I've tested this and experimented around a bit and came up with code like this:
bool check_sync;
struct ast_vbios_enhtable *best = NULL;
[..]
refresh_rate = drm_mode_vrefresh(mode);
check_sync = vbios_mode->enh_table->flags & WideScreenMode;
do {
struct ast_vbios_enhtable *loop = best = vbios_mode->enh_table;
while (loop->refresh_rate != 0xff) {
if ((check_sync) &&
(((mode->flags & DRM_MODE_FLAG_NVSYNC) &&
(loop->flags & PVSync)) ||
((mode->flags & DRM_MODE_FLAG_PVSYNC) &&
(loop->flags & NVSync)) ||
((mode->flags & DRM_MODE_FLAG_NHSYNC) &&
(loop->flags & PHSync)) ||
((mode->flags & DRM_MODE_FLAG_PHSYNC) &&
(loop->flags & NHSync)))) {
loop++;
continue;
}
if (loop->refresh_rate <= refresh_rate
&& loop->refresh_rate > best->refresh_rate)
best = loop;
loop++;
}
if (!check_sync)
break;
check_sync = 0;
} while (1);
if (!best)
return false;
vbios_mode->enh_table = best;
This way the code doesn't make the assumption that the refresh rates
are in ascending order and we can map the sync polarities for all modes,
not just the wide screen ones.

This should be:

I've tested this and experimented around a bit and came up with code like this:
bool check_sync;
struct ast_vbios_enhtable *best = NULL;
[..]
refresh_rate = drm_mode_vrefresh(mode);
check_sync = vbios_mode->enh_table->flags & WideScreenMode;
do {
struct ast_vbios_enhtable *loop = best = vbios_mode->enh_table;
while (loop->refresh_rate != 0xff) {
if ((check_sync) &&
(((mode->flags & DRM_MODE_FLAG_NVSYNC) &&
(loop->flags & PVSync)) ||
((mode->flags & DRM_MODE_FLAG_PVSYNC) &&
(loop->flags & NVSync)) ||
((mode->flags & DRM_MODE_FLAG_NHSYNC) &&
(loop->flags & PHSync)) ||
((mode->flags & DRM_MODE_FLAG_PHSYNC) &&
(loop->flags & NHSync)))) {
loop++;
continue;
}
if (loop->refresh_rate <= refresh_rate
&& loop->refresh_rate > best->refresh_rate)
best = loop;
loop++;
}
if (!check_sync)
break;
check_sync = 0;
} while (1);
if (!best)
return false;
vbios_mode->enh_table = best;
This way the code doesn't make the assumption that the refresh rates
are in ascending order and we can map the sync polarities for all modes,
not just the wide screen ones.

Hi Egbert,
Thanks for your comment. The modification is great. If possible, could you create a new patch to patch my original patch?

Hi YC,
you should probably be a bit more verbose in your changelog entry.
As subject something like:
Add reduced blanking modes for wide screen mode
As text:
Add reduced blanking modes, improve mode matching to
identify these modes by their sync polarities.

Weren't you going to put this line into a separate patch
- as it fixes a 'run off the end of the list' bug?
