[PATCH v2] drm/bridge: synopsys/dw-hdmi: set cec clock rate
by Peter Geis 26 Jan '22

26 Jan '22

The hdmi-cec clock must be 32khz in order for cec to work correctly. Ensure before enabling the clock we set it in order for the hardware to work as expected.

[PATCH] [RFC] fbcon: Add option to enable legacy hardware acceleration
by Helge Deller 26 Jan '22

26 Jan '22

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. This patch is the first RFC. Independed of this patch I did some timing experiments with a qemu virtual machine running a PA-RISC Debian Linux installation with a screen resolution of 2048x1024 with 8bpp. In that case qemu emulated the graphics hardware bitblt and fillrect acceleration by using the native (x86) CPU. It was a simple testcase which was to run "time dmesg", where the syslog had 284 lines. The results showed a huge speedup: a) time dmesg (without acceleration): -> 19.0 seconds b) time dmesg (with acceleration): -> 2.6 seconds Signed-off-by: Helge Deller <deller(a)gmx.de> diff --git a/drivers/video/console/Kconfig b/drivers/video/console/Kconfig index 840d9813b0bc..da84d1c21c21 100644 --- a/drivers/video/console/Kconfig +++ b/drivers/video/console/Kconfig @@ -78,6 +78,17 @@ config FRAMEBUFFER_CONSOLE help Low-level framebuffer-based console driver. +config FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION + bool "Framebuffer Console hardware acceleration support" + depends on FRAMEBUFFER_CONSOLE + default y if !DRM + default y if !(X86 || ARM) + help + If you use a system on which DRM is fully supported you usually want to say N, + otherwise you probably want to enable this option. + If enabled the framebuffer console will utilize the hardware acceleration + of your graphics card by using hardware bitblt and fillrect features. + config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY bool "Map the console to the primary display device" depends on FRAMEBUFFER_CONSOLE diff --git a/drivers/video/fbdev/core/fbcon.c b/drivers/video/fbdev/core/fbcon.c index b813985f1403..f7b7d35953e8 100644 --- a/drivers/video/fbdev/core/fbcon.c +++ b/drivers/video/fbdev/core/fbcon.c @@ -1136,11 +1136,13 @@ static void fbcon_init(struct vc_data *vc, int init) ops->graphics = 0; +#ifdef CONFIG_FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION if ((cap & FBINFO_HWACCEL_COPYAREA) && !(cap & FBINFO_HWACCEL_DISABLED)) p->scrollmode = SCROLL_MOVE; else /* default to something safe */ p->scrollmode = SCROLL_REDRAW; +#endif /* * ++guenther: console.c:vc_allocate() relies on initializing @@ -1705,7 +1707,7 @@ static bool fbcon_scroll(struct vc_data *vc, unsigned int t, unsigned int b, count = vc->vc_rows; if (logo_shown >= 0) goto redraw_up; - switch (p->scrollmode) { + switch (fb_scrollmode(p)) { case SCROLL_MOVE: fbcon_redraw_blit(vc, info, p, t, b - t - count, count); @@ -1795,7 +1797,7 @@ static bool fbcon_scroll(struct vc_data *vc, unsigned int t, unsigned int b, count = vc->vc_rows; if (logo_shown >= 0) goto redraw_down; - switch (p->scrollmode) { + switch (fb_scrollmode(p)) { case SCROLL_MOVE: fbcon_redraw_blit(vc, info, p, b - 1, b - t - count, -count); @@ -1946,12 +1948,12 @@ static void fbcon_bmove_rec(struct vc_data *vc, struct fbcon_display *p, int sy, height, width); } -static void updatescrollmode(struct fbcon_display *p, +static void updatescrollmode_accel(struct fbcon_display *p, struct fb_info *info, struct vc_data *vc) { +#ifdef CONFIG_FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION struct fbcon_ops *ops = info->fbcon_par; - int fh = vc->vc_font.height; int cap = info->flags; u16 t = 0; int ypan = FBCON_SWAP(ops->rotate, info->fix.ypanstep, @@ -1972,12 +1974,6 @@ static void updatescrollmode(struct fbcon_display *p, int fast_imageblit = (cap & FBINFO_HWACCEL_IMAGEBLIT) && !(cap & FBINFO_HWACCEL_DISABLED); - p->vrows = vyres/fh; - if (yres > (fh * (vc->vc_rows + 1))) - p->vrows -= (yres - (fh * vc->vc_rows)) / fh; - if ((yres % fh) && (vyres % fh < yres % fh)) - p->vrows--; - if (good_wrap || good_pan) { if (reading_fast || fast_copyarea) p->scrollmode = good_wrap ?

[PATCH v5 00/10] Add GuC Error Capture Support
by Alan Previn 26 Jan '22

26 Jan '22

This series: 1. Enables support of GuC to execute error- state-capture based on a list of MMIO registers the driver registers and GuC will dump and report back right before a GuC triggered engine-reset event. 2. Updates the ADS blob creation to register lists of global and engine registers with GuC. 3. Defines tables of register lists that are global or engine class or engine instance in scope. 4. Separates GuC log-buffer access locks for relay logging vs the new region for the error state capture data. 5. Allocates an additional interim circular buffer store to copy snapshots of new GuC reported error-state-capture dumps in response to the G2H notification. 6. Connects the i915_gpu_coredump reporting function to the GuC error capture module to print all GuC error state capture dumps that is reported. This is the 5th rev of this series with the first 3 revs labelled as RFC. Prior receipts of rvb's: - Patch #5 has received R-v-b from Matthew Brost <matthew.brost(a)intel.com> Changes from prior revs: v5: - Added Gen9->Gen11 register list for CI coverage that included Gen9 with GuC submission. - Redesigned the extraction of the GuC error-capture dumps by grouping them into complete per-engine-reset nodes. Complete here means each node includes the global, engine-class and engine-instance register lists in a single structure. - Extraction is decoupled from the print-out. We now do the extraction immediately when receiving the G2H for error-capture notification. A link list of nodes is maintained with a FIFO based threshold while awaiting retrieval from i915_gpu_coredump's capture_engine function. - Added new plumbing through the i915_gpu_coredump allocation and capture functions to include a flag that is used indicate that GuC had triggered the reset. This new plumbing guarantees an exact match from i915_gpu_coredump's per-engine vma recording and node-retrieval from the guc-error-capture. - Broke the coredump gt_global capture and recording functions into smaller subsets so we can reuse as much of the existing legacy register reading + printing functions and only rely on GuC error-capture for the smaller subset of registers that are tied to engine workload execution. - Updated the register list to follow the legacy execlist format of printout. v4: - Rebased on latest drm-tip that has been merged with the support of GuC firmware version 69.0.3 that is required for GuC error-state-catpure to work. - Added register list for DG2 which is the same as XE_LP except an additional steering register set. - Fixed a bug in the end of capture parsing loop in intel_guc_capture_out_print_next_group that was not properly comparing the engine-instance and engine- class being parsed against the one that triggered the i915_gpu_coredump. v3: - Fixed all review comments from rev2 except the following: - Michal Wajdeczko proposed adding a seperate function to lookup register string nameslookup (based on offset) but decided against it because of offset conflicts and the current table layout is easier to maintain. - Last set of checkpatch errors pertaining to "COMPLEX MACROS" should be fixed on next rev. - Abstracted internal-to-guc-capture information into a new __guc_state_capture_priv structure that allows the exclusion of intel_guc.h and intel_guc_fwif.h from intel_guc_capture.h. Now, only the first 2 patches have a wider build time impact because of the changes to intel_guc_fwif.h but subsequent changes to guc-capture internal structures or firmware interfaces used solely by guc-capture module shoudn't impact the rest of the driver build. - Added missing Gen12LP registers and added slice+subslice indices when reporting extended steered registers. - Add additional checks to ensure that the GuC reported error capture information matches the i915_gpu_coredump that is being printed before we print out the corresponding VMA dumps such as the batch buffer. v2: - Ignore - failed CI retest.

[PATCH][next] drm/i915/guc: Use struct_size() helper in kmalloc()
by Gustavo A. R. Silva 26 Jan '22

Make use of the struct_size() helper instead of an open-coded version, in order to avoid any potential type mistakes or integer overflows that, in the worst scenario, could lead to heap overflows. Also, address the following sparse warnings: drivers/gpu/drm/i915/gt/uc/intel_guc_ct.c:792:23: warning: using sizeof on a flexible structure Link: https://github.com/KSPP/linux/issues/174 Signed-off-by: Gustavo A.

[PATCH 17/54] gpu: drm: replace cpumask_weight with cpumask_empty where appropriate
by Yury Norov 26 Jan '22

26 Jan '22

i915_pmu_cpu_online() calls cpumask_weight() to check if any bit of a given cpumask is set. We can do it more efficiently with cpumask_empty() because cpumask_empty() stops traversing the cpumask as soon as it finds first set bit, while cpumask_weight() counts all bits unconditionally.
