video/aperture: Provide a VGA helper for gma500 and internal use The hardware for gma500 is different from the rest, as it uses stolen framebuffer memory that is not available via PCI BAR. The regular PCI removal helper cannot detect the framebuffer, while the non-PCI helper misses possible conflicting VGA devices (i.e., a framebuffer or text console). Gma500 therefore calls both helpers to catch all cases. It's confusing as it implies that there's something about the PCI device that requires ownership management. The relationship between the PCI device and the VGA devices is non-obvious. At worst, readers might assume that calling two functions for clearing aperture ownership is a bug in the driver. Hence, move the PCI removal helper's code for VGA functionality into a separate function and call this function from gma500. Documents the purpose of each call to aperture helpers. The change contains comments and example code form the discussion at [1]. v5: * fix grammar in gma500 comment (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.kernel.org/project/dri-devel/patch/20230404201842.567344-1-daniel.vetter@ffwll.ch/ # 1 Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230406132109.32050-10-tzimmermann@suse.de

drm/gma500: Use drm_aperture_remove_conflicting_pci_framebuffers This one nukes all framebuffers, which is a bit much. In reality gma500 is igpu and never shipped with anything discrete, so there should not be any difference. v2: Unfortunately the framebuffer sits outside of the pci bars for gma500, and so only using the pci helpers won't be enough. Otoh if we only use non-pci helper, then we don't get the vga handling, and subsequent refactoring to untangle these special cases won't work. It's not pretty, but the simplest fix (since gma500 really is the only quirky pci driver like this we have) is to just have both calls. v4: - fix Daniel's S-o-b address v5: - add back an S-o-b tag with Daniel's Intel address Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230406132109.32050-2-tzimmermann@suse.de

drm/gma500: Implement client-based fbdev emulation Implement fbdevemulation on top of struct drm_client and its helpers. This ad-hoc interfaces for restoring and closing fbdev emulation with per-client callback for hotplugging, restoring and unregistering. A single function, psb_fbdev_setup(), starts fbdev emulation after the DRM device has been registered. Hence, fbdev acts like a regular DRM client. The setup call only prepares the fbdev emulation. It then implements connector hotplugging. The first successful hotplug event initializes fbdev emulation. Unregistering depends on the hotplugging. Fully initialized emulation is cleaned up through drm_fb_helper_unregister_info() and fb_destroy. For prepared-only setups, unregistering unprepares the emulation and releases all resources. In both cases, fbdev emulation will be cleaned up. v2: * declare empty setup function as 'static inline' (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230313151610.14367-7-tzimmermann@suse.de

drm/gma500: Call acpi_video_register_backlight() On machines without an Intel video opregion the acpi_video driver immediately probes the ACPI video bus and used to also immediately register acpi_video# backlight devices when supported. Once the drm/kms driver then loaded later and possibly registered a native backlight device then the drivers/acpi/video_detect.c code unregistered the acpi_video0 device to avoid there being 2 backlight devices (when acpi_video_get_backlight_type()==native). This means that userspace used to briefly see 2 devices and the disappearing of acpi_video0 after a brief time confuses the systemd backlight level save/restore code, see e.g.: https://bbs.archlinux.org/viewtopic.php?id=269920 To fix this the ACPI video code has been modified to make backlight class device registration a separate step, relying on the drm/kms driver to ask for the acpi_video backlight registration after it is done setting up its native backlight device. Add a call to the new acpi_video_register_backlight() function after setting up the gma500's native backlight, so that the acpi_video backlight device gets registered on systems where the gma500's native backlight device is not registered.

drm/gma500: Refactor backlight support (v2) Refactor backlight support so that the gma_backlight_enable() / gma_backlight_disable() / gma_backlight_set() functions used by the Opregion handle will also work if no backlight_device gets registered. This is a preparation patch for not registering the gma500's own backlight device when acpi_video should be used, since registering 2 backlight devices for a single display really is undesirable. Since the acpi-video interface often uses the OpRegion we need to keep the OpRegion functional even when dev_priv->backlight_device is NULL. As a result of this refactor the actual backlight_device_register() call is moved to the shared backlight.c code and all #ifdefs related to CONFIG_BACKLIGHT_CLASS_DEVICE are now also limited to backlight.c . No functional changes intended. This has been tested on a Packard Bell Dot SC (Intel Atom N2600, cedarview) and a Sony Vaio vpc-x11s1e (Intel N540, poulsbo) laptop. Changes in v2: - Fix unused variable warnings when CONFIG_BACKLIGHT is not selected by marking the 2 variables as __maybe_unused.

drm/gma500: Rewrite power management code Rewrite the power.c code. For some reason this was doing locking + refcounting + state (suspended or not) bookkeeping all by itself. But there is no reason for this, this is all taken care of by the runtime-pm core, through pm_runtime_get()/_put(). Besides this not being necessary the DIY code is also quite weird/ buggy in some places. E.g. power_begin() would manually do a resume when not resumed already and force_on=true, followed by a pm_runtime_get(), which will cause a call to gma_power_resume() to get scheduled which would redo the entire resume again. Which can all be replaced by a single pm_runtime_get_sync() call. Note that this is just a cleanup, this does not actually fix the (disabled through #if 0) runtime-pm support. It does now call pm_runtime_enable(), but only after doing a pm_runtime_get() at probe-time, so the device is never runtime suspended. Doing this permanent get() + enable() instead of not calling enable() at all is necessary for the pm_runtime_get_if_in_use() call in gma_power_begin() to work properly. Note this also removes the gma_power_is_on() call a check like this without actually holding a reference is always racy, so it is a bad idea (and therefor has no pm_runtime_foo() equivalent). The 2 code paths which were using gma_power_is_on() are actually both guaranteed to only run when the device is powered-on so the 2 checks can simply be dropped.

drm/gma500: Fix (vblank) IRQs not working after suspend/resume Fix gnome-shell (and other page-flip users) hanging after suspend/resume because of the gma500's IRQs not working. This fixes 2 problems with the IRQ handling: 1. gma_power_off() calls gma_irq_uninstall() which does a free_irq(), but gma_power_on() called gma_irq_preinstall() + gma_irq_postinstall() which do not call request_irq. Replace the pre- + post-install calls with gma_irq_install() which does prep + request + post. 2. After fixing 1. IRQs still do not work on a Packard Bell Dot SC (Intel Atom N2600, cedarview) netbook. Cederview uses MSI interrupts and it seems that the BIOS re-configures things back to normal APIC based interrupts during S3 suspend. There is some MSI PCI-config registers save/restore code which tries to deal with this, but on the Packard Bell Dot SC this is not sufficient to restore MSI IRQ functionality after a suspend/resume. Replace the PCI-config registers save/restore with pci_disable_msi() on suspend + pci_enable_msi() on resume. Fixing e.g. gnome-shell hanging.

Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver.

drm: Nuke ->vblank_disable_allowed This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.

drm: add driver->set_busid() callback One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.

drm: remove FASYNC support So I've stumbled over drm_fasync and wondered what it does. Digging that up is quite a story. First I've had to read up on what this does and ended up being rather bewildered why peopled loved signals so much back in the days that they've created SIGIO just for that ... Then I wondered how this ever works, and what that strange "No-op." comment right above it should mean. After all calling the core fasync helper is pretty obviously not a noop. After reading through the kernels FASYNC implementation I've noticed that signals are only sent out to the processes attached with FASYNC by calling kill_fasync. No merged drm driver has ever done that. After more digging I've found out that the only driver that ever used this is the so called GAMMA driver. I've frankly never heard of such a gpu brand ever before. Now FASYNC seems to not have been the only bad thing with that driver, since Dave Airlie removed it from the drm driver with prejudice: commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed Author: Dave Airlie <airlied@linux.ie> Date: Sun Aug 29 12:04:35 2004 +0000 Drop GAMMA DRM from a great height ... Long story short, the drm fasync support seems to be doing absolutely nothing. And the only user of it was never merged into the upstream kernel. And we don't need any fops->fasync callback since the fcntl implementation in the kernel already implements the noop case correctly. So stop this particular cargo-cult and rip it all out. v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers (somehow I've missed that one in staging). Also drop the reference in the drm DocBook. ARM compile-fail reported by Rob Clark. v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this patch here. v4: Actually git add ... tsk.

drm/gma500: move fbcon restore to lastclose Doing this within the fb->destroy callback leads to a locking nightmare. And all other drm drivers that restore the fbcon do it in lastclose, too. With this adjustments all fb->destroy callbacks optionally drop references to any gem objects used as backing storage, call drm_framebuffer_cleanup and then kfree the struct. Which nicely simplifies the locking for framebuffer unreferencing and freeing, since this doesn't require that we hold the mode_config lock. A slight exception is the vmwgfx surface backed framebuffer, it also calls drm_master_put and removes the object from a device-private framebuffer list. Both seem to have solid locking in place already. Conclusion is that now it is no longer required to hold the mode_config lock while freeing a framebuffer. v2: Drop the corresponding mutex_lock WARN check from drm_framebuffer_unreference. v3: Use just the mode_config lock not modeset_lock_all, due to patch reordering.

drm: move pci bus master enable into driver. The current enabling of bus mastering in the drm midlayer allows a large race condition under kexec. When a kexec'ed kernel re-enables bus mastering for the GPU, previously setup dma blocks may cause writes to random pieces of memory. On radeon the writeback mechanism can cause these sorts of issues. This patch doesn't fix the problem, but it moves the bus master enable under the individual drivers control so they can move enabling it until later in their load cycle and close the race. Fix for radeon kms driver will be in a follow-up patch. Signed-off-by: Dave Airlie <airlied@redhat.com>

gma500: frame buffer locking If we are the console then a printk can hit us with a spin lock held (and in fact the kernel will do its best to take the console printing lock). In that case we cannot politely sleep when synching after an accelerated op but must behave obnoxiously to be sure of getting the bits out.
