2022-02-10drm/fb-helper: Calculate damaged area in separate helperThomas Zimmermann1-6/+20
Add drm_fb_helper_memory_range_to_clip(), a helper function that accepts an linear range of video memory and converts it into a rectangle. The computed rectangle describes the damaged area in terms of scanlines and pixels per scanline. While at it, make the code more readable by using struct drm_rect and related helpers. The code was previously part of the deferred I/O helpers, but is also useful for damage handling of regular write operations. Update the deferred I/O code to use the new function. v2: * rename helper (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220209161617.3553-4-tzimmermann@suse.de
2022-02-10drm/fb-helper: Fix vertical damage clippingThomas Zimmermann1-2/+1
Don't clip the damage rectangle against the viewport. This only works if the viewport is located at the beginning of the video memory and the video memory doesn't extend the screen (i.e., if there's no overallocation). Fbdev emulation transfers data from write operations into a possible shadow buffer, then into a GEM buffer object, and finally via graphics driver onto the screen. If callers write outside the currently visible area, clipping the damage rectangle against the viewport will loose these updates in the shadow buffer and the fbdev's buffer object will contain stale data. Panning the viewport to the stale area of the buffer will display obsolete data. Instead, mark all written areas as damaged, so that the damage handler updates the buffer object from the shadow buffer for all such areas. The graphics driver's later has the option of clipping the damaged area against the viewport when updating the screen from the buffer object.

2022-02-10drm/fb-helper: Fix clip rectangle heightThomas Zimmermann1-1/+1
Computing the clip rectangle is prone to off-by-one errors when writes happen near the end of a memory page. Point the end of the memory area to the first trailing byte, so that (end - start) returns the area's length.

Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2022-02-09 This series contains updates to ice driver only. Brett adds support for QinQ. This begins with code refactoring and re-organization of VLAN configuration functions to allow for introduction of VSI VLAN ops to enable setting and calling of respective operations based on device support of single or double VLANs. Implementations are added for outer VLAN support. To support QinQ, the device must be set to double VLAN mode (DVM). In order for this to occur, the DDP package and NVM must also support DVM. Functions to determine compatibility and properly configure the device are added as well as setting the proper bits to advertise and utilize the proper offloads. Support for VIRTCHNL_VF_OFFLOAD_VLAN_V2 is also included to allow for VF to negotiate and utilize this functionality. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.

2022-02-10spi: mxic: Add support for pipelined ECC operationsMiquel Raynal2-2/+112
Some SPI-NAND chips do not have a proper on-die ECC engine providing error correction/detection. This is particularly an issue on embedded devices with limited resources because all the computations must happen in software, unless an external hardware engine is provided. These external engines are new and can be of two categories: external or pipelined. Macronix is providing both, the former being already supported. The second, however, is very SoC implementation dependent and must be instantiated by the SPI host controller directly. An entire subsystem has been contributed to support these engines which makes the insertion into another subsystem such as SPI quite straightforward without the need for a lot of specific functions.

2022-02-10mtd: spinand: Create direct mapping descriptors for ECC operationsMiquel Raynal1-2/+33
In order for pipelined ECC engines to be able to enable/disable the ECC engine only when needed and avoid races when future parallel-operations will be supported, we need to provide the information about the use of the ECC engine in the direct mapping hooks. As direct mapping configurations are meant to be static, it is best to create two new mappings: one for regular 'raw' accesses and one for accesses involving correction. It is up to the driver to use or not the new ECC enable boolean contained in the spi-mem operation. As dirmaps are not free (they consume a few pages of MMIO address space) and because these extra entries are only meant to be used by pipelined engines, let's limit their use to this specific type of engine and save a bit of memory with all the other setups.

2022-02-10spi: spi-mem: Add an ecc parameter to the spi_mem_op structureMiquel Raynal1-0/+5
Soon the SPI-NAND core will need a way to request a SPI controller to enable ECC support for a given operation. This is because of the pipelined integration of certain ECC engines, which are directly managed by the SPI controller itself. Introduce a spi_mem_op additional field for this purpose: ecc. So far this field is left unset and checked to be false by all the SPI controller drivers in their ->supports_op() hook, as they all call spi_mem_default_supports_op().

If no firmware was present at all (or, presumably, all of the firmware files failed to parse), we end up unbinding by calling device_release_driver(), which calls remove(), which then in iwlwifi calls iwl_drv_stop(), freeing the 'drv' struct. However the new code I added will still erroneously access it after it was freed. Set 'failure=false' in this case to avoid the access, all data was already freed anyway.

2022-02-10cpufreq: CPPC: Fix performance/frequency conversionPierre Gondois1-22/+21
CPUfreq governors request CPU frequencies using information on current CPU usage. The CPPC driver converts them to performance requests. Frequency targets are computed as: target_freq = (util / cpu_capacity) * max_freq target_freq is then clamped between [policy->min, policy->max]. The CPPC driver converts performance values to frequencies (and vice-versa) using cppc_cpufreq_perf_to_khz() and cppc_cpufreq_khz_to_perf(). These functions both use two different factors depending on the range of the input value. For cppc_cpufreq_khz_to_perf(): - (NOMINAL_PERF / NOMINAL_FREQ) or - (LOWEST_PERF / LOWEST_FREQ) and for cppc_cpufreq_perf_to_khz(): - (NOMINAL_FREQ / NOMINAL_PERF) or - ((NOMINAL_PERF - LOWEST_FREQ) / (NOMINAL_PERF - LOWEST_PERF)) This means: 1- the functions are not inverse for some values: (perf_to_khz(khz_to_perf(x)) != x) 2- cppc_cpufreq_perf_to_khz(LOWEST_PERF) can sometimes give a different value from LOWEST_FREQ due to integer approximation 3- it is implied that performance and frequency are proportional (NOMINAL_FREQ / NOMINAL_PERF) == (LOWEST_PERF / LOWEST_FREQ) This patch changes the conversion functions to an affine function. This fixes the 3 points above.
