From f7ec3f62d7736ed14050716943a9562879155fcc Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Thu, 8 Sep 2022 12:43:34 +0200 Subject: media: remove reference to CONFIG_EMBEDDED in MEDIA_SUPPORT_FILTER The config EMBEDDED selects EXPERT, i.e., when EMBEDDED is enabled, EXPERT is usually also enabled. Hence, it sufficient to have the option MEDIA_SUPPORT_FILTER set to y if !EXPERT. This way, MEDIA_SUPPORT_FILTER does not refer to CONFIG_EMBEDDED anymore and allows us to remove CONFIG_EMBEDDED in the close future. Remove the reference to CONFIG_EMBEDDED in MEDIA_SUPPORT_FILTER.

More importantly, the whole situation can be avoided and the driver simplified by converting it over to the relatively new usb_control_msg_recv() and usb_control_msg_send() routines. That's what this fix does.

Replace it with the correct macro, and rename it from RKISP1_CIF_ISP_LSC_GRAD_SIZE() to RKISP1_CIF_ISP_LSC_SECT_GRAD() as the corresponding registers store the gradients for each sector, not a size. This doesn't cause any functional change as the two macros are defined identically (the size and gradient registers store fields in the same number of bits at the same positions).

The driver currently configures all ISP initial parameters before enabling the ISP, which causes the LSC RAM to not be initialized properly. To fix this, split the rkisp1_params_configure() function into a rkisp1_params_pre_configure() and a rkisp1_params_post_configure(). The former configures all ISP parameters but LSC, while the latter configures LSC. To implement this, the rkisp1_params_apply_params_cfg() function is deconstructed, with two small helpers created to deal with the parameters buffers, which are then used in rkisp1_params_isr(), rkisp1_params_pre_configure() and rkisp1_params_post_configure(). While this initialization ordering is only needed for the ISP8000Nano v18.02, it doesn't affect other ISP versions negatively, and can thus be followed unconditionally.

As the drivers currently use the pipelines with the entity based model, moving the pipelines to pads will cause changes to the drivers. However, most of the uses of media pipelines are related to a video device (a DMA engine) with a single pad, and thus there's never a need to support multiple pads in these use cases. We can avoid pushing the complexities of the pad based model to the drivers by adding video device wrappers for the pipeline related functions. This patch adds a number of wrappers to media_pipeline functions, all of which take a video_device as a parameter (instead of a media_entity), and verify that there's just one pad.

The graph walk traverses the media graph following links between the entities. Also, while the pipeline can't change between the start and stop calls, the graph is walked again from scratch at stop time, or any time a driver needs to inspect the pipeline. With the upcoming multiplexed streams support we will need a bit more intelligent pipeline construction, as e.g. two independent streams may be passing through a single entity via separate pads in which case those pads should not be part of the same pipeline. This patch essentially rewrites the media_pipeline_start/stop so that a pipeline is defined as a set of pads instead of entities and the media graph traversal considers the pad interdependencies when choosing which links to follow. Currently all the entity's pads are considered as interdependent. This means that the behavior with all the current drivers stays the same, but in the future we can define a more fine-grained pipeline construction. Additionally the media pipeline's pads are cached at media_pipeline_start() time, and re-used at media_pipeline_stop() which avoid the need to re-walk the whole graph as the previous implementation did. Also, caching pads in the pipeline can serve in the future as the foundation to provide a better API than the media graph walk to drivers to iterate over pads and entities in the pipeline. Note that the old media_pipeline_start/stop used the media graph walk API. The new version does not use the media graph walk API, but instead a new implementation. There are two reasons for not changing the graph walk: it proved to be rather difficult to change the graph walk to have the features implemented in this patch, and second, this keeps the backward compatibility of the graph walk as there are users of the graph walk API The long term plan is that all the existing code would be converted to use the new cached pipeline, thus allowing us to remove the graph walk.

Potentially returning an unsupported resolution to userspace, which VIDIOC_TRY_FMT is not supposed to do. atomisp_set_fmt() also uses atomisp_try_fmt() and relies on this wrong behavior. The VIDIOC_TRY_FMT call passes NULL for the res_overflow argument where as the atomisp_set_fmt() call passes non NULL. Use the res_overflow argument to differentiate between the 2 callers and always propagate the sensors result in the VIDIOC_TRY_FMT case. This fixes the resolution list in camorama showing resolutions like e.g. 1584x1184 instead of 1600x1200.

Note the main reason for removing this is because it depends on the videobuf (version 1) outq and we want to remove or replace all videobuf usage in the driver.

Yet it uses the same file-ops and ioctl-ops even though it does not have a videobuf queue, which makes e.g. the mmap fop nonsense. Worse the only file-ops / ioctls which differentiate between the 2 types and correctly do container_of on the right type are the open/release fops and the vidioc_default handler. The mmap and poll fops and *all* other ioctl handlers unconditionally do container_of on the passed in struct video_device blindly assuming they are dealing with the one embedded in the atomisp_video_pipe struct. This makes it trivial for userspace to cause all sort of undefined behavior by calling mmap, poll or the other ioctls on the ACC device node! Presumably the use of the ACC device node was to allow making the special ioctls to load custom programs while the other /dev/video# nodes were already open, since the /dev/video# nodes can currently all be opened only once (which needs to be fixed). commit 4bbca788b6eb ("media: atomisp: remove private acceleration ioctls") has removed the custom ATOMISP_ACC_* ioctls, so there no longer is any reason to keep the ACC device node. As explained above its presence can easily cause the kernel to crash, so remove the ACC device node and the code for handling it.

All the changes in this patch are just s/rt_mutex/mutex/. This is a preparation patch for switching the ioctl locking over to using the video_dev.lock member so that the v4l2-core takes care of the locking.

Writers of streaming must hold both isp->mutex and isp->lock. 2. Readers of streaming need to hold only one of the two locks. Not all writers where properly taking both locks this fixes this. In the case of the readers, many readers depend on their caller to hold isp->mutex, add asserts for this And in the case of atomisp_css_get_dis_stat() it is called with isp->mutex held, so there is no need to take the spinlock just for reading the streaming value.

Note this changes the vidioc_s_fmt_vid_cap and vidioc_s_input handlers to now reject calls made while asd->streaming==STOPPING. This fixes a possible race where one thread can make this ioctls while vidioc_streamoff is running from another thread and it has temporarily released isp->mutex to kill the watchdog timers / work.

There is no way to do fault injection and normally the ISP does not get stuck, so is it is impossible to test it. 2. It in essence just stops all streams, resets the ISP and then brings everything back up. Userspace can easily do this itself by using a timeout on dqbuf and then closing (which causes a poweroff) + re-opening the device. Doing this in userspace (if it ever turns out to be necessary) greatly simplifies the kernel code and in general will be a more robust solution. Even just a quick look at the code finds several more issues: 3. The need to sync-cancel the timers + work on streamoff requires isp->mutex to be dropped halfway during the ioctl opening all sorts of races. 4. The atomisp code supports setting up 2 pipelines, streaming from two sensors at the same time. But there is only a single wdt_work and stopping one of the 2 streams will cancel the timers + work, stopping the wdt even though the other stream might still be running. 5. In case atomisp_css_flush() the sync cancel is done while keeping isp->mutex locked, causing a deadlock when racing with wdt_work which also takes isp->mutex. 6. Even though the watchdog is purely a software/driver thing which just checkes that new frames keep coming in, there are 2 completely different implementations for the ISP2400/ISP2401 which is not necessary at all. So all in all I believe that it is better to just remove the current watchdog implementation. Fixing all the issues with the current implementation will be so much work, that if it turns out that we do need something like this then doing a clean re-implementation from scratch will be better anyways. wdt_work was also (ab)used to reset the ISP after the firmware signalled an fw-assert error through the irq, add a new assert_recover_work to replace this.

In order to set it up properly, in vc4_hdmi_audio_init(), our HDMI driver will register a device matching the HDMI codec driver, and then register an ASoC card using that codec. However, if vc4 is compiled as a module, chances are that the hdmi-codec driver will be too. In such a case, the module loader will have a very narrow window to load the module between the device registration and the card registration. If it fails to load the module in time, the card registration will fail with EPROBE_DEFER, and we'll abort the audio initialisation, unregistering the HDMI codec device in the process. The next time the bind callback will be run, it's likely that we end up missing that window again, effectively preventing vc4 to probe entirely. In order to prevent this, we can create a soft dependency of the vc4 driver on the HDMI codec one so that we're sure the HDMI codec will be loaded before the VC4 module is, and thus we'll never end up in the previous situation.

It turns out that we can't downright remove that code from the driver, since the Pi0-3 and Pi4 are in different cases, and it only works for the Pi4. Indeed, the commit mentioned above was relying on the RaspberryPi firmware clocks driver to initialize the rate if it wasn't done by the firmware. However, the Pi0-3 are using the clk-bcm2835 clock driver that wasn't doing this initialization. We therefore end up with the clock not being assigned a rate, and the CPU stalling when trying to access a register. We can't move that initialization in the clk-bcm2835 driver, since the HSM clock we depend on is actually part of the HDMI power domain, so any rate setup is only valid when the power domain is enabled. Thus, we reinstated the minimum rate setup at runtime_suspend, which should address both issues.

Arguably, getting the one that's running the code in there is confusing. For this reason, simply give the control CPU role to the first online one which automatically will be CPU0 if it is online, so one check can be dropped from the code for an added benefit.

I'll re-summarize here but you can also re-read the original commit. On trogdor devices, the BIOS is setting up the SPI chip select as: - mux special function (SPI chip select) - output enable - output low (unused because we've muxed as special function) In the kernel, however, we've moved away from using the chip select line as special function. Since the kernel wants to fully control the chip select it's far more efficient to treat the line as a GPIO rather than sending packet-like commands to the GENI firmware every time we want the line to toggle. When we transition from how the BIOS had the pin configured to how the kernel has the pin configured we end up glitching the line. That's because we _first_ change the mux of the line and then later set its output. This glitch is bad and can confuse the device on the other end of the line. The old commit e440e30e26dd ("arm64: dts: qcom: sc7180: Avoid glitching SPI CS at bootup on trogdor") fixed the glitch, though the solution was far from elegant. It essentially did the thing that everyone always hates: encoding a sequential program in device tree, even if it's a simple one. It also, unfortunately, got broken by commit b991f8c3622c ("pinctrl: core: Handling pinmux and pinconf separately"). After that commit we did all the muxing _first_ even though the config (set the pin to output high) was listed first. :( I looked at ideas for how to solve this more properly. My first thought was to use the "init" pinctrl state. In theory the "init" pinctrl state is supposed to be exactly for achieving glitch-free transitions. My dream would have been for the "init" pinctrl to do nothing at all. That would let us delay the automatic pin muxing until the driver could set things up and call pinctrl_init_done(). In other words, my dream was: /* Request the GPIO; init it 1 (because DT says GPIO_ACTIVE_LOW) */ devm_gpiod_get_index(dev, "cs", GPIOD_OUT_LOW); /* Output should be right, so we can remux, yay! */ pinctrl_init_done(dev); Unfortunately, it didn't work out. The primary reason is that the MSM GPIO driver implements gpio_request_enable(). As documented in pinmux.h, that function automatically remuxes a line as a GPIO. ...and it does this remuxing _before_ specifying the output of the pin. You can see in gpiod_get_index() that we call gpiod_request() before gpiod_configure_flags(). gpiod_request() isn't passed any flags so it has no idea what the eventual output will be. We could have debates about whether or not the automatic remuxing to GPIO for the MSM pinctrl was a good idea or not, but at this point I think there is a plethora of code that's relying on it and I certainly wouldn't suggest changing it. Alternatively, we could try to come up with a way to pass the initial output state to gpio_request_enable() and plumb all that through. That seems like it would be doable, but we'd have to plumb it through several layers in the stack. This patch implements yet another alternative. Here, we specifically avoid glitching the first time a pin is muxed to GPIO function if the direction of the pin is output. The idea is that we can read the state of the pin before we set the mux and make sure that the re-mux won't change the state. NOTES: - We only do this the first time since later swaps between mux states might want to preserve the old output value. In other words, I wouldn't want to break a driver that did: gpiod_set_value(g, 1); pinctrl_select_state(pinctrl, special_state); pinctrl_select_default_state(); /* We should be driving 1 even if "special_state" made the pin 0 */ - It's safe to do this the first time since the driver _couldn't_ have explicitly set a state. In order to even be able to control the GPIO (at least using gpiod) we have to have requested it which would have counted as the first mux. - In theory, instead of keeping track of the first time a pin was set as a GPIO we could enable the glitch-free behavior only when msm_pinmux_request_gpio() is in the callchain. That works an enables my "dream" implementation above where we use an "init" state to solve this. However, it's nice not to have to do this. By handling just the first transition to GPIO we can simply let the normal "default" remuxing happen and we can be assured that there won't be a glitch. Before this change I could see the glitch reported on the EC console when booting. It would say this when booting the kernel: Unexpected state 1 in CSNRE ISR After this change there is no error reported. Note that I haven't reproduced the original problem described in e440e30e26dd ("arm64: dts: qcom: sc7180: Avoid glitching SPI CS at bootup on trogdor") but I could believe it might happen in certain timing conditions.

The following line defines a pointer that point to a char buffer stored in read-only memory: char *pvs_name = "speedXX-pvsXX-vXX"; This pointer is meant to hold a template "speedXX-pvsXX-vXX" where the XX values get overridden by the qcom_cpufreq_krait_name_version function. Since the template is actually stored in read-only memory, when the function executes the following call we get an oops: snprintf(*pvs_name, sizeof("speedXX-pvsXX-vXX"), "speed%d-pvs%d-v%d", speed, pvs, pvs_ver); To fix this issue, we instead store the template name onto the stack by using the following syntax: char pvs_name_buffer[] = "speedXX-pvsXX-vXX"; Because the `pvs_name` needs to be able to be assigned to NULL, the template buffer is stored in the pvs_name_buffer and not under the pvs_name variable.

It turned out that the nvme_get_log() method invocation caused the nvme_hwmon_data structure instance corruption. In particular the nvme_hwmon_data.ctrl pointer was overwritten either with zeros or with garbage. After some research we discovered that the problem happened even before the actual NVME DMA execution, but during the buffer mapping. Since our platform is DMA-noncoherent, the mapping implied the cache-line invalidations or write-backs depending on the DMA-direction parameter. In case of the NVME SMART log getting the DMA was performed from-device-to-memory, thus the cache-invalidation was activated during the buffer mapping. Since the log-buffer isn't cache-line aligned, the cache-invalidation caused the neighbour data to be discarded. The neighbouring data turned to be the data surrounding the buffer in the framework of the nvme_hwmon_data structure. In order to fix that we need to make sure that the whole log-buffer is defined within the cache-line-aligned memory region so the cache-invalidation procedure wouldn't involve the adjacent data. One of the option to guarantee that is to kmalloc the DMA-buffer [1]. Seeing the rest of the NVME core driver prefer that method it has been chosen to fix this problem too. Note after a deeper researches we found out that the denoted commit wasn't a root cause of the problem.

charset=UTF-8 Content-Transfer-Encoding: 8bit Commit c347a787e34cb (drbd: set ->bi_bdev in drbd_req_new) moved a bio_set_dev call (which has since been removed) to "earlier", from drbd_request_prepare to drbd_req_new. The problem is that this accesses device->ldev->backing_bdev, which is not NULL-checked at this point. When we don't have an ldev (i.e. when the DRBD device is diskless), this leads to a null pointer deref. So, only allocate the private_bio if we actually have a disk. This is also a small optimization, since we don't clone the bio to only to immediately free it again in the diskless case.

This reordering uncovered a different hw programming ordering dependency in some APUs where the SDMA doorbells need to be programmed before the GFX doorbells. To fix this, move the SDMA doorbell programming back into the soc15 common code, but use the actual doorbell range values directly rather than the values stored in the ring structure since those will not be initialized at this point. This is a partial revert, but with the doorbell assignment fixed so the proper doorbell index is set before it's used.

This was necessary because there are actually two images that need to be signed: the kernel with the EFI stub attached, and the decompressor application. This is a bit of a burden, because it means that the images must be signed on the the same system that performs the build, and this is not realistic for distros. During the next cycle, we will introduce changes to the zboot code so that the inner image no longer needs to be signed. This means that the outer PE/COFF image can be handled as usual, and be signed later in the release process. Let's remove the associated Kconfig options now so that they don't end up in a LTS release while already being deprecated.

This inadvertently broke setting variables on firmware implementations that lack the QueryVariableInfo() boot service, because we no longer tolerate a EFI_UNSUPPORTED result from check_var_size() when calling efivar_entry_set_get_size(), which now ends up calling check_var_size() a second time inadvertently. If QueryVariableInfo() is missing, we support writes of up to 64k - let's move that logic into check_var_size(), and drop the redundant call.

In this case, it populates the virtual address fields of the runtime regions in the memory map with the physical address of each region, so that the mapping code has to be none the wiser. Only if SetVirtualAddressMap() fails, the virtual addresses are wiped and the kernel code knows that the regions cannot be mapped. However, wiping amounts to setting it to zero, and if a runtime region happens to live at physical address 0, its valid 1:1 mapped virtual address could be mistaken for a wiped field, resulting on loss of access to the EFI services at runtime. So let's only assume that VA == 0 means 'no runtime services' if the region in question does not live at PA 0x0.

However, if CONFIG_MACSEC is set, rtnl_lock is acquired both from aq_nic_service_task and aq_linkstate_threaded_isr. Then a deadlock happens if aq_nic_stop tries to cancel/disable them when they've already started their execution. As the deadlock is caused by rtnl_lock, it causes many other processes to stall, not only atlantic related stuff. Fix it by introducing a mutex that protects each NIC's macsec related data, and locking it instead of the rtnl_lock from the service task and the threaded IRQ. Before this patch, all macsec data was protected with rtnl_lock, but maybe not all of it needs to be protected. With this new mutex, further efforts can be made to limit the protected data only to that which requires it. However, probably it doesn't worth it because all macsec's data accesses are infrequent, and almost all are done from macsec_ops or ethtool callbacks, called holding rtnl_lock, so macsec_mutex won't never be much contended. The issue appeared repeteadly attaching and deattaching the NIC to a bond interface. Doing that after this patch I cannot reproduce the bug.
