fbcon: Add option to enable legacy hardware acceleration
Add a config option CONFIG_FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION to enable bitblt and fillrect hardware acceleration in the framebuffer console. If disabled, such acceleration will not be used, even if it is supported by the graphics hardware driver. If you plan to use DRM as your main graphics output system, you should disable this option since it will prevent compiling in code which isn't used later on when DRM takes over. For all other configurations, e.g. if none of your graphic cards support DRM (yet), DRM isn't available for your architecture, or you can't be sure that the graphic card in the target system will support DRM, you most likely want to enable this option. In the non-accelerated case (e.g. when DRM is used), the inlined fb_scrollmode() function is hardcoded to return SCROLL_REDRAW and as such the compiler is able to optimize much unneccesary code away. In this v3 patch version I additionally changed the GETVYRES() and GETVXRES() macros to take a pointer to the fbcon_display struct. This fixes the build when console rotation is enabled and helps the compiler again to optimize out code.

video: hyperv_fb: Fix validation of screen resolution
In the WIN10 version of the Synthetic Video protocol with Hyper-V,
Hyper-V reports a list of supported resolutions as part of the protocol
negotiation. The driver calculates the maximum width and height from
the list of resolutions, and uses those maximums to validate any screen
resolution specified in the video= option on the kernel boot line.
This method of validation is incorrect. For example, the list of
supported resolutions could contain 1600x1200 and 1920x1080, both of
which fit in an 8 Mbyte frame buffer. But calculating the max width
and height yields 1920 and 1200, and 1920x1200 resolution does not fit
in an 8 Mbyte frame buffer. Unfortunately, this resolution is accepted,
causing a kernel fault when the driver accesses memory outside the
frame buffer.
Instead, validate the specified screen resolution by calculating
its size, and comparing against the frame buffer size. Delete the
code for calculating the max width and height from the list of
resolutions, since these max values have no use. Also add the
frame buffer size to the info message to aid in understanding why
a resolution might be rejected.

video: vga16fb: Only probe for EGA and VGA 16 color graphic cards
The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit |

backlight: qcom-wled: Respect enabled-strings in set_brightness
The hardware is capable of controlling any non-contiguous sequence of LEDs specified in the DT using qcom,enabled-strings as u32 array, and this also follows from the DT-bindings documentation. The numbers specified in this array represent indices of the LED strings that are to be enabled and disabled. Its value is appropriately used to setup and enable string modules, but completely disregarded in the set_brightness paths which only iterate over the number of strings linearly. Take an example where only string 2 is enabled with qcom,enabled_strings=<2>: this string is appropriately enabled but subsequent brightness changes would have only touched the zero'th brightness register because num_strings is 1 here. This is simply addressed by looking up the string for this index in the enabled_strings array just like the other codepaths that iterate over num_strings. Likewise enabled_strings is now also used in the autodetection path for consistent behaviour: when a list of strings is specified in DT only those strings will be probed for autodetection, analogous to how the number of strings that need to be probed is already bound by qcom,num-strings. After all autodetection uses the set_brightness helpers to set an initial value, which could otherwise end up changing brightness on a different set of strings. Fixes: |

Only WLED 3 sets a sensible default that allows operating this driver with just qcom,num-strings in the DT; WLED 4 and 5 require qcom,enabled-strings to be provided otherwise enabled_strings remains zero-initialized, resulting in every string-specific register write (currently only the setup and config functions, brightness follows in a future patch) to only configure the zero'th string multiple times.

backlight: qcom-wled: Remove unnecessary 4th default string in WLED3
The previous commit improves num_strings parsing to not go over the maximum of 3 strings for WLED3 anymore. Likewise this default index for a hypothetical 4th string is invalid and could access registers that are not mapped to the desired purpose. Removing this value gets rid of undesired confusion and avoids the possibility of accessing registers at this offset even if the 4th array element is used by accident.

backlight: qcom-wled: Override default length with qcom,enabled-strings
The length of qcom,enabled-strings as property array is enough to
determine the number of strings to be enabled, without needing to set
qcom,num-strings to override the default number of strings when less
than the default (which is also the maximum) is provided in DT.
This also introduces an extra warning when qcom,num-strings is set,
denoting that it is not necessary to set both anymore. It is usually
more concise to set just qcom,num-length when a zero-based, contiguous
range of strings is needed (the majority of the cases), or to only set
qcom,enabled-strings when a specific set of indices is desired.

backlight: qcom-wled: Fix off-by-one maximum with default num_strings
When not specifying num-strings in the DT the default is used, but +1 is
added to it which turns WLED3 into 4 and WLED4/5 into 5 strings instead
of 3 and 4 respectively, causing out-of-bounds reads and register
read/writes. This +1 exists for a deficiency in the DT parsing code,
and is simply omitted entirely - solving this oob issue - by parsing the
property separately much like qcom,enabled-strings.
This also enables more stringent checks on the maximum value when
qcom,enabled-strings is provided in the DT, by parsing num-strings after
enabled-strings to allow it to check against (and in a subsequent patch
override) the length of enabled-strings: it is invalid to set
num-strings higher than that.
The DT currently utilizes it to get around an incorrect fixed read of
four elements from that array (has been addressed in a prior patch) by
setting a lower num-strings where desired.

of_property_read_u32_array takes the number of elements to read as last
argument. This does not always need to be 4 (sizeof(u32)) but should
instead be the size of the array in DT as read just above with
of_property_count_elems_of_size.
To not make such an error go unnoticed again the driver now bails
accordingly when of_property_read_u32_array returns an error.
Surprisingly the indentation of newlined arguments is lining up again

drm: Move nomodeset kernel parameter to the DRM subsystem
The "nomodeset" kernel cmdline parameter is handled by the vgacon driver but the exported vgacon_text_force() symbol is only used by DRM drivers. It makes much more sense for the parameter logic to be in the subsystem of the drivers that are making use of it. Let's move the vgacon_text_force() function and related logic to the DRM subsystem. While doing that, rename it to drm_firmware_drivers_only() and make it return true if "nomodeset" was used and false otherwise. This is a better description of the condition that the drivers are testing for.

xen: add "not_essential" flag to struct xenbus_driver
When booting the xenbus driver will wait for PV devices to have connected to their backends before continuing. The timeout is different between essential and non-essential devices. Non-essential devices are identified by their nodenames directly in the xenbus driver, which requires to update this list in case a new device type being non-essential is added (this was missed for several types in the past). In order to avoid this problem, add a "not_essential" flag to struct xenbus_driver which can be set to "true" by the respective frontend. Set this flag for the frontends currently regarded to be not essential (vkbs and vfb) and use it for testing in the xenbus driver.

fbdev: Prevent probing generic drivers if a FB is already registered
The efifb and simplefb drivers just render to a pre-allocated frame buffer and rely on the display hardware being initialized before the kernel boots. But if another driver already probed correctly and registered a fbdev, the generic drivers shouldn't be probed since an actual driver for the display hardware is already present. This is more likely to occur after commit |

Fix the following fallthrough warnings: drivers/video/fbdev/omap/omapfb_main.c:1558:2: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough] case 0: ^ drivers/video/fbdev/omap/omapfb_main.c:1558:2: note: insert 'break;' to avoid fall-through case 0: ^ break; 1 warning generated. This helps with the ongoing efforts to globally enable -Wimplicit-fallthrough for Clang.

fbdev: fbmem: Fix double free of 'fb_info->pixmap.addr'
savagefb and some other drivers call kfree to free 'info->pixmap.addr' even after calling unregister_framebuffer, which may cause double free. Fix this by setting 'fb_info->pixmap.addr' to NULL after kfree in unregister_framebuffer. The following log reveals it: [ 37.318872] BUG: KASAN: double-free or invalid-free in kfree+0x13e/0x290 [ 37.319369] [ 37.320803] Call Trace: [ 37.320992] dump_stack_lvl+0xa8/0xd1 [ 37.321274] print_address_description+0x87/0x3b0 [ 37.321632] ? kfree+0x13e/0x290 [ 37.321879] ? kfree+0x13e/0x290 [ 37.322126] ? kfree+0x13e/0x290 [ 37.322374] kasan_report_invalid_free+0x58/0x90 [ 37.322724] ____kasan_slab_free+0x123/0x140 [ 37.323049] __kasan_slab_free+0x11/0x20 [ 37.323347] slab_free_freelist_hook+0x81/0x150 [ 37.323689] ? savagefb_remove+0xa1/0xc0 [savagefb] [ 37.324066] kfree+0x13e/0x290 [ 37.324304] savagefb_remove+0xa1/0xc0 [savagefb] [ 37.324655] pci_device_remove+0xa9/0x250 [ 37.324959] ? pci_device_probe+0x7d0/0x7d0 [ 37.325273] device_release_driver_internal+0x4f7/0x7a0 [ 37.325666] driver_detach+0x1e8/0x2c0 [ 37.325952] bus_remove_driver+0x134/0x290 [ 37.326262] ? sysfs_remove_groups+0x97/0xb0 [ 37.326584] driver_unregister+0x77/0xa0 [ 37.326883] pci_unregister_driver+0x2c/0x1c0 [ 37.336124] [ 37.336245] Allocated by task 5465: [ 37.336507] ____kasan_kmalloc+0xb5/0xe0 [ 37.336801] __kasan_kmalloc+0x9/0x10 [ 37.337069] kmem_cache_alloc_trace+0x12b/0x220 [ 37.337405] register_framebuffer+0x3f3/0xa00 [ 37.337731] foo_register_framebuffer+0x3b/0x50 [savagefb] [ 37.338136] [ 37.338255] Freed by task 5475: [ 37.338492] kasan_set_track+0x3d/0x70 [ 37.338774] kasan_set_free_info+0x23/0x40 [ 37.339081] ____kasan_slab_free+0x10b/0x140 [ 37.339399] __kasan_slab_free+0x11/0x20 [ 37.339694] slab_free_freelist_hook+0x81/0x150 [ 37.340034] kfree+0x13e/0x290 [ 37.340267] do_unregister_framebuffer+0x21c/0x3d0 [ 37.340624] unregister_framebuffer+0x23/0x40 [ 37.340950] savagefb_remove+0x45/0xc0 [savagefb] [ 37.341302] pci_device_remove+0xa9/0x250 [ 37.341603] device_release_driver_internal+0x4f7/0x7a0 [ 37.341990] driver_detach+0x1e8/0x2c0 [ 37.342272] bus_remove_driver+0x134/0x290 [ 37.342577] driver_unregister+0x77/0xa0 [ 37.342873] pci_unregister_driver+0x2c/0x1c0 [ 37.343196] cleanup_module+0x15/0x1c [savagefb] [ 37.343543] __se_sys_delete_module+0x398/0x490 [ 37.343881] __x64_sys_delete_module+0x56/0x60 [ 37.344221] do_syscall_64+0x4d/0xc0 [ 37.344492] entry_SYSCALL_64_after_hwframe+0x44/0xae Signed-off-by: Zheyu Ma <zheyuma97@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/1633848148-29747-1-git-send-email-zheyuma97@gmail.com |
