_disk_zones so that it gets updated together with the zone bitmaps and q->nr_zones.

After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time.

In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here. Core: - Add a clk provider API to get current parent index - Plug a memory leak in clk_unregister() path New Drivers: - CGU in Ingenix X1000 - Bitmain BM1880 clks - Qualcomm MSM8998 GPU clk controllers - Qualcomm SC7180 GCC and RPMH clk controllers - Qualcomm QCS404 Q6SSTOP clk controllers - Add support for the Renesas R-Car M3-W+ (r8a77961) SoC - Add support for the Renesas RZ/G2N (r8a774b1) SoC - Add Tegra20/30 External Memory Clock (EMC) support Updates: - Make gpio gate clks propagate rate setting up to parent - Prepare Armada 3700 for suspend to RAM by moving PCIe suspend/resume priority - Drop unused variables, enums, etc. in various clk drivers - Convert various drivers to use devm_platform_ioremap_resource() - Use struct_size() some more in various clk drivers - Improve Rockchip px30 clk tree - Add suspend/resume support to Tegra210 clk driver - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP - Allwinner DT exports and H6 clk tree fixes - Proper clk and reset handling for OMAP SoCs - Revamped TI divider clk to clamp max divider - Make 1443X/1416X PLL clock structure common for reusing among i.MX8 SoCs - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used - Add VIDEO2_PLL clock for imx8mq - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs - Add sm1 support in the Amlogic audio clock controller - Switch some clocks on R-Car Gen2/3 to .determine_rate() - Remove Renesas R-Car Gen2 legacy DT clock support - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3 - Improve Renesas R-Car Gen3 SD clock handling - Add rate table for Samsung exynos542x GPU and VPLL clks - Fix potential CPU performance degradation after system suspend/resume cycle on exynos542x SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (160 commits) clk: aspeed: Add RMII RCLK gates for both AST2500 MACs MAINTAINERS: Add entry for BM1880 SoC clock driver clk: Add common clock driver for BM1880 SoC dt-bindings: clock: Add devicetree binding for BM1880 SoC clk: Add clk_hw_unregister_composite helper function definition clk: Zero init clk_init_data in helpers clk: ingenic: Allow drivers to be built with COMPILE_TEST MAINTAINERS: Update section for Ux500 clock drivers clk: mark clk_disable_unused() as __init clk: Fix memory leak in clk_unregister() clk: Ingenic: Add CGU driver for X1000. dt-bindings: clock: Add X1000 bindings. clk: tegra: Use match_string() helper to simplify the code clk: pxa: fix one of the pxa RTC clocks clk: sprd: Use IS_ERR() to validate the return value of syscon_regmap_lookup_by_phandle() clk: armada-xp: remove unused code clk: tegra: Fix build error without CONFIG_PM_SLEEP clk: tegra: Add missing stubs for the case of !CONFIG_PM_SLEEP clk: tegra: Optimize PLLX restore on Tegra20/30 clk: tegra: Add suspend and resume support on Tegra210 ... | 02 December 2019, 00:06:02 UTC |

This is single commit that just deletes code. Leaving just enough code so that the deprecated sysctl warning continues to be printed. If my analysis turns out to be wrong and someone actually cares it will be easy to revert this commit and have the system call again. There was one new xtensa defconfig in linux-next that enabled the system call this cycle and when asked about it the maintainer of the code replied that it was not enabled on purpose. As of today's linux-next tree that defconfig no longer enables the system call. What we saw in the review discussion was that if we go a step farther than my patch and mess with uapi headers there are pieces of code that won't compile, but nothing minds the system call actually disappearing from the kernel" Link: https://lore.kernel.org/lkml/201910011140.EA0181F13@keescook/ * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: sysctl: Remove the sysctl system call | 01 December 2019, 21:26:18 UTC |

It makes a number of significant changes: - It removes the nr_exclusive argument from __wake_up_sync_key() as this is always 1. This prepares for the next step: - Adds wake_up_interruptible_sync_poll_locked() so that poll can be woken up from a function that's holding the poll waitqueue spinlock. - Change the pipe buffer ring to be managed in terms of unbounded head and tail indices rather than bounded index and length. This means that reading the pipe only needs to modify one index, not two. - A selection of helper functions are provided to query the state of the pipe buffer, plus a couple to apply updates to the pipe indices. - The pipe ring is allowed to have kernel-reserved slots. This allows many notification messages to be spliced in by the kernel without allowing userspace to pin too many pages if it writes to the same pipe. - Advance the head and tail indices inside the pipe waitqueue lock and use wake_up_interruptible_sync_poll_locked() to poke poll without having to take the lock twice. - Rearrange pipe_write() to preallocate the buffer it is going to write into and then drop the spinlock. This allows kernel notifications to then be added the ring whilst it is filling the buffer it allocated. The read side is stalled because the pipe mutex is still held. - Don't wake up readers on a pipe if there was already data in it when we added more. - Don't wake up writers on a pipe if the ring wasn't full before we removed a buffer" * tag 'notifications-pipe-prep-20191115' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: pipe: Remove sync on wake_ups pipe: Increase the writer-wakeup threshold to reduce context-switch count pipe: Check for ring full inside of the spinlock in pipe_write() pipe: Remove redundant wakeup from pipe_write() pipe: Rearrange sequence in pipe_write() to preallocate slot pipe: Conditionalise wakeup in pipe_read() pipe: Advance tail pointer inside of wait spinlock in pipe_read() pipe: Allow pipes to have kernel-reserved slots pipe: Use head and tail pointers for the ring, not cursor and length Add wake_up_interruptible_sync_poll_locked() Remove the nr_exclusive argument from __wake_up_sync_key() pipe: Reduce #inclusion of pipe_fs_i.h | 30 November 2019, 22:12:13 UTC |

0a6cad5 | Dave Airlie | 28 November 2019, 02:39:50 UTC | Merge branch 'vmwgfx-coherent' of git://people.freedesktop.org/~thomash/linux into drm-next Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver to provide coherent graphics memory, meaning that the GPU sees any content written to the coherent memory on the next GPU operation that touches that memory, and the CPU sees any content written by the GPU to that memory immediately after any fence object trailing the GPU operation is signaled. Paravirtual drivers that otherwise require explicit synchronization needs to do this by hooking up dirty tracking to pagefault handlers and buffer object validation. Provide mm helpers needed for this and that also allow for huge pmd- and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7). The code has been tested and exercised by a tailored version of mesa where we disable all explicit synchronization and assume graphics memory is coherent. The performance loss varies of course; a typical number is around 5%.
