2022-10-14drm/i915: enable PS64 support for DG2Matthew Auld
It turns out that on production DG2/ATS HW we should have support for PS64. This feature allows to provide a 64K TLB hint at the PTE level, which is a lot more flexible than the current method of enabling 64K GTT pages for the entire page-table, since that leads to all kinds of annoying restrictions, as documented in: commit caa574ffc4aaf4f29b890223878c63e2e7772f62 Author: Matthew Auld <matthew.auld@intel.com> Date: Sat Feb 19 00:17:49 2022 +0530 drm/i915/uapi: document behaviour for DG2 64K support On discrete platforms like DG2, we need to support a minimum page size of 64K when dealing with device local-memory. This is quite tricky for various reasons, so try to document the new implicit uapi for this. With PS64, we can now drop the 2M GTT alignment restriction, and instead only require 64K or larger when dealing with lmem. We still use the compact-pt layout when possible, but only when we are certain that this doesn't interfere with userspace. Note that this is a change in uAPI behaviour, but hopefully shouldn't be a concern (IGT is at least able to autodetect the alignment), since we are only making the GTT alignment constraint less restrictive. Based on a patch from CQ Tang. v2: update the comment wrt scratch page v3: (Nirmoy) - Fix the selftest to actually use the random size, plus some comment improvements, also drop the rem stuff.

2022-10-14perf: Skip and warn on unknown format 'configN' attrsRob Herring
If the kernel exposes a new perf_event_attr field in a format attr, perf will return an error stating the specified PMU can't be found. For example, a format attr with 'config3:0-63' causes an error as config3 is unknown to perf. This causes a compatibility issue between a newer kernel with older perf tool. Before this change with a kernel adding 'config3' I get: $ perf record -e arm_spe// -- true event syntax error: 'arm_spe//' \___ Cannot find PMU `arm_spe'. Missing kernel support? Run 'perf list' for a list of valid events Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -e, --event <event> event selector. use 'perf list' to list available events After this change, I get: $ perf record -e arm_spe// -- true WARNING: 'arm_spe_0' format 'inv_event_filter' requires 'perf_event_attr::config3' which is not supported by this version of perf! [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.091 MB perf.data ] To support unknown configN formats, rework the YACC implementation to pass any config[0-9]+ format to perf_pmu__new_format() to handle with a warning.

Passed to xen_grant_dma_map_page() offset in the page can be > PAGE_SIZE even if the guest uses the same page granularity as Xen (4KB). Before current patch, if such case happened we ended up providing grants for the whole region in xen_grant_dma_map_page() which was really unnecessary. The more, we ended up not releasing all grants which represented that region in xen_grant_dma_unmap_page(). Current patch updates the code to be able to deal with such cases.

2022-10-14drm/i915: Fix simulated GPU reset wrt. encoder HW readoutImre Deak
The GPU reset involves a display suspend/resume sequence, but this is done without suspending/resuming the encoders. The encoder HW readout code during resume however assumes that the encoders were suspended/resumed, at least on TypeC platforms where the TC PHYs must be left in a disconnected state during encoder-suspend, and the PHY's TypeC mode must be initialized already during encoder-resume. Since the above issue occurs only in case the display recovery during GPU reset is simulated in CI tests (on new platforms w/o the GPU reset clobbering the display), this patch fixes the issue by simply restoring the saved display state in this case w/o doing a display HW state readout / sanitization first. This also fixes the WARN below introduced by commit a82796a2e332 ("drm/i915: Fix TypeC mode initialization during system resume") <4> [319.983309] ------------[ cut here ]------------ <4> [319.983313] i915 0000:00:02.0: drm_WARN_ON(dig_port->tc_link_refcount != 1) <4> [319.983341] WARNING: CPU: 10 PID: 268 at drivers/gpu/drm/i915/display/intel_tc.c:751 intel_tc_port_sanitize_mode+0x239/0x290 [i915] <4> [319.983407] Modules linked in: fuse snd_hda_codec_hdmi i915 x86_pkg_temp_thermal mei_hdcp coretemp wmi_bmof r8153_ecm cdc_ether kvm_intel usbnet r8152 mii kvm prime_numbers snd_hda_intel ttm snd_intel_dspcfg irqbypass drm_buddy e1000e crct10dif_pclmul snd_hda_codec crc32_pclmul drm_display_helper ptp snd_hwdep ghash_clmulni_intel snd_hda_core drm_kms_helper pps_core mei_me syscopyarea video i2c_i801 snd_pcm sysfillrect i2c_smbus sysimgblt mei fb_sys_fops intel_lpss_pci wmi <4> [319.983483] CPU: 10 PID: 268 Comm: kworker/10:1H Not tainted 6.0.0-rc7-CI_DRM_12200-g394e575b57e9+ #1 <4> [319.983486] Hardware name: Intel Corporation Alder Lake Client Platform/AlderLake-P LP5 RVP, BIOS ADLPFWI1.R00.2313.A00.2107301001 07/30/2021 <4> [319.983488] Workqueue: events_highpri heartbeat [i915] <4> [319.983536] RIP: 0010:intel_tc_port_sanitize_mode+0x239/0x290 [i915] <4> [319.983600] Code: 85 d2 75 03 48 8b 17 48 89 14 24 e8 e1 dc 2d e1 48 8b 14 24 48 c7 c1 f8 db 5b a0 48 c7 c7 3e 3c 5e a0 48 89 c6 e8 45 d7 66 e1 <0f> 0b e9 20 fe ff ff 0f 0b 49 c7 c0 8b 3c 5e a0 e9 9e fe ff ff 48 <4> [319.983601] RSP: 0018:ffffc90001617a30 EFLAGS: 00010286 <4> [319.983604] RAX: 0000000000000000 RBX: ffff88811f9d2000 RCX: 0000000000000001 <4> [319.983606] RDX: 0000000080000001 RSI: ffffffff8231e8cd RDI: 00000000ffffffff <4> [319.983607] RBP: ffff888121e98000 R08: 0000000000000000 R09: c0000000ffffc134 <4> [319.983608] R10: 00000000000d6078 R11: ffffc900016178c8 R12: ffff88811f9d3838 <4> [319.983609] R13: ffff88811f9d397d R14: ffff888121e98000 R15: 0000000000000000 <4> [319.983611] FS: 0000000000000000(0000) GS:ffff8882a7300000(0000) knlGS:0000000000000000 <4> [319.983612] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4> [319.983613] CR2: 00007fe7397f1e18 CR3: 0000000006612003 CR4: 0000000000770ee0 <4> [319.983615] PKRU: 55555554 <4> [319.983616] Call Trace: <4> [319.983617] <TASK> <4> [319.983621] intel_ddi_sync_state+0x3f/0x90 [i915] <4> [319.983698] intel_modeset_setup_hw_state+0x3a3/0x1440 [i915] <4> [319.983777] ? intel_gt_reset_global+0xeb/0x160 [i915] <4> [319.983839] ? __intel_display_resume+0x15/0xe0 [i915] <4> [319.983909] __intel_display_resume+0x15/0xe0 [i915] <4> [319.983979] intel_display_finish_reset+0x58/0x130 [i915] <4> [319.984048] intel_gt_reset_global+0xf3/0x160 [i915] <4> [319.984107] ? intel_reset_guc.cold.62+0x5d/0x5d [i915] <4> [319.984189] ? 0xffffffff81000000 <4> [319.984192] ? queue_work_node+0x90/0x90 <4> [319.984202] intel_gt_handle_error+0x2c2/0x410 [i915] <4> [319.984267] ? _raw_spin_unlock_irqrestore+0x54/0x70 <4> [319.984271] ? lockdep_hardirqs_on+0xbf/0x140 <4> [319.984276] ? intel_guc_find_hung_context+0x19e/0x1d0 [i915] <4> [319.984352] reset_engine+0x99/0xd0 [i915] <4> [319.984399] ? __drm_printfn_seq_file+0x20/0x20 <4> [319.984406] heartbeat+0x4cd/0x4f0 [i915] <4> [319.984454] process_one_work+0x272/0x5b0 <4> [319.984461] worker_thread+0x37/0x370 <4> [319.984465] ? process_one_work+0x5b0/0x5b0 <4> [319.984467] kthread+0xed/0x120 <4> [319.984470] ? kthread_complete_and_exit+0x20/0x20 <4> [319.984474] ret_from_fork+0x1f/0x30 <4> [319.984484] </TASK> <4> [319.984485] irq event stamp: 36107 <4> [319.984487] hardirqs last enabled at (36113): [<ffffffff811391d6>] __up_console_sem+0x66/0x70 <4> [319.984492] hardirqs last disabled at (36118): [<ffffffff811391bb>] __up_console_sem+0x4b/0x70 <4> [319.984494] softirqs last enabled at (34316): [<ffffffff81e00323>] __do_softirq+0x323/0x48e <4> [319.984497] softirqs last disabled at (34309): [<ffffffff810c16b8>] irq_exit_rcu+0xb8/0xe0 <4> [319.984499] ---[ end trace 0000000000000000 ]--- v2: - Instead of trying to fix the suspend/resume sequence, restore simply the state w/o the HW readout/sanitization step.

2022-10-14parisc: Fix userspace graphics card breakage due to pgtable special bitHelge Deller
Commit df24e1783e6e ("parisc: Add vDSO support") introduced the vDSO support, for which a _PAGE_SPECIAL page table flag was needed. Since we wanted to keep every page table entry in 32-bits, this patch re-used the existing - but yet unused - _PAGE_DMB flag (which triggers a hardware break if a page is accessed) to store the special bit. But when graphics card memory is mmapped into userspace, the kernel uses vm_iomap_memory() which sets the the special flag. So, with the DMB bit set, every access to the graphics memory now triggered a hardware exception and segfaulted the userspace program. Fix this breakage by dropping the DMB bit when writing the page protection bits to the CPU TLB. In addition this patch adds a small optimization: if huge pages aren't configured (which is at least the case for 32-bit kernels), then the special bit is stored in the hpage (HUGE PAGE) bit instead. That way we can skip to reset the DMB bit. Fixes: df24e1783e6e ("parisc: Add vDSO support") Cc: <stable@vger.kernel.org> # 5.18+ Signed-off-by: Helge Deller <deller@gmx.de>

Support the CRTC's color-management property and implement each model's palette support. The OF hardware has different methods of setting the palette. The respective code has been taken from fbdev's offb and refactored into per-model device functions. The device functions integrate this functionality into the overall modesetting. As palette handling is a CRTC property that depends on the primary plane's color format, the plane's atomic_check helper now updates the format field in ofdrm's custom CRTC state. The CRTC's atomic_flush helper updates the palette for the format as needed. v4: * use cpu_to_be32() (Geert) v3: * lookup CRTC state with drm_atomic_get_new_crtc_state() * access HW palette with writeb(), writel(), and readl() (Ben) * declare register values as u32 Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221011150712.3928-5-tzimmermann@suse.de

2022-10-14drm/ofdrm: Add ofdrm for Open Firmware framebuffersThomas Zimmermann
Open Firmware provides basic display output via the 'display' node. DT platform code already provides a device that represents the node's framebuffer. Add a DRM driver for the device. The display mode and color format is pre-initialized by the system's firmware. Runtime modesetting via DRM is not possible. The display is useful during early boot stages or as error fallback. Similar functionality is already provided by fbdev's offb driver, which is insufficient for modern userspace. The old driver includes support for BootX device tree, which can be found on old 32-bit PowerPC Macintosh systems. If these are still in use, the functionality can be added to ofdrm or implemented in a new driver. As with simpledrm, the fbdev driver cannot be selected if ofdrm is already enabled. Two notable points about the driver: * Reading the framebuffer aperture from the device tree is not reliable on all systems. Ofdrm takes the heuristics and a comment from offb to pick the correct range. * No resource management may be tied to the underlying PCI device. Otherwise the handover to the native driver will fail with a resource conflict. PCI management is therefore done as part of the platform device's cleanup. The driver has been tested on qemu's ppc64le emulation. The device hand-over has been tested with bochs. v5: * use drm_atomic_helper_check_crtc_primary_plane() v4: * set preferred depth to the correct value * set bpp value for console emulation * output scanout-buffer parameters with drm_dbg() v3: * reintegrate FWFB helpers into ofdrm * use damage iterator * sync GEM BOs with drm_gem_fb_{begin,end}_cpu_access() * fix various atomic_check helpers * remove CRTC atomic_{enable,disable} (Javier) * compute stride with drm_format_info_min_pitch() (Daniel) v2: * removed simple-pipe helpers * built driver on top of FWFB helpers * merged all init code into single function * make PCI support optional (Michal) * support COMPILE_TEST (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> convert Link: https://patchwork.freedesktop.org/patch/msgid/20221011150712.3928-2-tzimmermann@suse.de

Fix this by reallocating ZC with rx_bi_zc struct when BPF program loads. Additionally reallocate back to rx_bi when BPF program unloads. If BPF program is loaded/unloaded and XSK pools are created, reallocate RX queues accordingly in XSP_SETUP_XSK_POOL handler.

The trial period exists until jiffies is after addr_trial_end. But as jiffies will eventually overflow, just using time_after will eventually give incorrect results.
