From: Álvaro Fernández Rojas Date: Fri, 10 May 2024 11:19:19 +0000 (+0200) Subject: bcm27xx: add 6.6 kernel patches X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8c405cdcccadc824cfdd189550cb0fcedacd8245;p=openwrt%2Fstaging%2Fwigyori.git bcm27xx: add 6.6 kernel patches The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

And since that commit +happens to be on a cursor plane, it's considered a legacy cursor update +by KMS. + +The main difference it makes is that it won't wait for its completion +(ie, next vblank) before returning. This means if we have multiple +commits happening in rapid succession, we can have several of them +happening before the next vblank. + +In parallel, our dlist allocation is tied to a CRTC state, and each time +we do a commit we end up with a new CRTC state, with the previous one +being freed. This means that we free our previous dlist entry (but don't +clear it though) every time a new one is being committed. + +Now, if we were to have two commits happening before the next vblank, we +could end up freeing reusing the same dlist entries before the next +vblank. + +Indeed, we would start from an initial state taking, for example, the +dlist entries 10 to 20, then start a commit taking the entries 20 to 30 +and setting the dlist pointer to 20, and freeing the dlist entries 10 to +20. However, since we haven't reach vblank yet, the HVS is still using +the entries 10 to 20. + +If we were to make a new commit now, chances are the allocator are going +to give the 10 to 20 entries back, and we would change their content to +match the new state. If vblank hasn't happened yet, we just corrupted +the active dlist entries. + +A first attempt to solve this was made by creating an intermediate dlist +buffer to store the current (ie, as of the last commit) dlist content, +that we would update each time the HVS is done with a frame. However, if +the interrupt handler missed the vblank window, we would end up copying +our intermediate dlist to the hardware one during the composition, +essentially creating the same issue. + +Since making sure that our interrupt handler runs within a fixed, +constrained, time window would require to make Linux a real-time kernel, +this seems a bit out of scope. + +Instead, we can work around our original issue by keeping the dlist +slots allocation longer. That way, we won't reuse a dlist slot while +it's still in flight. In order to achieve this, instead of freeing the +dlist slot when its associated CRTC state is destroyed, we'll queue it +in a list. + +A naive implementation would free the buffers in that queue when we get +our end of frame interrupt. However, there's still a race since, just +like in the shadow dlist case, we don't control when the handler for +that interrupt is going to run. Thus, we can end up with a commit adding +an old dlist allocation to our queue during the window between our +actual interrupt and when our handler will run.

@@ ++Introduction ++============ ++ ++This directory contains Device Tree overlays. Device Tree makes it possible ++to support many hardware configurations with a single kernel and without the ++need to explicitly load or blacklist kernel modules. Note that this isn't a ++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices ++are still configured by the board support code, but the intention is to ++eventually reach that goal. ++ ++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By ++default, the Raspberry Pi kernel boots with device tree enabled. You can ++completely disable DT usage (for now) by adding: ++ ++ device_tree= ++ ++to your config.txt, which should cause your Pi to revert to the old way of ++doing things after a reboot. ++ ++In /boot you will find a .dtb for each base platform. This describes the ++hardware that is part of the Raspberry Pi board. The loader (start.elf and its ++siblings) selects the .dtb file appropriate for the platform by name, and reads ++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) ++are disabled, but they can be enabled using Device Tree parameters: ++ ++ dtparam=i2c=on,i2s=on,spi=on ++ ++However, this shouldn't be necessary in many use cases because loading an ++overlay that requires one of those interfaces will cause it to be enabled ++automatically, and it is advisable to only enable interfaces if they are ++needed. ++ ++Configuring additional, optional hardware is done using Device Tree overlays ++(see below). ++ ++GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and ++not the physical pin numbers. ++ ++raspi-config ++============ ++ ++The Advanced Options section of the raspi-config utility can enable and disable ++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it ++is possible to both enable an interface and blacklist the driver, if for some ++reason you should want to defer the loading. ++ ++Modules ++======= ++ ++As well as describing the hardware, Device Tree also gives enough information ++to allow suitable driver modules to be located and loaded, with the corollary ++that unneeded modules are not loaded. As a result it should be possible to ++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can ++have its contents deleted (or commented out). ++ ++Using Overlays ++============== ++ ++Overlays are loaded using the "dtoverlay" config.txt setting. As an example, ++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded ++by writing a magic string comprising a device identifier and an I2C address to ++a special file in /sys/class/i2c-adapter, having first loaded the driver for ++the I2C interface and the RTC device - something like this: ++ ++ modprobe i2c-bcm2835 ++ modprobe rtc-ds1307 ++ echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device ++ ++With DT enabled, this becomes a line in config.txt: ++ ++ dtoverlay=i2c-rtc,ds1307 ++ ++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node" ++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By ++default it usees address 0x68, but this can be modified with an additional DT ++parameter: ++ ++ dtoverlay=i2c-rtc,ds1307,addr=0x68 ++ ++Parameters usually have default values, although certain parameters are ++mandatory. See the list of overlays below for a description of the parameters ++and their defaults. ++ ++Making new Overlays based on existing Overlays ++============================================== ++ ++Recent overlays have been designed in a more general way, so that they can be ++adapted to hardware by changing their parameters. When you have additional ++hardware with more than one device of a kind, you end up using the same overlay ++multiple times with other parameters, e.g. ++ ++ # 2 CAN FD interfaces on spi but with different pins ++ dtoverlay=mcp251xfd,spi0-0,interrupt=25 ++ dtoverlay=mcp251xfd,spi0-1,interrupt=24 ++ ++ # a realtime clock on i2c ++ dtoverlay=i2c-rtc,pcf85063 ++ ++While this approach does work, it requires knowledge about the hardware design. ++It is more feasible to simplify things for the end user by providing a single ++overlay as it is done the traditional way. ++ ++A new overlay can be generated by using ovmerge utility. ++https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge ++ ++To generate an overlay for the above configuration we pass the configuration ++to ovmerge and add the -c flag. ++ ++ ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \ ++ mcp251xfd-overlay.dts,spi0-1,interrupt=24 \ ++ i2c-rtc-overlay.dts,pcf85063 \ ++ >> merged-overlay.dts ++ ++The -c option writes the command above as a comment into the overlay as ++a marker that this overlay is generated and how it was generated. ++After compiling the overlay it can be loaded in a single line. ++ ++ dtoverlay=merged ++ ++It does the same as the original configuration but without parameters. ++ ++The Overlay and Parameter Reference ++=================================== ++ ++N.B.
