Andrew Morton pointed this out a month ago, and then I completely forgot about it. If we read a partial last page of a block device, we will zero out the end of the page, but since that page can then be mapped into user space, we should also make sure to flush the cache on architectures that have virtual caches. We have the flush_dcache_page() function for this, so use it. Now, in practice this really never matters, because nobody sane uses virtual caches to begin with, and they largely exist on old broken RISC arhitectures. And even if you did run on one of those obsolete CPU's, the whole "mmap and access the last partial page of a block device" behavior probably doesn't actually exist. The normal IO functions (read/write) will never see the zeroed-out part of the page that migth not be coherent in the cache, because they honor the size of the device. So I'm marking this for stable (3.7 only), but I'm not sure anybody will ever care.

udldrmfb only reads the main EDID block, and if that advertises extensions the drm_edid code expects them to be present, and starts reading beyond the buffer udldrmfb passes it. Although it may be possible to read more EDID info with the udl we simpy don't know how, and even if trial and error gets it working on one device, that is no guarantee it will work on other revisions. So this patch does a simple fix in the form of patching the EDID info to report 0 extension blocks, this fixes udldrmfb only doing 1024x768 on monitors with EDID extension blocks.

Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate from create/destroy") started to call display init routines on pre-nv50 hardware on module load. But LVDS init code sets driver state in a way which prevents modesetting code from operating properly. nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to NV_DPMS_CLEARED. drm_crtc_helper_set_mode nv04_dfp_prepare nv04_lvds_dpms(DRM_MODE_DPMS_OFF) nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too, so it skips calling some crucial lvds scripts.

This fix was put in place to fix a bug where the eDP panel on certain laptops fails to respond over the aux channel after suspend. It appears that on some systems (Dell M6600, with LVDS panel) there's a very bad interaction with the eDP init table that causes the SOR to get very confused and not drive the panel correctly, leading to bleed. A DPMS off/on cycle is enough to bring it back, but, this will avoid the problem by not touching the panel GPIOs at times we're not meant to. Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

由 Sathya Perla 提交于
commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx() to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel from detecting interrupt storms due to broken HW. The BE2/Lancer HW issues are: 1) In Lancer, there is no means for the driver to detect if the interrupt belonged to device, other than counting and notifying events. 2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler to be called multiple times till the de-assert happens. 3) In BE2, we see an occasional interrupt even when EQs are unarmed. Issue (1) can cause the notified events to be orphaned, if NAPI was already running. This patch fixes this issue by scheduling NAPI only if it is not scheduled already. Doing this also takes care of possible events_get() race that may be caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first time zero events are detected.

Michael points out that even after Stefan's fix the TUNSETIFF is still allowed to create a new tap device. This because we only check tfile->tun but the tfile->detached were introduced. Fix this by failing early in tun_set_iff() if the file is detached. After this fix, there's no need to do the check again in tun_set_iff(), so this patch removes it. Cc: Michael S.
