2023-02-13drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()Imre Deak
Atm, drm_dp_remove_payload() uses the same payload state to both get the vc_start_slot required for the payload removal DPCD message and to deduct time_slots from vc_start_slot of all payloads after the one being removed. The above isn't always correct, as vc_start_slot must be the up-to-date version contained in the new payload state, but time_slots must be the one used when the payload was previously added, contained in the old payload state. The new payload's time_slots can change vs. the old one if the current atomic commit changes the corresponding mode. This patch let's drivers pass the old and new payload states to drm_dp_remove_payload(), but keeps these the same for now in all drivers not to change the behavior. A follow-up i915 patch will pass in that driver the correct old and new states to the function.

drm-next This time we've added support for reporting of GPU load via the common fdinfo format, as already supported by multiple other drivers. Improved diagnostic messages for MMU faults. And finally added experimental support for driving the VeriSilicon NPU cores, which are very close relatives to the GPU designs, so close in fact that they can run the same compute instruction set, but with a big NN-fabric/matrix/tensor execution array glued to the side.

2023-02-07drm/client: fix circular reference counting issueChristian König
We reference dump buffers both by their handle as well as their object. The problem is now that when anybody iterates over the DRM framebuffers and exports the underlying GEM objects through DMA-buf we run into a circular reference count situation. The result is that the fbdev handling holds the GEM handle preventing the DMA-buf in the GEM object to be released. This DMA-buf in turn holds a reference to the driver module which on unload would release the fbdev. Break that loop by releasing the handle as soon as the DRM framebuffer object is created. The DRM framebuffer and the DRM client buffer structure still hold a reference to the underlying GEM object preventing its destruction.

Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable.

https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next This tag contains habanalabs driver and accel changes for v6.3: - Moved the driver to the accel subsystem. Currently only the files were moved (including the uapi file which was also renamed). This doesn't include registering to the accel subsystem. This will probably be only in the next kernel version. - In case of decoder error (axi error) in Gaudi2, we can now find the exact IP that initiated the erroneous transaction and print the details for better debug. - Add more trace events. We now can trace mmio transactions and communication with the preboot firmware. - Add to Gaudi2 support for abrupt reset that is done by the firmware. This was support so far only for Gaudi1. - Add uAPI to flush memory transactions (to the device memory). This is needed by the communications library in case of doing p2p with a host NIC which access our HBM directly through the PCI BAR. - Add uAPI to pass-through a request from user-space to firmware and get the result back to user-space. This will allow the driver code to avoid the need to add new packet (in the communication channel with the firmware) for every new request type. - Remove the option to export dma-buf by memory allocation handle in our uAPI. This was planned for Gaudi2 but was never used. Instead, we will do export by memory address (same as Gaudi1). In addition, we added the option to specify an offset to the address. This is needed in Gaudi2 because there the user allocates the entire HBM in one allocation, but would like to export only small part of it. - Multiple bug fixes, refactors and small optimizations.

2023-01-26accel: Add .mmap to DRM_ACCEL_FOPSJeffrey Hugo
In reviewing the ivpu driver, DEFINE_DRM_ACCEL_FOPS could have been used if DRM_ACCEL_FOPS defined .mmap to be drm_gem_mmap. Lets add that since accel drivers are a variant of drm drivers, modern drm drivers are expected to use GEM, and mmap() is a common operation that is expected to be heavily used in accel drivers thus the common accel driver should be able to just use DEFINE_DRM_ACCEL_FOPS() for convenience.

Signal failed hotplugging with a flag in struct drm_client_dev. If set, the client helpers will not further try to set up the fbdev display.

2023-01-24drm/fb-helper: Use a per-driver FB deferred I/O handlerJavier Martinez Canillas
The DRM fbdev emulation layer sets the struct fb_info .fbdefio field to a struct fb_deferred_io pointer, that is shared across all drivers that use the generic drm_fbdev_generic_setup() helper function. It is a problem because the fbdev core deferred I/O logic assumes that the struct fb_deferred_io data is not shared between devices, and it's stored there state such as the list of pages touched and a mutex that is use to synchronize between the fb_deferred_io_track_page() function that track the dirty pages and fb_deferred_io_work() workqueue handler doing the actual deferred I/O. The latter can lead to the following error, since it may happen that two drivers are probed and then one is removed, which causes the mutex bo be destroyed and not existing anymore by the time the other driver tries to grab it for the fbdev deferred I/O logic: [ 369.756553] ------------[ cut here ]------------ [ 369.756604] DEBUG_LOCKS_WARN_ON(lock->magic != lock) [ 369.756631] WARNING: CPU: 2 PID: 1023 at kernel/locking/mutex.c:582 __mutex_lock+0x348/0x424 [ 369.756744] Modules linked in: nf_conntrack_netbios_ns nf_conntrack_broadcast nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ip v6 nf_defrag_ipv4 ip_set nf_tables nfnetlink qrtr btsdio bluetooth sunrpc brcmfmac snd_soc_hdmi_codec cpufreq_dt cfg80211 vfat fat vc4 rfkill brcmutil raspberrypi_cpufreq i2c_bcm2835 iproc_rng200 bcm2711_thermal snd_soc_core snd_pcm_dmaen gine leds_gpio nvmem_rmem joydev hid_cherry uas usb_storage gpio_raspberrypi_exp v3d snd_pcm raspberrypi_hwmon gpu_sched bcm2835_wdt broadcom bcm_phy_lib snd_timer genet snd mdio_bcm_unimac clk_bcm2711_dvp soundcore drm_display_helper pci e_brcmstb cec ip6_tables ip_tables fuse [ 369.757400] CPU: 2 PID: 1023 Comm: fbtest Not tainted 5.19.0-rc6+ #94 [ 369.757455] Hardware name: raspberrypi,4-model-b Raspberry Pi 4 Model B Rev 1.4/Raspberry Pi 4 Model B Rev 1.4, BIOS 2022.10 10/01/2022 [ 369.757538] pstate: 00400005 (nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 369.757596] pc : __mutex_lock+0x348/0x424 [ 369.757635] lr : __mutex_lock+0x348/0x424 [ 369.757672] sp : ffff80000953bb00 [ 369.757703] x29: ffff80000953bb00 x28: ffff17fdc087c000 x27: 0000000000000002 [ 369.757771] x26: ffff17fdc349f9b0 x25: fffffc5ff72e0100 x24: 0000000000000000 [ 369.757838] x23: 0000000000000000 x22: 0000000000000002 x21: ffffa618df636f10 [ 369.757903] x20: ffff80000953bb68 x19: ffffa618e0f18138 x18: 0000000000000001 [ 369.757968] x17: 0000000020000000 x16: 0000000000000002 x15: 0000000000000000 [ 369.758032] x14: 0000000000000000 x13: 284e4f5f4e524157 x12: 5f534b434f4c5f47 [ 369.758097] x11: 00000000ffffdfff x10: ffffa618e0c79f88 x9 : ffffa618de472484 [ 369.758162] x8 : 000000000002ffe8 x7 : c0000000ffffdfff x6 : 00000000000affa8 [ 369.758227] x5 : 0000000000001fff x4 : 0000000000000000 x3 : 0000000000000027 [ 369.758292] x2 : 0000000000000001 x1 : ffff17fdc087c000 x0 : 0000000000000028 [ 369.758357] Call trace: [ 369.758383] __mutex_lock+0x348/0x424 [ 369.758420] mutex_lock_nested+0x4c/0x5c [ 369.758459] fb_deferred_io_mkwrite+0x78/0x1d8 [ 369.758507] do_page_mkwrite+0x5c/0x19c [ 369.758550] wp_page_shared+0x70/0x1a0 [ 369.758590] do_wp_page+0x3d0/0x510 [ 369.758628] handle_pte_fault+0x1c0/0x1e0 [ 369.758670] __handle_mm_fault+0x250/0x380 [ 369.758712] handle_mm_fault+0x17c/0x3a4 [ 369.758753] do_page_fault+0x158/0x530 [ 369.758792] do_mem_abort+0x50/0xa0 [ 369.758831] el0_da+0x78/0x19c [ 369.758864] el0t_64_sync_handler+0xbc/0x150 [ 369.758904] el0t_64_sync+0x190/0x194 [ 369.758942] irq event stamp: 11395 [ 369.758973] hardirqs last enabled at (11395): [<ffffa618de472554>] __up_console_sem+0x74/0x80 [ 369.759042] hardirqs last disabled at (11394): [<ffffa618de47254c>] __up_console_sem+0x6c/0x80 [ 369.760554] softirqs last enabled at (11392): [<ffffa618de330a74>] __do_softirq+0x4c4/0x6b8 [ 369.762060] softirqs last disabled at (11383): [<ffffa618de3c9124>] __irq_exit_rcu+0x104/0x214 [ 369.763564] ---[ end trace 0000000000000000 ]--- Fixes: d536540f304c ("drm/fb-helper: Add generic fbdev emulation .fb_probe function") Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20230121192418.2814955-4-javierm@redhat.com
2023-01-23drm/edid: add separate drm_edid_connector_add_modes()Jani Nikula
The original goal with drm_edid_connector_update() was to have a single call for updating the connector and adding probed modes, in this order, but that turned out to be problematic. Drivers that need to update the connector in the .detect() callback would end up updating the probed modes as well. Turns out the callback may be called so many times that the probed mode list fills up without bounds, and this is amplified by add_alternate_cea_modes() duplicating the CEA modes on every call, actually running out of memory on some machines. Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me. Go back to having separate drm_edid_connector_update() and drm_edid_connector_add_modes() calls. The former may be called from .detect(), .force(), or .get_modes(), but the latter only from .get_modes(). Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update the probed modes from the EDID property instead of the passed in EDID. This is mainly to enforce two things: 1) drm_edid_connector_update() must be called before drm_edid_connector_add_modes(). Display info and quirks are needed for parsing the modes, and we don't want to call update_display_info() again to ensure the info is available, like drm_add_edid_modes() does. 2) The same EDID is used for both updating the connector and adding the probed modes. Fortunately, the change is easy, because no driver has actually adopted drm_edid_connector_update(). Not even i915, and that's mainly because of the problem described above.

Currently there is no easy way for a drm driver to safely check and allow drm_vma_offset_node for a drm file just once. Allow drm drivers to call non-refcounted version of drm_vma_node_allow() so that a driver doesn't need to keep track of each drm_vma_node_allow() to call subsequent drm_vma_node_revoke() to prevent memory leak.

2023-01-19drm/edid: refactor CTA Y420CMDB parsingJani Nikula
Now that we have pre-parsed CTA VDB VICs stored in info->vics, leverage that to simplify CTA Y420CMDB parsing. Move updating the y420_cmdb_modes bitmap to the display info parsing stage, instead of updating it during add modes. This allows us to drop the intermediate y420_cmdb_map from display info, and replace it with a local variable. This is prerequisite work for overall better separation of the two parsing steps (updating display info and adding modes).

It also states that one parameter (i.e. one byte) shall be sent/received for 8 bit wide values, and two parameters shall be used for values that are between 9 and 16 bits wide. Add new functions to properly handle 16-bit brightness in big endian, since the two 8- and 16-bit cases are distinct from each other.

2023-01-12drm: document better that drivers shouldn't use drm_minor directlyDaniel Vetter
The documentation for struct drm_minor already states this, but that's not always that easy to find. Also due to historical reasons we still have the minor-centric interfaces (like drm_debugfs_create_files), but since this is now getting fixed we can put a few more pointers in place as to how this should be done ideally. Note that debugfs isn't there yet for all cases (debugfs files on kms objects like crtc/connector aren't supported, neither debugfs files with full fops), so the debugfs side of this is still rather aspirational and more for new users than converting everything existing. todo.rst covers the additional work needed already. Motivated by some discussion with Rodrigo on irc about how drm/xe should lay out its sysfs interfaces. v2: Make the debugfs situation clearer in the commit message, but don't elaborate more in the actual kerneldoc to avoid distracting from the main message around sysfs (Jani) Also fix some typos.

2023-01-07drm/mipi-dsi: Add a mipi_dsi_dcs_write_seq() macroJavier Martinez Canillas
Many panel drivers define dsi_dcs_write_seq() and dsi_generic_write_seq() macros to send DCS commands and generic write packets respectively, with the payload specified as a list of parameters instead of using arrays. There's already a macro for the former, introduced by commit 2a9e9daf75231 ("drm/mipi-dsi: Introduce mipi_dsi_dcs_write_seq macro") so drivers can be changed to use that. But there isn't one yet for the latter, let's add it.

2023-01-05drm/probe-helper: enable and disable HPD on connectorsDmitry Baryshkov
Introduce two drm_connector_helper_funcs: enable_hpd() and disable_hpd(). They are called by drm_kms_helper_poll_enable() and drm_kms_helper_poll_disable() (and thus drm_kms_helper_poll_init() and drm_kms_helper_poll_fini()) respectively. This allows DRM drivers to rely on drm_kms_helper_poll for enabling and disabling HPD detection rather than doing that manually.

2023-01-03drm/format-helper: Simplify drm_fb_build_fourcc_list()Thomas Zimmermann
The DRM helper drm_fb_build_fourcc_list() creates a list of color formats for primary planes of the generic drivers. Simplify the helper: - It used to mix and filter native and emulated formats as provided by the driver. Now the only emulated format is XRGB8888, which is required as fallback by legacy software. Drop support for emulating any other formats. - Also convert alpha formats to their non-alpha counterparts. Generic drivers don't support primary planes with alpha formats and some DTs incorrectly advertise alpha channels for non-alpha hardware. So only export non-alpha formats for primary planes. With the simplified helper, scrap format lists of the affected generic drivers. All they need is the firmware buffer's native format, from which the helper creates the list of color formats.
