During pipe DPMS off, instead of busy waiting pipe off, insert delays during wait and don't loop after enough tries which matches spec requirement. Also try to match DPMS on path by disable FDI TX PLL in DPMS off. Disable PF by writing PF_WIN_SZ which really trigger the update.

Now the DVO timing in LVDS data entry is obtained by using the following step: a. get the entry size for every LVDS panel data b. Get the LVDS fp entry for the preferred panel type c. get the DVO timing by using entry->dvo_timing In our driver the entry->dvo_timing is related with the size of lvds_fp_timing. For example: the size is 46. But it seems that the size of lvds_fp_timing varies on the differnt platform. In such case we will get the incorrect DVO timing entry because of the incorrect DVO offset in LVDS panel data entry. This also removes a hack on new IGDNG to get proper DVO timing. Calculate the DVO timing offset in LVDS data entry to get the DVO timing a. get the DVO timing offset in the LVDS fp data entry by using the pointer definition in LVDS data ptr b. get the LVDS data entry c. get the DVO timing by adding the DVO timing offset to data entry https://bugs.freedesktop.org/show_bug.cgi?id=22787Signed-off-by: NZhao Yakui <yakui.zhao@intel.com> Tested-by: NZhenyu Wang <zhenyuw@linux.intel.com> Acked-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NEric Anholt <eric@anholt.net>

According to investigations from windows team ,hw team, and our test results on all 4x platofrms available (gm45, g45b, q45, g45a, g45c, g41a, and g41), we find currently Hot plug live status and Hot plug interrupt detection are not reliable, sometime the results from the two approaches are contradicts. So we chose edid detection for hdmi output. Signed-off-by: NMa Ling <ling.ma@intel.com> Reviewed-by: NIan Romanick <ian.d.romanick@intel.com> Signed-off-by: NEric Anholt <eric@anholt.net>

If you're pushing a plane hard (i.e. you need most or all of the FIFO entries just to cover your frame refresh latency), the watermark level may end up being negative. So fix up the signed vs. unsigned math in the calculation function to handle this correctly, giving all available FIFO entries to such a configuration.

I discovered several bugs in the FIFO code that was recently applied. Some of them fell into the "how did this ever work" category, since in some cases we were using the wrong FIFO size values, and the calculations ended up being way off. This patch fixes all the bugs I found, and works well on my GM45, 915GM and 855GM test machines; but as usual with these sorts of patches broader testing is definitely requested (in particular this patch affects 830, 845 and 865 for which I don't have test hardware). Overall, the patch clarifies the watermark calculation function by adding some comments and debug info, and making the variable names a bit clearer. The "get FIFO size" portion of the code has also been corrected, so we should be able to properly detect the FIFO allocations for each pipe, for use in the watermark calculation.

The 915 and 945 scanout engines can handle frame buffers up to 4096 pixels wide. Pre-9xx hardware has an 8192 byte stride limit, and so we leave the existing 2048 max in place.

We have found that the current PER_CLEAR_ON_SETID mask on Linux doesn't include neither ADDR_COMPAT_LAYOUT, nor MMAP_PAGE_ZERO. The current mask is READ_IMPLIES_EXEC|ADDR_NO_RANDOMIZE. We believe it is important to add MMAP_PAGE_ZERO, because by using this personality it is possible to have the first page mapped inside a process running as setuid root. This could be used in those scenarios: - Exploiting a NULL pointer dereference issue in a setuid root binary - Bypassing the mmap_min_addr restrictions of the Linux kernel: by running a setuid binary that would drop privileges before giving us control back (for instance by loading a user-supplied library), we could get the first page mapped in a process we control. By further using mremap and mprotect on this mapping, we can then completely bypass the mmap_min_addr restrictions. Less importantly, we believe ADDR_COMPAT_LAYOUT should also be added since on x86 32bits it will in practice disable most of the address space layout randomization (only the stack will remain randomized).

This causes kernel images that don't run init to completion with certain broken gcc versions.
