From caa478af48121ea21a8a4d6fe8a1bd467016adba Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Wed, 25 Sep 2019 15:11:23 +0200 Subject: drm/ttm: Convert vm callbacks to helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The default TTM fault handler may not be completely sufficient (vmwgfx needs to do some bookkeeping, control the write protectionand also needs to restrict the number of prefaults). Also make it possible replicate ttm_bo_vm_reserve() functionality for, for example, mkwrite handlers. So turn the TTM vm code into helpers: ttm_bo_vm_fault_reserved(), ttm_bo_vm_open(), ttm_bo_vm_close() and ttm_bo_vm_reserve(). Also provide a default TTM fault handler for other drivers to use.

Clean up the drm top level directory, Kconfig and Makefile by making ati_pcigart.[ch] part of r128. Drop the CONFIG_DRM_ATI_PCIGART config option made redundant by the change.

Aside: The ->mmap/munmap hooks have a bit a confusing name, they don't do userspace mmaps, but a kernel vmap. I think most places use vmap for this, except ttm, which uses kmap for vmap for added confusion. mmap seems entirely for userspace mappings set up through mmap(2) syscall.

Reality is that they simply never caught on, and nowadays everyone who needs plenty of buffers will run in 64bit mode anyway. Also update the docs in this area to adjust them to reality. The actual hooks in dma_buf_ops will be removed once all the implementations are gone.

The controller would enter a reconnect state and as long as the LLDD resumed within the reconnect timeout, the controller would resume. But if a namespace on the controller is the root device, allowing the driver to unload can be problematic. To reload the driver, it may require new io to the boot device, and as it's no longer connected we get into a catch-22 that eventually fails, and the system locks up. Fix this issue by taking a module reference for every connected controller (which is what the core layer did to the transport module). Reference is cleared when the controller is removed.

Or at least, that's the current running theory. The precise behavior appears to be that when the source device gets reset unexpectedly, the hub begins reporting an available_pbn value of 0 for all of its ports. This is a bit inconsistent with the our theory, since this seems to happen even if previously set PBN allocations should have resulted in a non-zero available_pbn value. So, it's possible that something else may be going on here. Strangely though, sending a CLEAR_PAYLOAD_ID_TABLE broadcast request when initializing the MST topology seems to bring things into working order and make available_pbn work again. Since this is a pretty safe solution, let's go ahead and implement it.

But before we can do that we must provide a drm_bridge_chain_get_first_bridge() bridge helper and patch all drivers and core helpers to use it instead of directly accessing encoder->bridge. Note that we still have 2 drivers (VC4 and Exynos) manipulating the encoder->bridge field directly because they need to cut the bridge chain in order to control the enable/disable sequence. This is definitely not something we want to encourage, so let's keep those 2 oddities around until we find a better solution.

Update the drm_panel infrastructure to support this to simplify the drivers. With this the panel driver just needs to add the following to the probe() function: err = drm_panel_of_backlight(panel); if (err) return err; Then drm_panel will handle all the rest. There is one caveat with the backlight support. If drm_panel_(enable|disable) are called multiple times in a row then backlight_(enable|disable) will be called multiple times. The above will happen when a panel drivers unconditionally calls drm_panel_disable() in their shutdown() function, whan the panel is already disabled and then shutdown() is called. Reading the backlight code it seems safe to call the backlight_(enable|disable) several times. v3: - Improve comments, fix grammar (Laurent) - Do not fail in drm_panel_of_backlight() if no DT support (Laurent) - Log if backlight_(enable|disable) fails (Laurent) - Improve drm_panel_of_backlight() docs - Updated changelog with backlight analysis (triggered by Laurent) v2: - Drop test of CONFIG_DRM_PANEL in header-file (Laurent) - do not enable backlight if ->enable() returns an error Signed-off-by: Sam Ravnborg Reviewed-by: Laurent Pinchart Cc: Thierry Reding Cc: Laurent Pinchart Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Sean Paul Cc: David Airlie Cc: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20191207140353.23967-3-sam@ravnborg.org --- drivers/gpu/drm/drm_panel.c | 62 +++++++++++++++++++++++++++++++++++++++++++-- include/drm/drm_panel.h | 25 ++++++++++++++++++ 2 files changed, 85 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/drivers/gpu/drm/drm_panel.c b/drivers/gpu/drm/drm_panel.c index 4ab7229fb22b..a5e4084eb0e3 100644 --- a/drivers/gpu/drm/drm_panel.c +++ b/drivers/gpu/drm/drm_panel.c @@ -21,11 +21,13 @@ * DEALINGS IN THE SOFTWARE. */ +#include #include #include #include #include +#include static DEFINE_MUTEX(panel_lock); static LIST_HEAD(panel_list); @@ -196,11 +198,21 @@ EXPORT_SYMBOL(drm_panel_unprepare); */ int drm_panel_enable(struct drm_panel *panel) { + int ret; + if (!panel) return -EINVAL; - if (panel->funcs && panel->funcs->enable) - return panel->funcs->enable(panel); + if (panel->funcs && panel->funcs->enable) { + ret = panel->funcs->enable(panel); + if (ret < 0) + return ret; + } + + ret = backlight_enable(panel->backlight); + if (ret < 0) + DRM_DEV_INFO(panel->dev, "failed to enable backlight: %d\n", + ret); return 0; } @@ -218,9 +230,16 @@ EXPORT_SYMBOL(drm_panel_enable); */ int drm_panel_disable(struct drm_panel *panel) { + int ret; + if (!panel) return -EINVAL; + ret = backlight_disable(panel->backlight); + if (ret < 0) + DRM_DEV_INFO(panel->dev, "failed to disable backlight: %d\n", + ret); + if (panel->funcs && panel->funcs->disable) return panel->funcs->disable(panel); @@ -289,6 +308,45 @@ struct drm_panel *of_drm_find_panel(const struct device_node *np) EXPORT_SYMBOL(of_drm_find_panel); #endif +#ifdef CONFIG_BACKLIGHT_CLASS_DEVICE +/** + * drm_panel_of_backlight - use backlight device node for backlight + * @panel: DRM panel + * + * Use this function to enable backlight handling if your panel + * uses device tree and has a backlight phandle. + * + * When the panel is enabled backlight will be enabled after a + * successful call to &drm_panel_funcs.enable() + * + * When the panel is disabled backlight will be disabled before the + * call to &drm_panel_funcs.disable(). + * + * A typical implementation for a panel driver supporting device tree + * will call this function at probe time.

charset=UTF-8 Content-Transfer-Encoding: 8bit To facilitate moving connector creation to display drivers, decouple the drm_connector from drm_panel. This patch adds a connector argument to drm_panel_get_modes(). All users of drm_panel_get_modes() already had the connector available, so updating users was trivial. With this patch drm_panel no longer keeps a reference to the drm_connector.

charset=UTF-8 Content-Transfer-Encoding: 8bit The panel drivers used drm_panel.drm for two purposes: 1) Argument to drm_mode_duplicate() 2) drm->dev was used in error messages The first usage is replaced with drm_connector.dev - drm_connector is already connected to a drm_device and we have a valid connector The second usage is replaced with drm_panel.dev - this makes drivers more consistent in their dev argument used for dev_err() and friends With these replacements there are no more uses of drm_panel.drm, so it is removed from struct drm_panel. With this change drm_panel_attach() and drm_panel_detach() no longer have any use as they are empty functions. v2: - editorial correction in changelog (Laurent) Signed-off-by: Sam Ravnborg Reviewed-by: Laurent Pinchart Reviewed-by: Linus Walleij Cc: Thierry Reding Cc: Laurent Pinchart Cc: Sam Ravnborg Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: David Airlie Cc: Daniel Vetter Cc: Linus Walleij Cc: Jagan Teki Cc: Stefan Mavrodiev Cc: Robert Chiras Cc: "Guido Günther" Cc: Purism Kernel Team Link: https://patchwork.freedesktop.org/patch/msgid/20191207140353.23967-8-sam@ravnborg.org --- drivers/gpu/drm/drm_panel.c | 6 ------ drivers/gpu/drm/panel/panel-arm-versatile.c | 2 +- drivers/gpu/drm/panel/panel-feiyang-fy07024di26a30d.c | 2 +- drivers/gpu/drm/panel/panel-ilitek-ili9322.c | 15 ++++++++------- drivers/gpu/drm/panel/panel-ilitek-ili9881c.c | 2 +- drivers/gpu/drm/panel/panel-innolux-p079zca.c | 6 +++--- drivers/gpu/drm/panel/panel-jdi-lt070me05000.c | 2 +- drivers/gpu/drm/panel/panel-kingdisplay-kd097d04.c | 6 +++--- drivers/gpu/drm/panel/panel-lg-lb035q02.c | 2 +- drivers/gpu/drm/panel/panel-lg-lg4573.c | 4 ++-- drivers/gpu/drm/panel/panel-lvds.c | 2 +- drivers/gpu/drm/panel/panel-nec-nl8048hl11.c | 2 +- drivers/gpu/drm/panel/panel-novatek-nt39016.c | 2 +- drivers/gpu/drm/panel/panel-olimex-lcd-olinuxino.c | 5 ++--- drivers/gpu/drm/panel/panel-orisetech-otm8009a.c | 2 +- drivers/gpu/drm/panel/panel-osd-osd101t2587-53ts.c | 4 ++-- drivers/gpu/drm/panel/panel-panasonic-vvx10f034n00.c | 8 ++++---- drivers/gpu/drm/panel/panel-raspberrypi-touchscreen.c | 5 ++--- drivers/gpu/drm/panel/panel-raydium-rm67191.c | 2 +- drivers/gpu/drm/panel/panel-raydium-rm68200.c | 2 +- drivers/gpu/drm/panel/panel-rocktech-jh057n00900.c | 2 +- drivers/gpu/drm/panel/panel-ronbo-rb070d30.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6d16d0.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6e3ha2.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6e63j0x03.c | 2 +- drivers/gpu/drm/panel/panel-samsung-s6e63m0.c | 2 +- drivers/gpu/drm/panel/panel-seiko-43wvf1g.c | 9 ++++----- drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c | 4 ++-- drivers/gpu/drm/panel/panel-sharp-ls037v7dw01.c | 2 +- drivers/gpu/drm/panel/panel-sharp-ls043t1le01.c | 8 ++++---- drivers/gpu/drm/panel/panel-simple.c | 16 +++++++--------- drivers/gpu/drm/panel/panel-sitronix-st7701.c | 2 +- drivers/gpu/drm/panel/panel-sitronix-st7789v.c | 4 ++-- drivers/gpu/drm/panel/panel-sony-acx565akm.c | 2 +- drivers/gpu/drm/panel/panel-tpo-td028ttec1.c | 2 +- drivers/gpu/drm/panel/panel-tpo-td043mtea1.c | 2 +- drivers/gpu/drm/panel/panel-tpo-tpg110.c | 2 +- include/drm/drm_panel.h | 7 ------- 38 files changed, 68 insertions(+), 85 deletions(-) (limited to 'include') diff --git a/drivers/gpu/drm/drm_panel.c b/drivers/gpu/drm/drm_panel.c index f6a745949da8..03395ad4d907 100644 --- a/drivers/gpu/drm/drm_panel.c +++ b/drivers/gpu/drm/drm_panel.c @@ -114,11 +114,6 @@ EXPORT_SYMBOL(drm_panel_remove);

Davis" Date: Tue, 3 Dec 2019 17:26:37 +0000 Subject: dma-buf: Add dma-buf heaps framework This framework allows a unified userspace interface for dma-buf exporters, allowing userland to allocate specific types of memory for use in dma-buf sharing. Each heap is given its own device node, which a user can allocate a dma-buf fd from using the DMA_HEAP_IOC_ALLOC. This code is an evoluiton of the Android ION implementation, and a big thanks is due to its authors/maintainers over time for their effort: Rebecca Schultz Zavin, Colin Cross, Benjamin Gaignard, Laura Abbott, and many other contributors!

Switch this over to use GPIO descriptors and delete the custom platform data. We create three new static locals in the tc35876x bridge code but it is hardly any worse than the I2C client static local already there: I tried first to move it to the DRM driver state container but there are workarounds for probe order in the code so I just stayed off it, as the result is unpredictable. People wanting to do a more throrugh and proper cleanup of the GMA500 driver can work on top of this, I can't solve much more since I don't have access to the hardware, I can only attempt to tidy up my GPIO corner.

Either for testing and for special cases, e.g. a kiosk like setup which uses a TV mounted in portrait mode. Users can already specify a "rotate" option through a video= kernel cmdline option. But that only supports 0/180 degrees (see drm_client_modeset TODO) and only works for in kernel modeset clients, not for userspace kms users. The "panel-orientation" connector property OTOH does support 90/270 degrees as it leaves dealing with the rotation up to userspace and this does work for userspace kms clients (at least those which support this property).

These would be preferred over the drm printk and struct device based macros in drm code, where possible. We have existing drm specific struct device based logging functions, but they are too verbose to use for two main reasons: * The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS(). * The use of struct device over struct drm_device is too generic for most users, leading to an extra dereference. For example: DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n"); vs. drm_dbg_kms(drm, "Hello, world\n"); It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be less readable than lowercase. Some names are changed from old DRM names to be based on the core kernel logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG -> dbg. Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use (DRM_DEBUG is used widely in drivers though it's supposed to be a core debugging category), they are named as drm_dbg_core and drm_dbg, respectively. The drm_err and _once/_ratelimited variants no longer include the function name in order to be able to use the core device based logging macros. Arguably this is not a significant change; error messages should not be so common to be only distinguishable by the function name. Ratelimited debug logging macros are to be added later.

The device tree can be used to fully describe dual-link LVDS connections between encoders and bridges/panels. The sink of an LVDS dual-link connection is made of two ports, the corresponding OF graph port nodes can be marked with either dual-lvds-even-pixels or dual-lvds-odd-pixels, and that fully describes an LVDS dual-link connection, including pixel order. drm_of_lvds_get_dual_link_pixel_order is a new helper added by this patch, given the source port nodes it returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source port nodes belong to an LVDS dual-link connection, with even pixels expected to be generated from the first port, and odd pixels expected to be generated from the second port. If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS, odd pixels are expected to be generated from the first port, and even pixels from the other port.

These bus configurations are exposed through the drm_bus_cfg struct which encodes the configuration of a physical bus between two components in an output pipeline, usually between two bridges, an encoder and a bridge, or a bridge and a connector. The bus configuration is stored in drm_bridge_state separately for the input and output buses, as seen from the point of view of each bridge. The bus configuration of a bridge output is usually identical to the configuration of the next bridge's input, but may differ if the signals are modified between the two bridges, for instance by an inverter on the board. The input and output configurations of a bridge may differ if the bridge modifies the signals internally, for instance by performing format conversion, or*modifying signals polarities. Bus format negotiation is automated by the core, drivers just have to implement the ->atomic_get_{output,input}_bus_fmts() hooks if they want to take part to this negotiation. Negotiation happens in reverse order, starting from the last element of the chain (the one directly connected to the display) up to the first element of the chain (the one connected to the encoder). During this negotiation all supported formats are tested until we find one that works, meaning that the formats array should be in decreasing preference order (assuming the driver has a preference order). Note that the bus format negotiation works even if some elements in the chain don't implement the ->atomic_get_{output,input}_bus_fmts() hooks. In that case, the core advertises only MEDIA_BUS_FMT_FIXED and lets the previous bridge element decide what to do (most of the time, bridge drivers will pick a default bus format or extract this piece of information from somewhere else, like a FW property).

There's only one correct value for the BO device anyway, which is the one stored in the DRM device. So remove struct ttm_bo_device from the VRAM-helper interface and use the device's VRAM manager unconditionally. The GEM initializer function fails if the VRAM manager has not been initialized.
